no need for a for loop when cat takes multiple arguments
There are 4 alternatives - vote for the best!
The better alternative to #9756.
I don't think I'd ever use the original command, but this one was so bad I had to post this. Sorry.
1. $(ls) is dumb, and will give errors if you have an alias like "ls -Fs"
2. clear is better and more portable than reset state.
3. if you're interested in differences, then use diff, not cat.
Original submitted version would break if any filenames had whitespaces in them. The command is a Bad Idea anyhow, because you will end up `cat`ing a binary or something else specacularly bad.
If you can do better, submit your command here.
