Please post exactly your terminal session where you tried and got errors. Select the text and cut/paste that into a

Because it could be things like:
- Incorrect execute permissions
- Incorrect arguments being given to the script
- Needing to run using sudo
- Unable to run because you don't have a certain system command
- Or other things
