I'm confused on why the trap on err spewed the line number but didn't fail the test. While I, maybe others chew on that, thanks for the patch and can you do more :) ? By quoting $monitor_dimms in the -z check ([ ! -z "$monitor_dimms" ]), the script breaks out of the loop correctly and monitors the first region that has DIMMs. I don't know if the test cared if it got the first or second region of nfit_test, but the syntax is definately wrong, and it's error prone in mulitple places in that shell script. '$ shellcheck monitor.sh' shows the instance you found: >> In monitor.sh line 99: >> [ ! -z $monitor_dimms ] && break >> ^-- SC2236: Use -n instead of ! -z. >> ^------------^ SC2086: Double quote to prevent globbing and word splitting. >> >> Did you mean: >> [ ! -z "$monitor_dimms" ] && break >> There are a bunch more instances in need of double quotes. Can you turn this around as a new patch that cleans it all. Note that you might not be able to get rid of all shellcheck complaints in the boilerplate of the script, but should be able to clean up the main body of the script and prevent more problems like you found here. I'll suggest turning this patch into a 2 patches: 1/1: test/monitor.sh address shellcheck bash syntax issues 2/2: test/monitor.sh convert float to integer before increment For 2/2 it does stop the test prematurely. We never run the temperature inject test case of test_filter_dimmevent() because of the inability to increment the float. Please include that impact statement in the commit log. -- Alison > Signed-off-by: Li Zhijian <lizhijian@fujitsu.com> > --- > V1: > V1 has a mistake which overts to integer too late. > Move the conversion forward before the operation > --- > test/monitor.sh | 3 ++- > 1 file changed, 2 insertions(+), 1 deletion(-) > > diff --git a/test/monitor.sh b/test/monitor.sh > index c5beb2c..7809a7c 100755 > --- a/test/monitor.sh > +++ b/test/monitor.sh > @@ -96,7 +96,7 @@ test_filter_region() > while [ $i -lt $count ]; do > monitor_region=$($NDCTL list -R -b $smart_supported_bus | jq -r .[$i].dev) > monitor_dimms=$(get_monitor_dimm "-r $monitor_region") > - [ ! -z $monitor_dimms ] && break > + [ ! -z "$monitor_dimms" ] && break > i=$((i + 1)) > done > start_monitor "-r $monitor_region" > @@ -146,6 +146,7 @@ test_filter_dimmevent() > stop_monitor > > inject_value=$($NDCTL list -H -d $monitor_dimms | jq -r .[]."health"."temperature_threshold") > + inject_value=${inject_value%.*} > inject_value=$((inject_value + 1)) > start_monitor "-d $monitor_dimms -D dimm-media-temperature" > inject_smart "-m $inject_value" > -- > 2.44.0 > >

Shellcheck is catching bad syntax but may not be suggesting the best syntax as an alternative. --Alison snip
