.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This command deals with shell \f(CW$PATH\fR variables. It can find a program
through one or more filenames given by one or more \fIstr\fR arguments.
It prints the absolute filesystem path to the program displayed on
\&\f(CW\*(C`stdout\*(C'\fR plus an exit code of 0 if it was really found.
.SH "OPTIONS"
.IX Header "OPTIONS"
The following command line options are available.
.IP "\fB\-s\fR, \fB\-\-suppress\fR" 4
.IX Item "-s, --suppress"
Suppress output. Useful to only test whether a program exists with the
help of the return code.
.IP "\fB\-r\fR, \fB\-\-reverse\fR" 4
.IX Item "-r, --reverse"
Transform a forward path to a subdirectory into a reverse path.
.IP "\fB\-d\fR, \fB\-\-dirname\fR" 4
.IX Item "-d, --dirname"
Output the directory name of \fIstr\fR.
.IP "\fB\-b\fR, \fB\-\-basename\fR" 4
.IX Item "-b, --basename"
Output the base name of \fIstr\fR.
.IP "\fB\-m\fR, \fB\-\-magic\fR" 4
.IX Item "-m, --magic"
Enable advanced magic search for "\f(CW\*(C`perl\*(C'\fR\*(L" and \*(R"\f(CW\*(C`cpp\*(C'\fR".
.IP "\fB\-p\fR, \fB\-\-path\fR \fIpath\fR" 4
.IX Item "-p, --path path"
Search in \fIpath\fR. Default is to search in \f(CW$PATH\fR.

The \fB\s-1GNU\s0 shtool\fR \fBpath\fR command was originally written by Ralf S.
Engelschall <rse@engelschall.com> in 1998 for \fBApache\fR. It was
later taken over into \fB\s-1GNU\s0 shtool\fR.
