tempfile − create a temporary file in a safe manner
tempfile [−d DIR] [−p STRING] [−s STRING] [−m MODE] [−n FILE] [−−directory=DIR] [−−prefix=STRING] [−−suffix=STRING] [−−mode=MODE] [−−name=FILE] [−−help] [−−version]
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.
-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.
An exit status of 0 means the temporary file was created successfully. Any other exit status indicates an error.
Exclusive creation is not guaranteed when creating files on NFS partitions.
