Module 1 Assessment issue

I have run my code in terminal it is running fine, but when i submit it then test case shows error (error : returncode> 0) .

I get the output while I run it on the workspace.
Please help me out.

Your code should run irrespective of current directory in the terminal. In whichever directory a terminal is present, your code should work.

Write some more commands on print_home_directory.sh.

please check my code sir.
My list_files.sh gives me error of returncode 0.
Rest all have passed the test cases.

I am stuck on module 1 for too long.
I do not understand why list_files.sh is not passing the test case, there seems nothing wrong with my code.
All the other files have passed the test cases.

Please help me out.
