Running shellcheck -S on test_arm_spe.sh throws below warnings: #shellcheck -S warning tests/shell/test_arm_spe.sh In tests/shell/test_arm_spe.sh line 30: trap cleanup_files exit term int ^--^ SC3049 (warning): In POSIX sh, using lower/mixed case for signal names is undefined. ^--^ SC3049 (warning): In POSIX sh, using lower/mixed case for signal names is undefined. ^-^ SC3049 (warning): In POSIX sh, using lower/mixed case for signal names is undefined. Fixed this issue by using uppercase for "EXIT", "TERM" and "INIT" signals to avoid using lower/mixed case for signal names as input.
