SYNOPSYS

tempfile [-d DIR? [-p STRING? [-m MODE? [-n FILE? [--directory=DIR? [--prefix=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 to place the file is searched for in the following order:

a)

The directory specified by the environment variable TMPDIR, if it is writable.

b)

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

c)

The directory /tmp.

Debian packages using tempfile in maintainer scripts must depend on debianutils __

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 succesfully.

--version

Print version information on standard output and exist succesfully.

RETURN VALUES

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

BUGS

Exclusive creation is not guaranteed when creating files on NFS partitions.
