usage: mktemp [-dqu] [-p DIR] [TEMPLATE]
Safely create a new file "DIR/TEMPLATE" and print its name.
-d Create directory instead of file (--directory)
-p Put new file in DIR (--tmpdir)
-q Quiet, no error messages
-t Prepend $TMPDIR or /tmp if unset
-u Don't create anything, just print what would be created
Each X in TEMPLATE is replaced with a random printable character. The
default TEMPLATE is tmp.XXXXXXXXXX.
