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 tempnam(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)     The directory specified by the environment variable TMPDIR, if it exists.

       b)     The directory specified by the --directory argument, if given.

       c)     The directory /tmp.

       See tempnam(3) for the actual steps involved in directory selection.

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

       -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.

       -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
              ignored if this option is given.

       --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.

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