SYNOPSIS
shtool path [-s|--suppress] [-r|--reverse] [-d|--dirname]

DESCRIPTION
This command deals with shell $PATH variables. It can find a program

prints the absolute filesystem path to the program displayed on
"stdout" plus an exit code of 0 if it was really found.

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

cpp=`shtool path -m cpp`
revpath=`shtool path -r path/to/subdir`
HISTORY
The GNU shtool path command was originally written by Ralf S.
