$SCRIPT -d directory [-n]

-d directory directory to be created.

-n never prompt when removing existing directory.

Attempts to safely create an empty directory. If -n is not
|
|
specified, the script will prompt before deleting any files
|
|
or directories. If -n is specified, it will not prompt.
|
|
|
|
The safety measures include refusing to run if run by user
|
|
root and by refusing to create directories unless there are
|
|
a subdirectory of /tmp or have at least two ancestor
|
|
directories... /grandparent/parent/child.

******************** WARNING ********************

This script will destroy existing directories and

their contents. It can potentially wipe out your
