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 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
