shtool path - GNU shtool command dealing with shell path variables


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.

The GNU shtool path command was originally written by Ralf S. Engelschall <rse [at]> in 1998 for Apache. It was later taken over into GNU shtool.
