I'm not sure it's that complicated. Maybe I'm overlooking something
obvious, but something like "sort -t: -k3n" seems like it ought to
suffice for sorting /etc/passwd and /etc/group on numeric id.
I didn't understand Patrick's comment about "id not present in each
file" though, maybe that's the key to the extra complexity.
