Generate a unique temporary filename for use in a script. The filename is based on the specified template, which may be any filename with at least six Xs appended (e.g., /tmp/mytemp.XXXXXX). mktemp replaces the Xs with the current process number and/or a unique letter combination. The file is created with mode 0600 (unless -u is specified) and the filename is written to standard output.
Make a directory, not a file.
Fail silently in case of error. Useful to prevent error output from being sent to standard error.
Operate in “unsafe” mode and unlink the temporary file before mktemp exits. Use of this option is not recommended.
