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] [--direc- tory=DIR] [--prefix=STRING] [--suffix=STRING] [--mode=MODE] [--name=FILE] [--help] [--version] DESCRIPTION tempfile creates a temporary file in a safe manner. It uses mk- stemps(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 appropri- ate. 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 ignored 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 success- fully. 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 parti- tions. tempfile cannot make temporary directories. tempfile is depre- cated; you should use mktemp(1) instead. EXAMPLE #!/bin/sh #[...] t=$(tempfile) || exit trap "rm -f -- '$t'" EXIT #[...] rm -f -- "$t" trap - EXIT exit SEE ALSO tempnam(3), mktemp(1) Debian 27 Jun 2012 TEMPFILE(1)
