[PATCH 17/22] ver_linux: net-tools, look for numerical input, not field number

From: Alexander Kapshuk
Date: Mon Oct 12 2015 - 14:41:14 EST


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'.
