- DESCRIPTION
- Passwd is used to change your password. It prompts for the old and new
- passwords. It asks for the new password twice, to reduce the effect of a
- typing error. Chfn changes the full name (GECOS field) in the password

- password file back to the root file system, or the changes will be lost
- when the system is rebooted.
