Run Bash script with Robot Framework

I am trying to run a bash script with robot framework test case. The bash script includes two for loops and after investigation the script runs only the first loop and stuck on the second loop of bash script. Have you ever faced the same problem?

Thank you.

Could you clarify you problem? Using the command line, you can run multiple test suites by reffering to the suite files (.robot) or to folders containing .robot files (suite of suites). Why are you running a loop?
