Or, for even less typing:
$ mkdir -p FOO/foo-{1,2,3}
Understand how this works, however, so you won't need to look it up
again, but can apply it yourself in whatever variation is needed. It's
called brace expansion. Here's the first hit that comes up in Google,
which describes it fairly well:

This page is about the bash shell, but brace expansion works the same
way in tcsh. It is NOT supported in tne Bourne shell.
