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 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] [-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 built-in shell commands, as the built-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.
