PASSWD(1) — Silicon Graphics
NAME
passwd − change login password
SYNOPSIS
passwd name
DESCRIPTION
This command changes (or installs) a password associated with the login name.
The program prompts for the old password (if any) and then for the new one (twice). The caller must supply these. New passwords should be at least four characters long if they use a sufficiently rich alphabet and at least six characters long if monocase. Only the first eight characters of the password are significant.
Only the owner of the name or the super-user may change a password; the owner must prove he knows the old password. Only the super-user can create a null password.
The password file is not changed if the new password is the same as the old password, or if the password has not "aged" sufficiently; see passwd(4).
EXAMPLE
passwd
will give the response
Changing password for <username>
and will then prompt for your present password and for the new password (twice).
FILES
