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.
