NAME

passwd − change login password

SYNOPSIS

passwd [ name ]

DESCRIPTION

This command changes (or installs) a password associated with the user name (your own name by default). 

The program prompts for the old password and then for the new one.  The caller must supply both.  The new password must be typed twice, to forestall mistakes. 

It is suggested that new passwords be at least four characters long if they use a sufficiently rich alphabet and at least six characters long if monocase. 

Only the owner of the name or the super-user may change a password; the owner must prove he knows the old password. 

EXAMPLE

passwd

responds "Changing password for <username>, then asks for your password (once) and for the new password (twice). 

FILES

/etc/passwd
