Subject: Remove awk dependency
X-Git-Tag: accepted/tizen/unified/20170824.050910~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fa7e37e2b2a3ecf962a08d3cca5353af861bc92d;p=platform%2Fcore%2Fsystem%2Finitrd-fota.git

Remove awk dependency

To be optimized, awk package got out of initrd-recovery.
So, make the same code using coreutil commands instead of awk.
