NAME
passwd, chfn, chsh - change a login password, full name or
shell
SYNOPSIS
passwd [user]
chfn [user] fullname
chsh [user] shell
EXAMPLES
passwd # Change current user's password
passwd ast # Change ast's password (super-user
only)
chsh /usr/bin/mail # For those who only read mail
chfn 'Jane Doe' # Current user is Jane Doe
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 file. Chsh changes
your login shell. Do not forget to copy the modified pass-
word file back to the root file system, or the changes will
be lost when the system is rebooted.
