- Hrmf. The rot program is already there, on any Unix box. It is
- called tr:
-
- $ rot () { tr 'a-zA-Z' 'n-za-mN-ZA-M' }
- # for csh users: alias rot tr 'a-zA-Z' 'n-za-mN-ZA-M'
- $ echo 'Render unto Caesar...' | rot
- Eraqre hagb Pnrfne...
- $ echo 'Render unto Caesar...' | rot | rot
- Render unto Caesar...
