- -r, --reverse
- Transform a forward path to a subdirectory into a reverse path.
- -d, --dirname
- Output the directory name of str.
- -b, --basename
- Output the base name of str.
- -m, --magic
- Enable advanced magic search for "CWperl and CWcpp".
- -p, --path path
- Search in path. Default is to search in CW$PATH.
