Subject: perf test: Replace 'grep | wc -l' with 'grep -c'
X-Git-Tag: v6.6.17~4887^2~413
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5b420cf003da4da34955dfd95c5334bec0815114;p=platform%2Fkernel%2Flinux-rpi.git

perf test: Replace 'grep | wc -l' with 'grep -c'

To count the number of results from grep, use the '-c' parameter
instead of piping it to 'wc'.
