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.
