NAME

pwhich - Perl-only `which'

SYNOPSIS

$ pwhich perl
$ pwhich -a perl          # print all matches
$ pwhich perl perldoc ... # look for multiple programs
$ pwhich -a perl perldoc ...

DESCRIPTION

The pwhich bundled with File-Which is deprecated It will be removed from File-Which, but not before April 30, 2015 Please install App::pwhich instead

`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.

Calling syntax

$ pwhich [-a] [-v] programname [programname ...]

Options

-a

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.

-v

Prints version (of File::Which) and copyright notice and exits.

SUPPORT

Bugs should be reported via the GitHub issue tracker

Guts of this script.

Comes with a can_run function with slightly different semantics that the traditional UNIX where. It will find executables in the current directory, even though the current directory is not searched for by default on Unix.

Devel::CheckBin

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.
