I think it impacted all version of BASH (tested on bash 4.1, 4.2, 5.0, 5.1) > >> >> Signed-off-by: Li Zhijian <[email protected]> >> --- >> test/cxl-region-sysfs.sh | 8 ++++---- >> 1 file changed, 4 insertions(+), 4 deletions(-) >> >> diff --git a/test/cxl-region-sysfs.sh b/test/cxl-region-sysfs.sh >> index ded7aa1..89f21a3 100644 >> --- a/test/cxl-region-sysfs.sh >> +++ b/test/cxl-region-sysfs.sh >> @@ -108,8 +108,8 @@ do >> >> sz=$(cat /sys/bus/cxl/devices/$i/size) >> res=$(cat /sys/bus/cxl/devices/$i/start) >> - [ $sz -ne $region_size ] && err "$LINENO: decoder: $i sz: $sz >> region_size: $region_size" >> - [ $res -ne $region_base ] && err "$LINENO: decoder: $i base: $res >> region_base: $region_base" >> + [ "$sz" != "$region_size" ] && err "$LINENO: decoder: $i sz: $sz >> region_size: $region_size" >> + [ "$res" != "$region_base" ] && err "$LINENO: decoder: $i base: $res >> region_base: $region_base" > > maybe use ((sz != region_size)) to make it explicit that this is an > arithmetic comparison? I would defer to Vishal's preference here. Per bash man page, we can also use [[ ]] instead of [ ], so that we are able to get rid of patch1 arg1 OP arg2 OP is one of -eq, -ne, -lt, -le, -gt, or -ge. These arithmetic binary operators return true if arg1 is equal to, not equal to, less than, less than or equal to, greater than, or greater than or equal to arg2, respectively. Arg1 and arg2 may be positive or negative integers. When used with the [[ command, Arg1 and Arg2 are evaluated as arithmetic expressions (see ARITHMETIC EVALUATION above).
