Subject: [PATCH 0/2] Script style improvements in lib/coresight.sh
Date: Wed, 1 Feb 2023 22:49:43 +0100 [thread overview]
Message-ID: <20230201214945.127474-1-didi.debian@cknow.org> (raw)
These 2 patches improve the efficiency and quality of the
lib/coresight.sh script.
The first one uses grep's `-c` parameter to count the results instead of
piping it to `wc -l`.
The second one replaces the use of backticks (`...`) with $(...) as the
former has several potential issues while the latter does not.
Diederik de Haas (2):
perf test: Replace 'grep | wc -l' with 'grep -c'
perf test: Replace legacy `...` with $(...)
