passwd(1) General Commands Manual passwd(1)
Name
passwd - create or change password
Syntax
passwd [-aefs] [name]
Description
The command lets you or the superuser change your password. When you enter the command, the program prompts you for the old password and
then for the new password. Next, the program asks you for the new password again, to verify that you have typed it correctly. Note that
the passwords are not displayed on the screen.
Your new password must meet the length requirements specified by the superuser. To review these requirements, refer to the file. (This is
a read-only file.)
If your system is running with increased security, you may have to choose a password from a list of randomly generated passwords, or you
may need authorization to change your password. At higher security levels, you may be prohibited from changing your password until its
minimum lifetime has expired, as specified in the Authorization Database.
If you are running the BIND/Hesiod service, your password will be updated automatically on the server.
Options
-a Supply a list of randomly generated passwords. (See the Examples section.)
-e Use an extended protocol when communicating with a prompter program. As a result, the standard input and output (used by is sent to
this program.
-f Change the finger information, not the password. The finger program provides information about current ULTRIX users, such as login and
terminal name, idle time and office location.
-s Change the login shell of the password file, not the password entry.
Restrictions
If you use a hardcopy terminal, you must destroy all print outs of valid passwords.
Examples
The following example illustrates the -a option, which displays a list of randomly generated passwords and their suggested pronunciation
with hyphens. The hyphens delineate the syllables of the passwords:
passwd -a abcd
Changing password for abcd
Here are some suggested passwords:
ryegd ryeg-di
aswurku a-swurk-u
ryedok ryed-ok
teleccs tel-ec-cos
wahislas wa-hi-slas
Enter new password:
