From fb2b22fce88d323727a49c760187c0470b78fa9a Mon Sep 17 00:00:00 2001
From: Alfred Wingate <parona@protonmail.com>
Date: Wed, 21 Jun 2023 11:35:04 +0300
Subject: [PATCH] Remove use of which, use command -v or built-ins instead
* which isn't a POSIX tool and some distributions have or are still
considering dropping it in favour of using commands included by
POSIX or shell built-ins.
* Used command built-in where applicable, but type and whence for bash
and zsh respectively in virtualenvwrapper_verify_resource to preserve
previous behaviour with which when programs also have built-ins
with the same name. command -v outputs just the name and not the path
in those cases.
