prename

renames multiple files

TLDR

Rename files using a Perl Common Regular Expression (substitute 'foo' with 'bar' wherever found)

>_ rename ['s/foo/bar/'] [*]
copy

Dry-run - display which renames would occur without performing them

>_ rename -n ['s/foo/bar/'] [*]
copy

Force renaming even if the operation would remove existing destination files

>_ rename -f ['s/foo/bar/'] [*]
copy

Convert filenames to lower case (use -f in case-insensitive filesystems to prevent "already exists" errors)

>_ rename 'y/A-Z/a-z/' [*]
copy

Replace whitespace with underscores

>_ rename 's/\s+/_/g' [*]
copy

SYNOPSIS

rename [ -v ] [ -n ] [ -f ] perlexpr [ files ]

DESCRIPTION

"rename" renames the filenames supplied according to the rule specified as the first argument. The perlexpr argument is a Perl expression which is expected to modify the $_ string in Perl for at least some of the filenames specified. If a given filename is not modified by the expression, it will not be renamed. If no filenames are given on the command line, filenames will be read via standard input.

For example, to rename all files matching "*.bak" to strip the extension, you might say

 rename 's/\.bak$//' *.bak 

To translate uppercase names to lower, you'd use

 rename 'y/A-Z/a-z/' * 

OPTIONS

-v, --verbose
Verbose: print names of files successfully renamed.
-n, --no-act
No Action: show what files would have been renamed.
-f, --force
Force: overwrite existing files.

ENVIRONMENT

No environment variables are used.

DIAGNOSTICS

If you give an invalid Perl expression you'll get a syntax error.

BUGS

The original "rename" did not check for the existence of target filenames, so had to be used with care. I hope I've fixed that (Robin Barker).
