-s, --suppress

Supress output. Useful to only test whether a program exists with the help of the return code.

-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 ""perl"" and ""cpp"".

-p, --path path

Search in path. Default is to search in $PATH.
