NAME

Whence - Perl implementation/extension of ksh 'whence' builtin

SYNOPSIS

    Whence foo
    Whence '?sh'
    Whence '*stat'
    Whence -f foo\*

DESCRIPTION

This is a Perl implementation of the ksh whence builtin, similar to csh which or bash type -p. It differs from these in two ways: (1) it finds all occurrences of its arguments on PATH rather than just the first and (2) it treats its arguments as patterns, such that Whence cat* will return all commands that start with cat rather than looking for a literal 'cat*'.
