That still doesn't explain why it is there.
After the options have been parsed, $1 can never contain -s, so why do you test for it?
The variable $searchstring can never have any value (unless is has been exported in the calling environment). And why do you test for a file with that name, even if it could have a value?

About the five 'UUOCs' those are only for test purposes........
They are not needed for anything, testing or otherwise.

The command that I would run from my terminal would be
kevin@ubuntu:~/Documents/Practice$: ./test
If you are not calling it with any arguments, why do you want them parsed?????
