passwd
PURPOSE
Changes your login password.
SYNOPSIS
passwd name
DESCRIPTION
The passwd command establishes or changes the password
associated with your login user name. When you enter
this command, you get a prompt for the old password if
one exists. Then you get two successive prompts for the
new password. You must enter the same password twice for
it to take effect.
Passwords can be from four to eight characters. Only the
owner of the password or the superuser can change it. To
change a password, the owner must know the old password.
Only a user operating with superuser authority can create
a null password (by removing the password entry from the
/etc/passwd file).
The system password file does not change when a new pass-
word is the same as the old one, nor does it change if
the password has not aged sufficiently.
Note: The /etc/passwd and /etc/opasswd files must be on
the same node.
FILES
/etc/passwd Password file; contains user ids.
/etc/opasswd Previous version of the password file.
