dynamic menu

[ibzrg470]

something I wrote to pass the time at work....

You can input any command you want at the first case option, for now it just runs and ls -l against the file you choose.

I'm going to use it for running snes roms.

The script handles spaces with no problem, but it gets hung up on files with numbers in it because grep finds the first instance of the expression.

Enjoy!
