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. SEE ALSO login(1), su(1), crypt(3), getpwent(3).
