Subject: [PATCH] git-submodule.sh: avoid "test <cond> -a/-o <cond>"
Date: Tue, 10 Jun 2014 05:28:33 -0700 [thread overview]
Message-ID: <1402403313-22468-1-git-send-email-gitter.spiros@gmail.com> (raw)
The construct is error-prone; "test" being built-in in most modern
shells, the reason to avoid "test <cond> && test <cond>" spawning
one extra process by using a single "test <cond> -a <cond>" no
longer exists.
