pwhich - Perl-only `which'
$ pwhich perl $ pwhich -a perl # print all matches $ pwhich perl perldoc ... # look for multiple programs $ pwhich -a perl perldoc ...
`pwhich' is a command-line utility program for finding paths to other programs based on the user's PATH. It is similar to the usually Unix tool `which', and tries to emulate its functionality, but is written purely in Perl (uses the module File::Which), so is portable.
PATH
File::Which
$ pwhich [-a] [-v] programname [programname ...]
The option -a will make pwhich print all matches found in the PATH variable instead of just the first one. Each match is printed on a separate line.
pwhich
Prints version (of File::Which) and copyright notice and exits.

This module purports to "check that a command is available", but does not provide any documentation on how you might use it.

Originated in modperl-2.0/lib/Apache/Build.pm. Changed for use in DocSet (for the mod_perl site) and Win32-awareness by me, with slight modifications by Stas Bekman, then extracted to create File::Which.
Version 0.04 had some significant platform-related changes, taken from the Perl Power Tools `which' implementation by Abigail with enhancements from Peter Prymmer. See http://www.perl.com/language/ppt/src/which/index.html for more information.
