From: Spoorthy S <spoor...@in.ibm.com>
Running shellcheck -S on stat+shadow_stat.sh testcase, generates
SC2046 and SC2034 warnings,
$ shellcheck -S warning tests/shell/stat+shadow_stat.sh
res=`printf "%.2f" $(echo "scale=6; $num / $cyc" | bc -q)`
: Quote this to prevent word splitting
To address the POSIX shell warnings used quotes in the printf
expressions, to prevent word splitting.
