When we run Jmeter from command line we do not get a report like we do using "Summary Report" listener. However, command line utility can save the output in csv file and we can generate "Summary Report" like output in a text file using shell script.
Run below command from command to execute your test plan and generate output in csv.
jmeter.sh -n -t -l
ex-
./jmeter.sh -n -t /home/abhishek/TestSampler.jmx -l /home/abhishek/SampleOutput.csv
Run the script with output file as its argument
./SummaryReport.sh SampleOutput.csv
