SHTOOL-PATH.TMP(1)                   GNU Portable Shell Tool                   SHTOOL-PATH.TMP(1)

       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.

        #   shell script
        awk=`shtool path -p "${PATH}:." gawk nawk awk`
        perl=`shtool path -m perl`
        cpp=`shtool path -m cpp`
        revpath=`shtool path -r path/to/subdir`

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