That would be the right way to implement it,
_but_ the disadvantage is that this filtering
option is exposed to the users for all these commands.
I'm not sure it's useful enough functionality to expose,
and personally I'd use something like:
children() { find "$1" -maxdepth 1 -mindepth 1; }
or
children() { find "$1" | sed '1d'; }
and then...
children $dir | xargs rm -r

Pádraig.
