The "echo" above was suggested in the previous thread as a way to teach you what would be executed without actually executing it (which would fail because there aren't files and probably fill up the output with error messages). The above loop just prints strings. In order to actually execute the command you should remove the "echo". > > Can someone please have look at what I'm doing and provide a hint/assistance > with my obviously crap command?
