/usr/bin/mktemp

Usage: /usr/bin/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
      --suffix=SUFF
         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
  -t
         interpret TEMPLATE as a single file name component,
         relative to a directory: $TMPDIR, if set;
         else the directory specified via -p; else /tmp [deprecated]
      --help
         display this help and exit
      --version
         output version information and exit
