Not all shells define a variable UID. This is a bash and zsh feature only. In other shells, the UID variable is not defined, so here test command expands to [ != 0 ] which is a syntax error. Without this patch: root@HGH1000007090:/opt/work/linux/tools/testing/selftests/zram# sh zram.sh zram.sh: 8: [: !=: unexpected operator zram.sh : No zram.ko module or /dev/zram0 device file not found zram.sh : CONFIG_ZRAM is not set With this patch: root@HGH1000007090:/opt/work/linux/tools/testing/selftests/zram# sh ./zram.sh zram.sh : No zram.ko module or /dev/zram0 device file not found zram.sh : CONFIG_ZRAM is not set Signed-off-by: Zhang Zhen <zhenzhang.zhang@huawei.com> Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>
