tempfile - create a temporary file in a safe manner

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

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.

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

-d,--directoryDIR
              Place the file in DIR.

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

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

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

       -s,--suffixSTRING
              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.

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