TEMPFILE(1)                          General Commands Manual                          TEMPFILE(1)

NAME
       tempfile - create a temporary file in a safe manner

SYNOPSIS
       tempfile  [-d  DIR]  [-p STRING] [-s STRING] [-m MODE] [-n FILE] [--directory=DIR] [--pre-
       fix=STRING] [--suffix=STRING] [--mode=MODE] [--name=FILE] [--help] [--version]

DESCRIPTION
       tempfile creates a temporary file in a safe manner.  It uses  mkstemps(3)  to  choose  the
       name  and  opens  it  with O_RDWR | O_CREAT | O_EXCL.  The filename is printed on standard
       output.

       The directory in which to create the file might be searched for in this order:

       a) In case the environment variable TMPDIR exists and contains the name of an  appropriate
          directory, that is used.

       b) Otherwise, if the --directory argument is specified and appropriate, it is used.

       c) Otherwise, P_tmpdir (as defined in <stdio.h>) is used when appropriate.

       d) Finally an implementation-defined directory (/tmp) may be used.

OPTIONS
       -d, --directory DIR
              Place the file in DIR.

       -m, --mode MODE
              Open the file with MODE instead of 0600.

       -n, --name FILE
              Use  FILE  for  the name instead of tempnam(3).  The options -d, -p, and -s are ig-
              nored if this option is given.

       -p, --prefix STRING
              Use up to five letters of STRING to generate the name.

       -s, --suffix STRING
              Generate the file with STRING as the suffix.

       --help Print a usage message on standard output and exit successfully.

       --version
              Print version information on standard output and exit successfully.

RETURN VALUES
       An exit status of 0 means the temporary file was created  successfully.   Any  other  exit
       status indicates an error.

BUGS
       Exclusive creation is not guaranteed when creating files on NFS partitions.  tempfile can-
       not make temporary directories.  tempfile is deprecated; you should use mktemp(1) instead.

EXAMPLE
       #!/bin/sh
       #[...]
       t=$(tempfile) || exit
       trap "rm -f -- '$t'" EXIT
       #[...]
       rm -f -- "$t"
       trap - EXIT
       exit
