hg

Mercurial source code management system

- Execute Mercurial command:
hg [command]

- Call general help:
hg help

- Call help on a command:
hg help [command]

- Check the Mercurial version:
hg --version

hg command [option]... [argument]...

The hg command provides a command line interface to the Mercurial system.

files...

indicates one or more filename or relative path filenames; see File Name Patterns for information on pattern matching
path

indicates a path on the local machine

revision
indicates a changeset which can be specified as a changeset revision number, a tag, or a unique substring of the changeset hash value
repository path
either the pathname of a local repository or the URI of a remote repository.

-R, --repository

repository root directory or name of overlay bundle file
--cwd

change working directory

-y, --noninteractive
do not prompt, assume 'yes' for any required answers
-q, --quiet
suppress output
-v, --verbose
enable additional output
--config
set/override config option
--debug
enable debugging output
--debugger
start debugger
--encoding
set the charset encoding (default: UTF-8)
--encodingmode
set the charset encoding mode (default: strict)
--traceback
always print a traceback on exception
--time

time how long the command takes

--profile
print command execution profile
--version
output version information and exit
-h, --help
display help and exit

add [OPTION]... [FILE]...

Schedule files to be version controlled and added to the repository.

The files will be added to the repository at the next commit. To undo an add before that, see hg forget.

If no names are given, add all files to the repository.

options:

-I, --include

include names matching the given patterns

-X, --exclude

exclude names matching the given patterns

-n, --dry-run

do not perform actions, just print output

addremove [OPTION]... [FILE]...
Add all new files and remove all missing files from the repository.

New files are ignored if they match any of the patterns in commit.

Use the -s/--similarity option to detect renamed files. With a parameter greater than 0, this compares every removed file with every added file and records those similar enough as renames. This option takes a percentage between 0 (disabled) and 100 (files must be identical) as its parameter. Detecting renamed files this way can be expensive.

options:

-s, --similarity

guess renamed files by similarity (0<=s<=100)

-I, --include

include names matching the given patterns

-X, --exclude

exclude names matching the given patterns

-n, --dry-run

do not perform actions, just print output

annotate [-r REV] [-f] [-a] [-u] [-d] [-n] [-c] [-l] FILE...
List changes in files, showing the revision id responsible for each line

This command is useful for discovering when a change was made and by whom.

Without the -a/--text option, annotate will avoid processing files it detects as binary. With -a, annotate will annotate the file anyway, although the results will probably be neither useful nor desirable.

options:

-r, --rev

annotate the specified revision

-f, --follow

follow file copies and renames

-a, --text

treat all files as text

-u, --user

list the author (long with -v)

-d, --date

list the date (short with -q)

-n, --number

list the revision number (default)

-c, --changeset

list the changeset

-l, --line-number

show line number at the first appearance

-I, --include

include names matching the given patterns

-X, --exclude

exclude names matching the given patterns

aliases: blame
archive [OPTION]... DEST
By default, the revision used is the parent of the working directory; use -r/--rev to specify a different revision.

To specify the type of archive to create, use -t/--type. Valid types are:

"files" (default): a directory full of files "tar": tar archive, uncompressed "tbz2": tar archive, compressed using bzip2 "tgz": tar archive, compressed using gzip "uzip": zip archive, uncompressed "zip": zip archive, compressed using deflate
The exact name of the destination archive or directory is given using a format string; see 'hg help export' for details.

Each member added to an archive file has a directory prefix prepended. Use -p/--prefix to specify a format string for the prefix. The default is the basename of the archive, with suffixes removed.

options:

--no-decode

do not pass files through decoders

-p, --prefix

directory prefix for files in archive

-r, --rev

revision to distribute

-t, --type

type of distribution to create

-I, --include

include names matching the given patterns

-X, --exclude

exclude names matching the given patterns

backout [OPTION]... [-r] REV
Commit the backed out changes as a new changeset. The new changeset is a child of the backed out changeset.

If you backout a changeset other than the tip, a new head is created. This head will be the new tip and you should merge this backout changeset with another head.

The --merge option remembers the parent of the working directory before starting the backout, then merges the new head with that changeset afterwards. This saves you from doing the merge by hand. The result of this merge is not committed, as with a normal merge.

See 'hg help dates' for a list of formats valid for -d/--date.

options:

--merge

merge with old dirstate parent after backout

--parent

parent to choose when backing out merge

-r, --rev

revision to backout

-I, --include

include names matching the given patterns

-X, --exclude

exclude names matching the given patterns

-m, --message

use <text> as commit message

-l, --logfile

read commit message from <file>

-d, --date

record datecode as commit date

-u, --user

record the specified user as committer

bisect [-gbsr] [-c CMD] [REV]
This command helps to find changesets which introduce problems. To use, mark the earliest changeset you know exhibits the problem as bad, then mark the latest changeset which is free from the problem as good. Bisect will update your working directory to a revision for testing (unless the -U/--noupdate option is specified). Once you have performed tests, mark the working directory as good or bad, and bisect will either update to another candidate changeset or announce that it has found the bad revision.

As a shortcut, you can also use the revision argument to mark a revision as good or bad without checking it out first.

If you supply a command, it will be used for automatic bisection. Its exit status will be used to mark revisions as good or bad: status 0 means good, 125 means to skip the revision, 127 (command not found) will abort the bisection, and any other non-zero exit status means the revision is bad.

options:

-r, --reset

reset bisect state

-g, --good

mark changeset good

-b, --bad

mark changeset bad

-s, --skip

skip testing changeset

-c, --command

use command to check changeset state

-U, --noupdate

do not update to target

branch [-fC] [NAME]
With no argument, show the current branch name. With one argument, set the working directory branch name (the branch will not exist in the repository until the next commit). Standard practice recommends that primary development take place on the 'default' branch.

Unless -f/--force is specified, branch will not let you set a branch name that already exists, even if it's inactive.

Use -C/--clean to reset the working directory branch to that of the parent of the working directory, negating a previous branch change.

Use the command 'hg update' to switch to an existing branch. Use 'hg commit --close-branch' to mark this branch as closed.

options:

-f, --force

set branch name even if it shadows an existing branch

-C, --clean

reset branch name to parent branch name

branches [-a]
List the repository's named branches, indicating which ones are inactive. If -c/--closed is specified, also list branches which have been marked closed (see hg commit --close-branch).

If -a/--active is specified, only show active branches. A branch is considered active if it contains repository heads.

Use the command 'hg update' to switch to an existing branch.

options:

-a, --active

show only branches that have unmerged heads

-c, --closed

show normal and closed branches

bundle [-f] [-a] [-r REV]... [--base REV]... FILE [DEST]
Generate a compressed changegroup file collecting changesets not known to be in another repository.

If no destination repository is specified the destination is assumed to have all the nodes specified by one or more --base parameters. To create a bundle containing all changesets, use -a/--all (or --base null).

You can change compression method with the -t/--type option. The available compression methods are: none, bzip2, and gzip (by default, bundles are compressed using bzip2).

The bundle file can then be transferred using conventional means and applied to another repository with the unbundle or pull command. This is useful when direct push and pull are not available or when exporting an entire repository is undesirable.

Applying bundles preserves all changeset contents including permissions, copy/rename information, and revision history.

options:

-f, --force

run even when remote repository is unrelated

-r, --rev

a changeset up to which you would like to bundle

--base

a base changeset to specify instead of a destination

-a, --all

bundle all changesets in the repository

-t, --type

bundle compression type to use (default: bzip2)

-e, --ssh

specify ssh command to use

--remotecmd

specify hg command to run on the remote side

cat [OPTION]... FILE...
Print the specified files as they were at the given revision. If no revision is given, the parent of the working directory is used, or tip if no revision is checked out.

Output may be to a file, in which case the name of the file is given using a format string. The formatting rules are the same as for the export command, with the following additions:

%s basename of file being printed %d dirname of file being printed, or '.' if in repository root %p root-relative path name of file being printed
options:
-o, --output

print output to file with formatted name

-r, --rev

print the given revision

--decode

apply any matching decode filter

-I, --include

include names matching the given patterns

-X, --exclude

exclude names matching the given patterns

clone [OPTION]... SOURCE [DEST]
Create a copy of an existing repository in a new directory.

If no destination directory name is specified, it defaults to the basename of the source.

The location of the source is added to the new repository's

See 'hg help urls' for valid source format details.

It is possible to specify an ssh:// URL as the destination, but no Please see 'hg help urls' for important details about ssh:// URLs.

If the -U/--noupdate option is specified, the new clone will contain only a repository (.hg) and no working copy (the working copy parent will be the null changeset). Otherwise, clone will initially check out (in order of precedence):

a.

the changeset, tag or branch specified with -u/--updaterev

b.

the changeset, tag or branch given with the first -r/--rev

c.

the head of the default branch

Use 'hg clone -u . src dst' to checkout the source repository's parent changeset (applicable for local source repositories only).

A set of changesets (tags, or branch names) to pull may be specified by listing each changeset (tag, or branch name) with -r/--rev. If -r/--rev is used, the cloned repository will contain only a subset of the changesets of the source repository. Only the set of changesets defined by all -r/--rev options (including all their ancestors) will be pulled into the destination repository. No subsequent changesets (including subsequent tags) will be present in the destination.

Using -r/--rev (or 'clone src#rev dest') implies --pull, even for local source repositories.

For efficiency, hardlinks are used for cloning whenever the source and destination are on the same filesystem (note this applies only to the repository data, not to the checked out files). Some filesystems, such as AFS, implement hardlinking incorrectly, but do not report errors. In these cases, use the --pull option to avoid hardlinking.

In some cases, you can clone repositories and checked out files using full hardlinks with

$ cp -al REPO REPOCLONE
This is the fastest way to clone, but it is not always safe. The operation is not atomic (making sure REPO is not modified during the operation is up to you) and you have to make sure your editor breaks hardlinks (Emacs and most Linux Kernel tools do so). Also, this is not compatible with certain extensions that place their metadata under the .hg directory, such as mq.

options:

-U, --noupdate

the clone will only contain a repository (no working copy)

-u, --updaterev

revision, tag or branch to check out

-r, --rev

a changeset you would like to have after cloning

--pull

use pull protocol to copy metadata

--uncompressed

use uncompressed transfer (fast over LAN)

-e, --ssh

specify ssh command to use

--remotecmd

specify hg command to run on the remote side

commit [OPTION]... [FILE]...
Commit changes to the given files into the repository. Unlike a centralized RCS, this operation is a local operation. See hg push for a way to actively distribute your changes.

If a list of files is omitted, all changes reported by "hg status" will be committed.

If you are committing the result of a merge, do not provide any filenames or -I/-X filters.

If no commit message is specified, the configured editor is started to prompt you for a message.

See 'hg help dates' for a list of formats valid for -d/--date.

options:

-A, --addremove

mark new/missing files as added/removed before committing

--close-branch

mark a branch as closed, hiding it from the branch list

-I, --include

include names matching the given patterns

-X, --exclude

exclude names matching the given patterns

-m, --message

use <text> as commit message

-l, --logfile

read commit message from <file>

-d, --date

record datecode as commit date

-u, --user

record the specified user as committer

aliases: ci
copy [OPTION]... [SOURCE]... DEST
Mark dest as having copies of source files. If dest is a directory, copies are put in that directory. If dest is a file, the source must be a single file.

By default, this command copies the contents of files as they exist in the working directory. If invoked with -A/--after, the operation is recorded, but no copying is performed.

This command takes effect with the next commit. To undo a copy before that, see hg revert.

options:

-A, --after

record a copy that has already occurred

-f, --force

forcibly copy over an existing managed file

-I, --include

include names matching the given patterns

-X, --exclude

exclude names matching the given patterns

-n, --dry-run

do not perform actions, just print output

aliases: cp
diff [OPTION]... [-r REV1 [-r REV2]] [FILE]...
Show differences between revisions for the specified files.

Differences between files are shown using the unified diff format.

NOTE: diff may generate unexpected results for merges, as it will default to comparing against the working directory's first parent changeset if no revisions are specified.

When two revision arguments are given, then changes are shown between those revisions. If only one revision is specified then that revision is compared to the working directory, and, when no revisions are specified, the working directory files are compared to its parent.

Without the -a/--text option, diff will avoid generating diffs of files it detects as binary. With -a, diff will generate a diff anyway, probably with undesirable results.

Use the -g/--git option to generate diffs in the git extended diff format. For more information, read 'hg help diffs'.

options:

-r, --rev

revision

-c, --change

change made by revision

-a, --text

treat all files as text

-g, --git

use git extended diff format

--nodates

don't include dates in diff headers

-p, --show-function

show which function each change is in

--reverse

produce a diff that undoes the changes

-w, --ignore-all-space

ignore white space when comparing lines

-b, --ignore-space-change

ignore changes in the amount of white space

-B, --ignore-blank-lines

ignore changes whose lines are all blank

-U, --unified

number of lines of context to show

--stat

output diffstat-style summary of changes

-I, --include

include names matching the given patterns

-X, --exclude

exclude names matching the given patterns

export [OPTION]... [-o OUTFILESPEC] REV...
Print the changeset header and diffs for one or more revisions.

The information shown in the changeset header is: author, changeset hash, parent(s) and commit comment.

NOTE: export may generate unexpected diff output for merge changesets, as it will compare the merge changeset against its first parent only.

Output may be to a file, in which case the name of the file is given using a format string. The formatting rules are as follows:

%% literal "%" character %H changeset hash (40 bytes of hexadecimal) %N number of patches being generated %R changeset revision number %b basename of the exporting repository %h short-form changeset hash (12 bytes of hexadecimal) %n zero-padded sequence number, starting at 1 %r zero-padded changeset revision number
Without the -a/--text option, export will avoid generating diffs of files it detects as binary. With -a, export will generate a diff anyway, probably with undesirable results.

Use the -g/--git option to generate diffs in the git extended diff format. See 'hg help diffs' for more information.

With the --switch-parent option, the diff will be against the second parent. It can be useful to review a merge.

options:

-o, --output

print output to file with formatted name

--switch-parent

diff against the second parent

-a, --text

treat all files as text

-g, --git

use git extended diff format

--nodates

don't include dates in diff headers

forget [OPTION]... FILE...
Mark the specified files so they will no longer be tracked after the next commit.

This only removes files from the current branch, not from the entire project history, and it does not delete them from the working directory.

To undo a forget before the next commit, see hg add.

options:

-I, --include

include names matching the given patterns

-X, --exclude

exclude names matching the given patterns

grep [OPTION]... PATTERN [FILE]...
Search revisions of files for a regular expression.

This command behaves differently than Unix grep. It only accepts Python/Perl regexps. It searches repository history, not the working directory. It always prints the revision number in which a match appears.

By default, grep only prints output for the first revision of a file in which it finds a match. To get it to print every revision that contains a change in match status ("-" for a match that becomes a non-match, or "+" for a non-match that becomes a match), use the --all flag.

options:

-0, --print0

end fields with NUL

--all

print all revisions that match

-f, --follow

follow changeset history, or file history across copies and renames

-i, --ignore-case

ignore case when matching

-l, --files-with-matches

print only filenames and revisions that match

-n, --line-number

print matching line numbers

-r, --rev

search in given revision range

-u, --user

list the author (long with -v)

-d, --date

list the date (short with -q)

-I, --include

include names matching the given patterns

-X, --exclude

exclude names matching the given patterns

heads [-r STARTREV] [REV]...
With no arguments, show all repository head changesets.

Repository "heads" are changesets with no child changesets. They are where development generally takes place and are the usual targets for update and merge operations.

If one or more REV is given, the "branch heads" will be shown for the named branch associated with the specified changeset(s).

Branch heads are changesets on a named branch with no descendants on the same branch. A branch head could be a "true" (repository) head, or it could be the last changeset on that branch before it was merged into another branch, or it could be the last changeset on the branch before a new branch was created. If none of the branch heads are true heads, the branch is considered inactive.

If -c/--closed is specified, also show branch heads marked closed (see hg commit --close-branch).

If STARTREV is specified, only those heads that are descendants of STARTREV will be displayed.

options:

-r, --rev

show only heads which are descendants of REV

-a, --active

show only the active branch heads from open branches

-c, --closed

show normal and closed branch heads

--style

display using template map file

--template

display with template

help [TOPIC]
With no arguments, print a list of commands with short help messages.

Given a topic, extension, or command name, print help for that topic.

identify [-nibt] [-r REV] [SOURCE]
With no revision, print a summary of the current state of the repository.

Specifying a path to a repository root or Mercurial bundle will cause lookup to operate on that repository/bundle.

This summary identifies the repository state using one or two parent hash identifiers, followed by a "+" if there are uncommitted changes in the working directory, a list of tags for this revision and a branch name for non-default branches.

options:

-r, --rev

identify the specified revision

-n, --num

show local revision number

-i, --id

show global revision id

-b, --branch

show branch

-t, --tags

show tags

aliases: id
import [OPTION]... PATCH...
Import a list of patches and commit them individually (unless --no-commit is specified).

If there are outstanding changes in the working directory, import will abort unless given the -f/--force flag.

You can import a patch straight from a mail message. Even patches as attachments work (to use the body part, it must have type text/plain or text/x-patch). From and Subject headers of email message are used as default committer and commit message. All text/plain body parts before first diff are added to commit message.

If the imported patch was generated by hg export, user and description from patch override values from message headers and body. Values given on command line with -m/--message and -u/--user override these.

If --exact is specified, import will set the working directory to the parent of each patch before applying it, and will abort if the resulting changeset has a different ID than the one recorded in the patch. This may happen due to character set problems or other deficiencies in the text patch format.

With -s/--similarity, hg will attempt to discover renames and copies in the patch in the same way as 'addremove'.

To read a patch from standard input, use "-" as the patch name. If a URL is specified, the patch will be downloaded from it. See 'hg help dates' for a list of formats valid for -d/--date.

options:

-p, --strip

directory strip option for patch. This has the same meaning as the corresponding patch option (default: 1)

-b, --base

base path

-f, --force

skip check for outstanding uncommitted changes

--no-commit

don't commit, just update the working directory

--exact

apply patch to the nodes from which it was generated

--import-branch

use any branch information in patch (implied by --exact)

-m, --message

use <text> as commit message

-l, --logfile

read commit message from <file>

-d, --date

record datecode as commit date

-u, --user

record the specified user as committer

-s, --similarity

guess renamed files by similarity (0<=s<=100)

aliases: patch
incoming [-p] [-n] [-M] [-f] [-r REV]... [--bundle FILENAME] [SOURCE]
Show new changesets found in the specified path/URL or the default pull location. These are the changesets that would have been pulled if a pull at the time you issued this command.

For remote repository, using --bundle avoids downloading the changesets twice if the incoming is followed by a pull.

See pull for valid source format details.

options:

-f, --force

run even when remote repository is unrelated

-n, --newest-first

show newest record first

--bundle

file to store the bundles into

-r, --rev

a specific remote revision up to which you would like to pull

-p, --patch

show patch

-g, --git

use git extended diff format

-l, --limit

limit number of changes displayed

-M, --no-merges

do not show merges

--style

display using template map file

--template

display with template

-e, --ssh

specify ssh command to use

--remotecmd

specify hg command to run on the remote side

aliases: in
init [-e CMD] [--remotecmd CMD] [DEST]
Initialize a new repository in the given directory. If the given directory does not exist, it will be created.

If no directory is given, the current directory is used.

It is possible to specify an ssh:// URL as the destination. See 'hg help urls' for more information.

options:

-e, --ssh

specify ssh command to use

--remotecmd

specify hg command to run on the remote side

locate [OPTION]... [PATTERN]...
Print files under Mercurial control in the working directory whose names match the given patterns.

By default, this command searches all directories in the working directory. To search just the current directory and its subdirectories, use "--include .".

If no patterns are given to match, this command prints the names of all files under Mercurial control in the working directory.

If you want to feed the output of this command into the "xargs" command, use the -0 option to both this command and "xargs". This will avoid the problem of "xargs" treating single filenames that contain whitespace as multiple filenames.

options:

-r, --rev

search the repository as it stood at REV

-0, --print0

end filenames with NUL, for use with xargs

-f, --fullpath

print complete paths from the filesystem root

-I, --include

include names matching the given patterns

-X, --exclude

exclude names matching the given patterns

log [OPTION]... [FILE]
Print the revision history of the specified files or the entire project.

File history is shown without following rename or copy history of files. Use -f/--follow with a filename to follow history across renames and copies. --follow without a filename will only show ancestors or descendants of the starting revision. --follow-first only follows the first parent of merge revisions.

If no revision range is specified, the default is tip:0 unless --follow is set, in which case the working directory parent is used as the starting revision.

See 'hg help dates' for a list of formats valid for -d/--date.

By default this command prints revision number and changeset id, tags, non-trivial parents, user, date and time, and a summary for each commit. When the -v/--verbose switch is used, the list of changed files and full commit message are shown.

NOTE: log -p/--patch may generate unexpected diff output for merge changesets, as it will only compare the merge changeset against its first parent. Also, only files different from BOTH parents will appear in files:.

options:

-f, --follow

follow changeset history, or file history across copies and renames

--follow-first

only follow the first parent of merge changesets

-d, --date

show revisions matching date spec

-C, --copies

show copied files

-k, --keyword

do case-insensitive search for a keyword

-r, --rev

show the specified revision or range

--removed

include revisions where files were removed

-m, --only-merges

-u, --user

revisions committed by user

-b, --only-branch

show only changesets within the given named branch

-P, --prune

do not display revision or any of its ancestors

-p, --patch

show patch

-g, --git

use git extended diff format

-l, --limit

limit number of changes displayed

-M, --no-merges

do not show merges

--style

display using template map file

--template

display with template

-I, --include

include names matching the given patterns

-X, --exclude

exclude names matching the given patterns

aliases: history
manifest [-r REV]
Print a list of version controlled files for the given revision. If no revision is given, the first parent of the working directory is used, or the null revision if no revision is checked out.

With -v, print file permissions, symlink and executable bits. With --debug, print file revision hashes.

options:

-r, --rev

revision to display

merge [-f] [[-r] REV]
The current working directory is updated with all changes made in the requested revision since the last common predecessor revision.

Files that changed between either parent are marked as changed for the next commit and a commit must be performed before any further updates to the repository are allowed. The next commit will have two parents.

If no revision is specified, the working directory's parent is a head revision, and the current branch contains exactly one other head, the other head is merged with by default. Otherwise, an explicit revision with which to merge with must be provided.

options:

-f, --force

force a merge with outstanding changes

-r, --rev

revision to merge

-P, --preview

review revisions to merge (no merge is performed)

outgoing [-M] [-p] [-n] [-f] [-r REV]... [DEST]
Show changesets not found in the specified destination repository or the default push location. These are the changesets that would be pushed if a push was requested.

See pull for valid destination format details.

options:

-f, --force

run even when remote repository is unrelated

-r, --rev

a specific revision up to which you would like to push

-n, --newest-first

show newest record first

-p, --patch

show patch

-g, --git

use git extended diff format

-l, --limit

limit number of changes displayed

-M, --no-merges

do not show merges

--style

display using template map file

--template

display with template

-e, --ssh

specify ssh command to use

--remotecmd

specify hg command to run on the remote side

aliases: out
parents [-r REV] [FILE]
Print the working directory's parent revisions. If a revision is given via -r/--rev, the parent of that revision will be printed. If a file argument is given, the revision in which the file was last changed (before the working directory revision or the argument to --rev if given) is printed.

options:

-r, --rev

show parents from the specified revision

--style

display using template map file

--template

display with template

paths [NAME]
Show definition of symbolic path name NAME. If no name is given, show definition of all available names.

Path names are defined in the [paths] section of /etc/mercurial/hgrc and $HOME/.hgrc. If run inside a repository, .hg/hgrc is used, too.

See 'hg help urls' for more information.

pull [-u] [-f] [-r REV]... [-e CMD] [--remotecmd CMD] [SOURCE]
Pull changes from a remote repository to a local one.

This finds all changes from the repository at the specified path or URL and adds them to a local repository (the current one unless -R is specified). By default, this does not update the copy of the project in the working directory.

Use hg incoming if you want to see what would have been added by a pull at the time you issued this command. If you then decide to added those changes to the repository, you should use pull -r X where X is the last changeset listed by hg incoming.

If SOURCE is omitted, the 'default' path will be used. See 'hg help urls' for more information.

options:

-u, --update

update to new tip if changesets were pulled

-f, --force

run even when remote repository is unrelated

-r, --rev

a specific remote revision up to which you would like to pull

-e, --ssh

specify ssh command to use

--remotecmd

specify hg command to run on the remote side

push [-f] [-r REV]... [-e CMD] [--remotecmd CMD] [DEST]
Push changes from the local repository to the given destination.

This is the symmetrical operation for pull. It moves changes from the current repository to a different one. If the destination is local this is identical to a pull in that directory from the current one.

By default, push will refuse to run if it detects the result would increase the number of remote heads. This generally indicates the user forgot to pull and merge before pushing.

If -r/--rev is used, the named revision and all its ancestors will be pushed to the remote repository.

Please see 'hg help urls' for important details about ssh:// URLs. If DESTINATION is omitted, a default path will be used.

options:

-f, --force

force push

-r, --rev

a specific revision up to which you would like to push

-e, --ssh

specify ssh command to use

--remotecmd

specify hg command to run on the remote side

recover
Recover from an interrupted commit or pull.

This command tries to fix the repository status after an interrupted operation. It should only be necessary when Mercurial suggests it.

remove [OPTION]... FILE...
Schedule the indicated files for removal from the repository.

This only removes files from the current branch, not from the entire project history. -A/--after can be used to remove only files that have already been deleted, -f/--force can be used to force deletion, and -Af can be used to remove files from the next revision without deleting them from the working directory.

The following table details the behavior of remove for different file states (columns) and option combinations (rows). The file states are Added [A], Clean [C], Modified [M] and Missing [!] (as reported by hg status). The actions are Warn, Remove (from branch) and Delete (from disk):

 A C M ! none W RD W R -f R RD RD R -A W W W R -Af R R R R
This command schedules the files to be removed at the next commit. To undo a remove before that, see hg revert.

options:

-A, --after

record delete for missing files

-f, --force

remove (and delete) file even if added or modified

-I, --include

include names matching the given patterns

-X, --exclude

exclude names matching the given patterns

aliases: rm
rename [OPTION]... SOURCE... DEST
Mark dest as copies of sources; mark sources for deletion. If dest is a directory, copies are put in that directory. If dest is a file, there can only be one source.

By default, this command copies the contents of files as they exist in the working directory. If invoked with -A/--after, the operation is recorded, but no copying is performed.

This command takes effect at the next commit. To undo a rename before that, see hg revert.

options:

-A, --after

record a rename that has already occurred

-f, --force

forcibly copy over an existing managed file

-I, --include

include names matching the given patterns

-X, --exclude

exclude names matching the given patterns

-n, --dry-run

do not perform actions, just print output

aliases: mv
resolve [OPTION]... [FILE]...
This command can cleanly retry unresolved file merges using file revisions preserved from the last update or merge.

If a conflict is resolved manually, please note that the changes will be overwritten if the merge is retried with resolve. The -m/--mark switch should be used to mark the file as resolved.

You can specify a set of files to operate on, or use the -a/-all switch to select all unresolved files.

This command also allows listing resolved files and manually indicating whether or not files are resolved. All files must be marked as resolved before a commit is permitted.

The codes used to show the status of files are:

U = unresolved R = resolved
options:
-a, --all

select all unresolved files

-l, --list

list state of files needing merge

-m, --mark

mark files as resolved

-u, --unmark

unmark files as resolved

-n, --no-status

hide status prefix

-I, --include

include names matching the given patterns

-X, --exclude

exclude names matching the given patterns

revert [OPTION]... [-r REV] [NAME]...
(Use update -r to check out earlier revisions, revert does not change the working directory parents.)

With no revision specified, revert the named files or directories to the contents they had in the parent of the working directory. This restores the contents of the affected files to an unmodified state and unschedules adds, removes, copies, and renames. If the working directory has two parents, you must explicitly specify the revision to revert to.

Using the -r/--rev option, revert the given files or directories to their contents as of a specific revision. This can be helpful to "roll back" some or all of an earlier change. See 'hg help dates' for a list of formats valid for -d/--date.

Revert modifies the working directory. It does not commit any changes, or change the parent of the working directory. If you revert to a revision other than the parent of the working directory, the reverted files will thus appear modified afterwards.

If a file has been deleted, it is restored. If the executable mode of a file was changed, it is reset.

If names are given, all files matching the names are reverted. If no arguments are given, no files are reverted.

Modified files are saved with a .orig suffix before reverting. To disable these backups, use --no-backup.

options:

-a, --all

revert all changes when no arguments given

-d, --date

tipmost revision matching date

-r, --rev

revision to revert to

--no-backup

do not save backup copies of files

-I, --include

include names matching the given patterns

-X, --exclude

exclude names matching the given patterns

-n, --dry-run

do not perform actions, just print output

rollback
This command should be used with care. There is only one level of rollback, and there is no way to undo a rollback. It will also restore the dirstate at the time of the last transaction, losing any dirstate changes since that time. This command does not alter the working directory.

Transactions are used to encapsulate the effects of all commands that create new changesets or propagate existing changesets into a repository. For example, the following commands are transactional, and their effects can be rolled back:

commit import pull push (with this repository as destination) unbundle
This command is not intended for use on public repositories. Once changes are visible for pull by other users, rolling a transaction back locally is ineffective (someone else may already have pulled the changes). Furthermore, a race is possible with readers of the repository; for example an in-progress pull from the repository may fail if a rollback is performed.
root
Print the root directory of the current repository.
serve [OPTION]...
Start a local HTTP repository browser and pull server.

By default, the server logs accesses to stdout and errors to stderr. Use the -A/--accesslog and -E/--errorlog options to log to files.

options:

-A, --accesslog

name of access log file to write to

-d, --daemon

run server in background

--daemon-pipefds

used internally by daemon mode

-E, --errorlog

name of error log file to write to

-p, --port

port to listen on (default: 8000)

-a, --address

address to listen on (default: all interfaces)

--prefix

prefix path to serve from (default: server root)

-n, --name

name to show in web pages (default: working directory)

--webdir-conf

name of the webdir config file (serve more than one repository)

--pid-file

name of file to write process ID to

--stdio

for remote clients

-t, --templates

web templates to use

--style

template style to use

-6, --ipv6

use IPv6 in addition to IPv4

--certificate

SSL certificate file

showconfig [-u] [NAME]...
With no arguments, print names and values of all config items.

With one argument of the form section.name, print just the value of that config item.

With multiple arguments, print names and values of all config items with matching section names.

With --debug, the source (filename and line number) is printed for each config item.

options:

-u, --untrusted

show untrusted configuration options

aliases: debugconfig
status [OPTION]... [FILE]...
Show status of files in the repository. If names are given, only files that match are shown. Files that are clean or ignored or the source of a copy/move operation, are not listed unless -c/--clean, -i/--ignored, -C/--copies or -A/--all are given. Unless options described with "show only ..." are given, the options -mardu are used.

Option -q/--quiet hides untracked (unknown and ignored) files unless explicitly requested with -u/--unknown or -i/--ignored.

NOTE: status may appear to disagree with diff if permissions have changed or a merge has occurred. The standard diff format does not report permission changes and diff only reports changes relative to one merge parent.

If one revision is given, it is used as the base revision. If two revisions are given, the differences between them are shown.

The codes used to show the status of files are:

M = modified A = added R = removed C = clean ! = missing (deleted by non-hg command, but still tracked) ? = not tracked I = ignored = origin of the previous file listed as A (added)
options:
-A, --all

show status of all files

-m, --modified

show only modified files

-a, --added

show only added files

-r, --removed

show only removed files

-d, --deleted

show only deleted (but tracked) files

-c, --clean

show only files without changes

-u, --unknown

show only unknown (not tracked) files

-i, --ignored

show only ignored files

-n, --no-status

hide status prefix

-C, --copies

show source of copied files

-0, --print0

end filenames with NUL, for use with xargs

--rev

show difference from revision

-I, --include

include names matching the given patterns

-X, --exclude

exclude names matching the given patterns

aliases: st
summary [--remote]
This generates a brief summary of the working directory state, including parents, branch, commit status, and available updates.

With the --remote option, this will check the default paths for incoming and outgoing changes. This can be time-consuming.

options:

--remote

check for push and pull

aliases: sum
tag [-l] [-m TEXT] [-d DATE] [-u USER] [-r REV] NAME...
Name a particular revision using <name>.

Tags are used to name particular revisions of the repository and are very useful to compare different revisions, to go back to significant earlier versions or to mark branch points as releases, etc.

If no revision is given, the parent of the working directory is used, or tip if no revision is checked out.

To facilitate version control, distribution, and merging of tags, they are stored as a file named ".hgtags" which is managed similarly to other project files and can be hand-edited if necessary. The file '.hg/localtags' is used for local tags (not shared among repositories).

See 'hg help dates' for a list of formats valid for -d/--date.

options:

-f, --force

replace existing tag

-l, --local

make the tag local

-r, --rev

revision to tag

--remove

remove a tag

-m, --message

use <text> as commit message

-d, --date

record datecode as commit date

-u, --user

record the specified user as committer

tags
This lists both regular and local tags. When the -v/--verbose switch is used, a third column "local" is printed for local tags.
tip [-p]
The tip revision (usually just called the tip) is the changeset most recently added to the repository (and therefore the most recently changed head).

If you have just made a commit, that commit will be the tip. If you have just pulled changes from another repository, the tip of that repository becomes the current tip. The "tip" tag is special and cannot be renamed or assigned to a different changeset.

options:

-p, --patch

show patch

-g, --git

use git extended diff format

--style

display using template map file

--template

display with template

unbundle [-u] FILE...
Apply one or more compressed changegroup files generated by the bundle command.

options:

-u, --update

update to new tip if changesets were unbundled

update [-c] [-C] [-d DATE] [[-r] REV]
Update the repository's working directory to the specified changeset.

If no changeset is specified, attempt to update to the head of the current branch. If this head is a descendant of the working directory's parent, update to it, otherwise abort.

The following rules apply when the working directory contains uncommitted changes:

1.

If neither -c/--check nor -C/--clean is specified, and if the requested changeset is an ancestor or descendant of the working directory's parent, the uncommitted changes are merged into the requested changeset and the merged result is left uncommitted. If the requested changeset is not an ancestor or descendant (that is, it is on another branch), the update is aborted and the uncommitted changes are preserved.

2.

With the -c/--check option, the update is aborted and the uncommitted changes are preserved.

3.

With the -C/--clean option, uncommitted changes are discarded and the working directory is updated to the requested changeset.

Use null as the changeset to remove the working directory (like 'hg clone -U').

If you want to update just one file to an older changeset, use 'hg revert'.

See 'hg help dates' for a list of formats valid for -d/--date.

options:

-C, --clean

discard uncommitted changes (no backup)

-c, --check

check for uncommitted changes

-d, --date

tipmost revision matching date

-r, --rev

revision

aliases: up checkout co
verify
Verify the integrity of the current repository.

This will perform an extensive check of the repository's integrity, validating the hashes and checksums of each entry in the changelog, manifest, and tracked files, as well as the integrity of their crosslinks and indices.

version
output version and copyright information

Mercurial reads configuration data from several files, if they exist. Below we list the most specific file first.

On Windows, these configuration files are read:

<repo>\.hg\hgrc

%USERPROFILE%\.hgrc

%USERPROFILE%\Mercurial.ini

%HOME%\.hgrc

%HOME%\Mercurial.ini

C:\Mercurial\Mercurial.ini

HKEY_LOCAL_MACHINE\SOFTWARE\Mercurial

<install-dir>\Mercurial.ini

On Unix, these files are read:
<repo>/.hg/hgrc

$HOME/.hgrc

/etc/mercurial/hgrc

/etc/mercurial/hgrc.d/*.rc

<install-root>/etc/mercurial/hgrc

<install-root>/etc/mercurial/hgrc.d/*.rc

The configuration files for Mercurial use a simple ini-file format. A configuration file consists of sections, led by a [section] header and followed by name = value entries:
[ui] username = Firstname Lastname <firstname.lastname@example.net> verbose = True
This above entries will be referred to as ui.username and ui.verbose, respectively. Please see the hgrc man page for a full description of the possible configuration values:
• on Unix-like systems: man hgrc

• online: http://www.selenic.com/mercurial/hgrc.5.html

Some commands allow the user to specify a date, e.g.:

• backout, commit, import, tag: Specify the commit date.

• log, revert, update: Select revision(s) by date.

Many date formats are valid. Here are some examples:
"Wed Dec 6 13:18:29 2006" (local timezone assumed) "Dec 6 13:18 -0600" (year assumed, time offset provided) "Dec 6 13:18 UTC" (UTC and GMT are aliases for +0000) "Dec 6" (midnight) "13:18" (today assumed) "3:39" (3:39AM assumed) "3:39pm" (15:39) "2006-12-06 13:18:29" (ISO 8601 format) "2006-12-6 13:18" "2006-12-6" "12-6" "12/6" "12/6/6" (Dec 6 2006)
Lastly, there is Mercurial's internal format:
"1165432709 0" (Wed Dec 6 13:18:29 2006 UTC)
This is the internal representation format for dates. unixtime is the number of seconds since the epoch (1970-01-01 00:00 UTC). offset is the offset of the local timezone, in seconds west of UTC (negative if the timezone is east of UTC).

The log command also accepts date ranges:

"<{datetime}" - at or before a given date/time ">{datetime}" - on or after a given date/time "{datetime} to {datetime}" - a date range, inclusive "-{days}" - within a given number of days of today

Mercurial accepts several notations for identifying one or more files at a time.

By default, Mercurial treats filenames as shell-style extended glob patterns.

Alternate pattern notations must be specified explicitly.

To use a plain path name without any pattern matching, start it with path:. These path names must completely match starting at the current repository root.

To use an extended glob, start a name with glob:. Globs are rooted at the current directory; a glob such as *.c will only match files in the current directory ending with .c.

The supported glob syntax extensions are ** to match any string across path separators and {a,b} to mean "a or b".

To use a Perl/Python regular expression, start a name with re:. Regexp pattern matching is anchored at the root of the repository.

Plain examples:

path:foo/bar a name bar in a directory named foo in the root of the repository path:path:name a file or directory named "path:name"
Glob examples:
glob:*.c any name ending in ".c" in the current directory *.c any name ending in ".c" in the current directory **.c any name ending in ".c" in any subdirectory of the current directory including itself. foo/*.c any name ending in ".c" in the directory foo foo/**.c any name ending in ".c" in any subdirectory of foo including itself.
Regexp examples:
re:.*\.c$ any name ending in ".c", anywhere in the repository

HG

Path to the 'hg' executable, automatically passed when running hooks, extensions or external tools. If unset or empty, this is the hg executable's name if it's frozen, or an executable named 'hg' (with %PATHEXT% [defaulting to COM/EXE/BAT/CMD] extensions on Windows) is searched.

HGEDITOR
This is the name of the editor to run when committing. See EDITOR.

(deprecated, use .hgrc)

HGENCODING
This overrides the default locale setting detected by Mercurial. This setting is used to convert data including usernames, changeset descriptions, tag names, and branches. This setting can be overridden with the --encoding command-line option.
HGENCODINGMODE
This sets Mercurial's behavior for handling unknown characters while transcoding user input. The default is "strict", which causes Mercurial to abort if it can't map a character. Other settings include "replace", which replaces unknown characters, and "ignore", which drops them. This setting can be overridden with the --encodingmode command-line option.
HGMERGE
An executable to use for resolving merge conflicts. The program will be executed with three arguments: local file, remote file, ancestor file.

(deprecated, use .hgrc)

HGRCPATH
A list of files or directories to search for hgrc files. Item separator is ":" on Unix, ";" on Windows. If HGRCPATH is not set, platform default search path is used. If empty, only the .hg/hgrc from the current repository is read.

For each element in HGRCPATH:

• if it's a directory, all files ending with .rc are added

• otherwise, the file itself will be added

HGUSER

This is the string used as the author of a commit. If

not set, available values will be considered in this order:
• HGUSER (deprecated)

• hgrc files from the HGRCPATH

• EMAIL

• interactive prompt

• LOGNAME (with @hostname appended)

(deprecated, use .hgrc)
EMAIL

May be used as the author of a commit; see HGUSER.

LOGNAME
May be used as the author of a commit; see HGUSER.
VISUAL

This is the name of the editor to use when committing. See EDITOR.

EDITOR

Sometimes Mercurial needs to open a text file in an editor for a user to modify, for example when writing commit messages. The editor it uses is determined by looking at the environment variables HGEDITOR, VISUAL and EDITOR, in that order. The first non-empty one is chosen. If all of them are empty, the editor defaults to 'vi'.

PYTHONPATH
This is used by Python to find imported modules and may need to be set appropriately if this Mercurial is not installed system-wide.

Mercurial supports several ways to specify individual revisions.

A plain integer is treated as a revision number. Negative integers are treated as sequential offsets from the tip, with -1 denoting the tip, -2 denoting the revision prior to the tip, and so forth.

A 40-digit hexadecimal string is treated as a unique revision identifier.

A hexadecimal string less than 40 characters long is treated as a unique revision identifier and is referred to as a short-form identifier. A short-form identifier is only valid if it is the prefix of exactly one full-length identifier.

Any other string is treated as a tag or branch name. A tag name is a symbolic name associated with a revision identifier. A branch name denotes the tipmost revision of that branch. Tag and branch names must not contain the ":" character.

The reserved name "tip" is a special tag that always identifies the most recent revision.

The reserved name "null" indicates the null revision. This is the revision of an empty repository, and the parent of revision 0.

The reserved name "." indicates the working directory parent. If no working directory is checked out, it is equivalent to null. If an uncommitted merge is in progress, "." is the revision of the first parent.

When Mercurial accepts more than one revision, they may be specified individually, or provided as a topologically continuous range, separated by the ":" character.

The syntax of range notation is [BEGIN]:[END], where BEGIN and END are revision identifiers. Both BEGIN and END are optional. If BEGIN is not specified, it defaults to revision number 0. If END is not specified, it defaults to the tip. The range ":" thus means "all revisions".

If BEGIN is greater than END, revisions are treated in reverse order.

A range acts as a closed interval. This means that a range of 3:5 gives 3, 4 and 5. Similarly, a range of 9:6 gives 9, 8, 7, and 6.

Mercurial's default format for showing changes between two versions of a file is compatible with the unified format of GNU diff, which can be used by GNU patch and many other standard tools.

While this standard format is often enough, it does not encode the following information:

• executable status and other permission bits

• copy or rename information

• changes in binary files

• creation or deletion of empty files

Mercurial also supports the extended diff format from the git VCS which addresses these limitations. The git diff format is not produced by default because a few widespread tools still do not understand this format.

This means that when generating diffs from a Mercurial repository (e.g. with "hg export"), you should be careful about things like file copies and renames or other things mentioned above, because when applying a standard diff to a different repository, this extra information is lost. Mercurial's internal operations (like push and pull) are not affected by this, because they use an internal binary format for communicating changes.

To make Mercurial produce the git extended diff format, use the --git option available for many commands, or set 'git = True' in the [diff] section of your hgrc. You do not need to set this option when importing diffs in this format or using them in the mq extension.

Mercurial allows you to customize output of commands through templates. You can either pass in a template from the command line, via the --template option, or select an existing template-style (--style).

You can customize output for any "log-like" command: log, outgoing, incoming, tip, parents, heads and glog.

Three styles are packaged with Mercurial: default (the style used when no explicit preference is passed), compact and changelog. Usage:

$ hg log -r1 --style changelog
A template is a piece of text, with markup to invoke variable expansion:
$ hg log -r1 --template "{node}\n" b56ce7b07c52de7d5fd79fb89701ea538af65746
Strings in curly braces are called keywords. The availability of keywords depends on the exact context of the templater. These keywords are usually available for templating a log-like command:
author

String. The unmodified author of the changeset.

branches
String. The name of the branch on which the changeset was committed. Will be empty if the branch name was default.
date

Date information. The date when the changeset was committed.

desc

String. The text of the changeset description.

diffstat
String. Statistics of changes with the following format: "modified files: +added/-removed lines"
files

List of strings. All files modified, added, or removed by this changeset.

file_adds
List of strings. Files added by this changeset.
file_mods
List of strings. Files modified by this changeset.
file_dels
List of strings. Files removed by this changeset.
node

String. The changeset identification hash, as a 40-character hexadecimal string.

parents
List of strings. The parents of the changeset.
rev

Integer. The repository-local changeset revision number.

tags

List of strings. Any tags associated with the changeset.

latesttag
String. Most recent global tag in the ancestors of this changeset.
latesttagdistance
Integer. Longest path to the latest tag.
The "date" keyword does not produce human-readable output. If you want to use a date in your output, you can use a filter to process it. Filters are functions which return a string based on the input variable. You can also use a chain of filters to get the desired output:
$ hg tip --template "{date|isodate}\n" 2008-08-21 18:22 +0000
List of filters:
addbreaks
Any text. Add an XHTML "<br />" tag before the end of every line except the last.
age

Date. Returns a human-readable date/time difference between the given date/time and the current date/time.

basename
Any text. Treats the text as a path, and returns the last component of the path after splitting by the path separator (ignoring trailing separators). For example, "foo/bar/baz" becomes "baz" and "foo/bar//" becomes "bar".
stripdir
Treat the text as path and strip a directory level, if possible. For example, "foo" and "foo/bar" becomes "foo".
date

Date. Returns a date in a Unix date format, including the timezone: "Mon Sep 04 15:13:13 2006 0700".

domain

Any text. Finds the first string that looks like an email address, and extracts just the domain component. Example: User <user@example.com> becomes example.com.

email

Any text. Extracts the first string that looks like an email address. Example: User <user@example.com> becomes user@example.com.

escape

Any text. Replaces the special XML/XHTML characters "&", "<" and ">" with XML entities.

"1157407993 25200" (Unix timestamp, timezone offset).
isodate
Date. Returns the date in ISO 8601 format: "2009-08-18 13:00 +0200".
isodatesec
Date. Returns the date in ISO 8601 format, including seconds: "2009-08-18 13:00:13 +0200". See also the rfc3339date filter.

urlescape
Any text. Escapes all "special" characters. For example, "foo bar" becomes "foo%20bar".
user

Any text. Returns the user portion of an email address.

Valid URLs are of the form:

local/filesystem/path[#revision] file://local/filesystem/path[#revision] http://[user[:pass]@]host[:port]/[path][#revision] https://[user[:pass]@]host[:port]/[path][#revision] ssh://[user[:pass]@]host[:port]/[path][#revision]
Paths in the local filesystem can either point to Mercurial repositories or to bundle files (as created by 'hg bundle' or 'hg incoming --bundle').

An optional identifier after # indicates a particular branch, tag, or changeset to use from the remote repository. See also 'hg help revisions'.

Some features, such as pushing to http:// and https:// URLs are only possible if the feature is explicitly enabled on the remote Mercurial server.

Some notes about using SSH with Mercurial:

• SSH requires an accessible shell account on the destination machine and a copy of hg in the remote path or specified with as remotecmd.

• path is relative to the remote user's home directory by default. Use an extra slash at the start of a path to specify an absolute path:

ssh://example.com//tmp/repository
• Mercurial doesn't use its own compression via SSH; the right thing to do is to configure it in your ~/.ssh/config, e.g.:
Host *.mylocalnetwork.example.com Compression no Host * Compression yes
Alternatively specify "ssh -C" as your ssh command in your hgrc or with the --ssh command line option.
These URLs can all be stored in your hgrc with path aliases under the [paths] section like so:
[paths] alias1 = URL1 alias2 = URL2 ...
You can then use the alias for any command that uses a URL (for example 'hg pull alias1' will be treated as 'hg pull URL1').

Two path aliases are special because they are used as defaults when you do not provide the URL to a command:

default:
When you create a repository with hg clone, the clone command saves the location of the source repository as the new repository's 'default' path. This is then used when you omit path from push- and pull-like commands (including incoming and outgoing).
default-push:
The push command will look for a path named 'default-push', and prefer it over 'default' if both are defined.

Mercurial has the ability to add new features through the use of extensions. Extensions may add new commands, add options to existing commands, change the default behavior of commands, or implement hooks.

Extensions are not loaded by default for a variety of reasons: they can increase startup overhead; they may be meant for advanced usage only; they may provide potentially dangerous abilities (such as letting you destroy or modify history); they might not be ready for prime time; or they may alter some usual behaviors of stock Mercurial. It is thus up to the user to activate extensions as needed.

To enable the "foo" extension, either shipped with Mercurial or in the Python search path, create an entry for it in your hgrc, like this:

[extensions] foo =
You may also specify the full path to an extension:
[extensions] myfeature = ~/.hgext/myfeature.py
To explicitly disable an extension enabled in an hgrc of broader scope, prepend its path with !:
[extensions] # disabling extension bar residing in /path/to/extension/bar.py hgext.bar = !/path/to/extension/bar.py # ditto, but no path was supplied for extension baz hgext.baz = !

.hgignore

This file contains regular expressions (one per line) that describe file names that should be ignored by hg. For details, see hgignore(5).
.hgtags
This file contains changeset hash values and text tag names (one of each separated by spaces) that correspond to tagged versions of the repository contents.
/etc/mercurial/hgrc, $HOME/.hgrc, .hg/hgrc
This file contains defaults and configuration. Values in .hg/hgrc override those in $HOME/.hgrc, and these override settings made in the global /etc/mercurial/hgrc configuration. See hgrc(5) for details of the contents and format of these files.
Some commands (e.g. revert) produce backup files ending in .orig, if the .orig file already exists and is not tracked by Mercurial, it will be overwritten.

Probably lots, please post them to the mailing list (see Resources below) when you find them.
