I'm probably nitpicking, but if you're using cat to pipe a single file into the sdtin of another program, you most likely don't need the cat in the first place, you can just redirect the file to the process' stdin. Unless, of course, you're actually concatenating multiple files or maybe a file and stdin together.

Disclaimer: I do cat-piping myself quite a bit out of habit, so I'm not trying to look down at the author or anything like that! :)
