NAME
tempfile - create a temporary file in a safe manner
SYNOPSIS
tempfile [-d DIR] [-p STRING] [-s STRING] [-m MODE] [-n FILE] [--directory=DIR] [--prefix=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, --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.
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 cannot 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
