Linux Command Library


create a temporary file or directory

- Create an empty temporary file and return the absolute path to it:

- Create a temporary directory and return the absolute path to it:
mktemp -d

- Create a temporary file with a specified suffix:
mktemp --suffix "[.txt]"

mktemp [,OPTION/]... [,TEMPLATE/]

Create a temporary file or directory, safely, and print its name. TEMPLATE must contain at least 3 consecutive 'X's in last component. If TEMPLATE is not specified, use tmp.XXXXXXXXXX, and --tmpdir is implied. Files are created u+rw, and directories u+rwx, minus umask restrictions.

-d, --directory
create a directory, not a file
-u, --dry-run
do not create anything; merely print a name (unsafe)
-q, --quiet
suppress diagnostics about file/dir-creation failure
append SUFF to TEMPLATE; SUFF must not contain a slash. This option is implied if TEMPLATE does not end in X
-p DIR, --tmpdir[=,DIR/]
interpret TEMPLATE relative to DIR; if DIR is not specified, use $TMPDIR if set, else ,/tmp/. With this option, TEMPLATE must not be an absolute name; unlike with -t, TEMPLATE may contain slashes, but mktemp creates only the final component
interpret TEMPLATE as a single file name component, relative to a directory: $TMPDIR, if set; else the directory specified via -p; else ,/tmp/ [deprecated]
display this help and exit
output version information and exit
