NAME
       shtool-path - GNU shtool command dealing with shell path variables

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

DESCRIPTION
       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.

OPTIONS
       The following command line options are available.

       -s, --suppress
           Suppress 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.

EXAMPLE
        #   shell script
        awk=`shtool path -p "${PATH}:." gawk nawk awk`
        perl=`shtool path -m perl`
        cpp=`shtool path -m cpp`

HISTORY
       The GNU shtool path command was originally written by Ralf S.
       Engelschall <rse@engelschall.com> in 1998 for Apache. It was later
       taken over into GNU shtool.
