From 87154755d90ed60919cc5709e322b397701e4f58 Mon Sep 17 00:00:00 2001 From: Matthieu Baerts Date: Thu, 17 Feb 2022 19:03:10 -0800 Subject: [PATCH] selftests: mptcp: join: check for tools only if needed To allow showing the 'help' menu even if these tools are not available. While at it, also avoid launching the command then checking $?. Instead, the check is directly done in the 'if'.
