NAME

mktemp - create a temporary file or directory  

SYNOPSIS

mktemp [,OPTION/]... [,TEMPLATE/]  

DESCRIPTION

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.

X'tty: link https://www.gnu.org/software/coreutils/manual/coreutils.html#mktem-d'-d, --directoryX'tty: link'

create a directory, not a file

X'tty: link https://www.gnu.org/software/coreutils/manual/coreutils.html#mktem-u'-u, --dry-runX'tty: link'

do not create anything; merely print a name (unsafe)

X'tty: link https://www.gnu.org/software/coreutils/manual/coreutils.html#mktem-q'-q, --quietX'tty: link'

suppress diagnostics about file/dir-creation failure

X'tty: link https://www.gnu.org/software/coreutils/manual/coreutils.html#mktem-suffix'--suffix=SUFFX'tty: link'

append SUFF to TEMPLATE; SUFF must not contain a slash. This option is implied if TEMPLATE does not end in X

X'tty: link https://www.gnu.org/software/coreutils/manual/coreutils.html#mktem-p'-p DIR, --tmpdir[=,DIR]X'tty: link'/

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

X'tty: link https://www.gnu.org/software/coreutils/manual/coreutils.html#mktem-t'-tX'tty: link'

interpret TEMPLATE as a single file name component, relative to a directory: $TMPDIR, if set; else the directory specified via -p; else ,/tmp/ [deprecated]

X'tty: link https://www.gnu.org/software/coreutils/mktemp#mktem-help'--helpX'tty: link'

display this help and exit

X'tty: link https://www.gnu.org/software/coreutils/mktemp#mktem-version'--versionX'tty: link'

output version information and exit
