I'm creating a junk script which utilizes either -l or -p to list files or remove files, respectively, in the junk directory. When I run this code, inputting '-p' is unrecognized through the whole if/else block and falls to the last else (echo do nothing). In addition, I switched tests and tested for '-p' first, seeing if I could uncover hints, and inputting '-l' still made it catch on that first test even though it was testing for '-p'! (with input of -p still falling through.)
So confused. I've tried different quoting schemes, but maybe not the right one.
