<p>The <code>passwd</code> command allows us to change or to assign a password of authentication
|
|||
|
|
of an user currently in the system.<br>
|
|||
|
|
When the user doesn’t have particular privileges, he is only able to change is password,
|
|||
|
|
while the root user has the possibility to change also other users’ passwords.<br>
|
|||
|
|
The command name stands for <i>password</i>.
|
|||
|
|
|

|
|
<h2>Usage</h2>
|
|||
|
|
|
|||
|
|
The default passwd command syntax is:
|
|||
|
|
|
|||
|
|
<pre>
|
|||
|
|
passwd [flags] [user]
|
|||
|
|
</pre>
|
|||
|
|
|
|||
|
|
Where [flags] are the passwd flags, read below for more info, the parameter [user] can only be
|
|||
|
|
specified by the root user. If no user is provided, passwd proceed to set the password of the
|
|||
|
|
user who uses this command. You will first be asked to enter the current user password.
|
|||
|
|
|
|||
|
|
