From: Kajol Jain <kj...@linux.ibm.com> Running shellcheck on lock_contention.sh generates below warning:
In tests/shell/lock_contention.sh line 24: if [ `id -u` != 0 ]; then ^-----^ SC2046 (warning): Quote this to prevent word splitting. In tests/shell/lock_contention.sh line 160: local type=$(head -1 "${result}" | awk '{ print $8 }' | sed -e 's/:.*//') ^--------^ SC3043 (warning): In POSIX sh, 'local' is undefined. ^--^ SC2155 (warning): Declare and assign separately to avoid masking return values. ^-- SC2046 (warning): Quote this to prevent word splitting. Fixed above warnings by: - Adding quotes to avoid word splitting. - Fixing shellcheck warnings for local usage, by prefixing function name to the variable.
