mktemp

Runs on:

QNX Neutrino

Options:

-d

Create a directory instead of a file.

-p prefix

Use the specified directory as a prefix when creating the temporary file. This prefix is overridden if the TMPDIR environment variable is set. The option implies -t.

-q

Don't print anything, even error messages.

-t

Create the temporary file in a temporary directory. The process for selecting a temporary directory is as follows:

1. the TMPDIR environment variable, if set
2. the directory specified with the -p option.
3. /tmp

In this mode, the template (if specified) should be a directory component (as opposed to a full path) and thus shouldn't contain any forward slashes.

-u

Unlink the temporary file before exiting.

Note: This behavior is considered unsafe, and its use isn't encouraged.

-V

Print the version of the utility and then exit.

Description:

The mktemp utility creates a unique temporary file or directory. The template can be any filename with at least six X characters appended to it. The Xs are replaced with a unique combination of alphanumeric characters. If you don't specify a template, then mktemp uses tmp.XXXXXXXXXX, and the -t option is implied.

If mktemp successfully generates a unique name, it then opens the file or directory with read and write permission for the owner (unless you specify the -u option).

Exit status:

0

The file or directory was successfully created.

1

An error occurred.
