shtool path [-s|--suppress] [-r|--reverse] [-d|--dirname] [-b|--basename] [-m|--magic] [-p|--path path] str [str ...]

This command deals with shell $PATH variables. It can find a program through one or more filenames given by one or more str arguments. It prints the absolute filesystem path to the program displayed on stdout plus an exit code of 0 if it was really found.

The following command line options are available.

-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.
