From 1ad45ecbf172bca9d3eeff8750a0eb13731c322e Mon Sep 17 00:00:00 2001
From: Jochen Nitschke <j.nitschke+logerrit@ok.de>
Date: Wed, 11 Jan 2017 11:49:18 +0100
Subject: tdf#105204 shellcheck

addressed issues in order of appearance:
warnings
 - prefer [..] && [..] (SC2166)
 - unused 'awkCMD' (SC2034)
 - typo currentFirstLIne -> currentFirstLine (SC2154)

recommendations
 - use $(..) instead of `..` (SC2006)
 - remove $ on arithmetic variable OPTIND (SC2004)
 - double quote to prevent globbing in $findArgs (SC2086)
