From mboxrd@z Thu Jan 1 00:00:00 1970 From: Yotam Gigi Subject: [PATCH net-next/iproute v2 1/5] tc: bash-completion: Add the _from variant to _tc_one* funcs Date: Tue, 7 Feb 2017 15:50:48 +0200 Message-ID: <1486475452-39214-2-git-send-email-yotamg@mellanox.com> References: <1486475452-39214-1-git-send-email-yotamg@mellanox.com> Cc: Yotam Gigi To: netdev@vger.kernel.org, stephen@networkplumber.org, eladr@mellanox.com, idosch@mellanox.com, jiri@mellanox.com, jhs@mojatatu.com, mrv@mojatatu.com Return-path: Received: from mail-il-dmz.mellanox.com ([193.47.165.129]:38673 "EHLO mellanox.co.il" rhost-flags-OK-OK-OK-FAIL) by vger.kernel.org with ESMTP id S1754088AbdBGNsW (ORCPT ); Tue, 7 Feb 2017 08:48:22 -0500 In-Reply-To: <1486475452-39214-1-git-send-email-yotamg@mellanox.com> Sender: netdev-owner@vger.kernel.org List-ID: The _tc_one_of_list and _tc_once_attr functions simplfy the bash completion task by validating each attr exist only once on the command line. For example, for the command line: $ a b c d e and the call to _tc_once_attr with "a f g", the function will suggest "f g" as "a" existed in the command line in args 0. Add the _from variant to those functions, which allows having the command line option once from a specified index. In the previous example, calling _tc_once_attr with 4 and "a f g" will suggest "a f g".
