PASSWD(1) General Commands Manual PASSWD(1)
NAME
passwd, chfn, chsh - change a login password, full name or shell
SYNOPSIS
passwd [user]
chfn [user] fullname
chfn [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 password file back to the root file system, or the changes will be lost when the system is rebooted.
