Thanks for the reply! I think I might have been a little unclear in trying to be extra-brief.
What I am really curious about is whether there is a simpler way to call the unknown-named executable. I'll try to one-liner it:
If I have a directory with a single executable file, but I don't know the name of it, is there a better way than the for loop I listed in the original post?
It's definitely not a big deal, especially for my specific example, but I just get the feeling maybe there's something I can learn here.
