NAME

pwhich - Pure Perl implementation of which

VERSION

version 1.17

SYNOPSIS

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

DESCRIPTION

"pwhich" is a comman-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] [-s] [-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.
-s: No output, just return 0 if any of the executables are found, or 1 if none are found.
-v: Prints version (of "File::Which") and copyright notice and exits.

SUPPORT

Bugs should be reported via the GitHub issue tracker <https://github.com/uperl/App-pwhich/issues> For other issues, contact the maintainer.

CAVEATS

This module does not know about buil-in shell commands, as the buil-in command "which" and "where" usually do.

This module is fully supported back to Perl 5.8.1. It may work on 5.8.0.

If you want these executables installed without the "p" prefix (useful on platforms like windows that do not have their own native which or where), set "PERL_APP_PWHICH_NO_PREFIX" to "no-prefix" during install of this module.
