The other day on the Internet I found a shell tip that showed how to use
cp or mv with only a single argument. I tried it in the default pdksh in
OBSD and it worked. I thought to myself, I can't believe I have been
using the shell for over 8 years and didn't know that. Now I can't
remember how to do it or where I found the tip. Does anybody know what
I'm talking about? (I'm too lazy to look through source for this)
This obviously isn't correct, but it went something like this:
$ ls
test
$ cp {test,.bak}
$ ls
test test.bak
This is not actually invoking cp with only one argument. See here:
$ set -x
$ touch test
+ touch test
$ cp test{,.bak}
+ cp test test.bak
With "set -x", the shell will tell us exactly what gets executed.
