From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jesper Dangaard Brouer Subject: [net-next PATCH] net: Make it easier to parse /proc/net/dev contents. Date: Tue, 05 Jan 2010 16:50:52 +0100 Message-ID: <20100105155052.13309.1197.stgit@firesoul.comx.local> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Cc: Jesper Dangaard Brouer , netdev@vger.kernel.org To: "David S. Miller" Return-path: Received: from lanfw001a.cxnet.dk ([87.72.215.196]:49657 "EHLO lanfw001a.cxnet.dk" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1754126Ab0AEQXS (ORCPT ); Tue, 5 Jan 2010 11:23:18 -0500 Sender: netdev-owner@vger.kernel.org List-ID: The contents of /proc/net/dev is annoying to parse, because it changes whether there is a space after the "ethX:" or not. It depends upon the size of the "Receive bytes" counter, if the number is below 7 digits, then there is whitespaces else if the number is 8 digits or above there is no space between the ":" and the number. This patch changes the output to assure there is always a space between the ":" and the number. Given that all existing userspace application already need to handle the whitespaces, I see no breakage of existing tools.
