From be6bb51a9f6a60995e0069bfdd9e0611d78ae4c6 Mon Sep 17 00:00:00 2001 From: Alexander Kapshuk Date: Mon, 12 Oct 2015 21:39:57 +0300 Subject: ver_linux: net-tools, look for numerical input, not field number Rely on regex to find the version number, rather than rely on numerical input to be found in a particular input field. Proposed implementation also eliminates the necessity to invoke 'grep' + 'awk'.
