Subject: [Linux-users] help wanted with sed usage
Hi all sed gurus (& wannabes like me),
Wanting to `sed` beyond my present understanding;
echo abcdefghijklmnopqrstuvwxyz | sed 'keep first 5
chars, then append a Z to every fourth char thereafter, and keep the
leftovers too'
ie
abcdefghiZjklmZnopqZrstuZvwxyZz
I think sed would be capable of this - but haven't
proven it yet.
