pwhich - Pure Perl implementation of which
$ pwhich perl
$ pwhich -a perl # print all matches
$ pwhich perl perldoc ... # look for multiple programs
$ pwhich -a perl perldoc ...
$ pwhich -s perl # silent mode
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.
$ pwhich [-a] [-s] [-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.
No output, just return 0 if any of the executables are found, or 1 if none are found.
Prints version (of File::Which) and copyright notice and exits.
Bugs should be reported via the GitHub issue tracker https://github.com/uperl/App-pwhich/issues For other issues, contact the maintainer.
Perl API for pwhich
Guts of this script.
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.
