Message-Id: <1444935676-10068-1-git-send-email-phil@nwl.cc> Date: Thu, 15 Oct 2015 21:01:16 +0200 From: Phil Sutter <phil@....cc> To: Stephen Hemminger <shemming@...cade.com> Cc: netdev@...r.kernel.org Subject: [PATCH iproute2] ss: return -1 if an unrecognized option was given When getopt_long encounters an option which has not been registered, it returns '?'. React upon that and call usage() instead of help() so ss returns with a non-zero exit status.
