The super-user may use these commands to change the properties
of any account. Normal users can only change the properties
of their own account. It may sometimes be necessary to disable
these commands (with <B
CLASS="command"
>chmod</B
>) for normal users,
for example in an environment with many novice users. </P
><P
> Other tasks need to be done by hand. For example, to
change the username, you need to edit
<TT
CLASS="filename"
>/etc/passwd</TT
>
directly (with <B
CLASS="command"
>vipw</B
>, remember). Likewise, to add
or remove the user to more groups, you need to edit
<TT
CLASS="filename"
>/etc/group</TT
> (with <B
CLASS="command"
>vigr</B
>). Such
tasks tend to
be rare, however, and should be done with caution: for
example, if
you change the username, e-mail will no longer reach the
user, unless you also create a mail alias.
