<h2>chown - Change file ownership</h2>
|

|
|
|

|
|
<strong>Synopsis</strong>
|
||
|
|
|
||
|
|
<p><strong>chown [-R [ -H | -L | -P ]] [ -h ]</strong> <em>
|
||
|
|
owner</em>[<em>:group</em>] <em>file ...</em></p>
|
||
|
|
|
||
|
|
<p><strong>Description</strong></p>
|
||
|
|
|
||
|
|
<p>You can use <strong>chown</strong> to set the owner of <em>
|
||
|
|
file</em> to the user identifier or profile specified by <em>
|
||
|
|
owner</em>. Optionally, <strong>chown</strong> can also set the
|
||
|
|
group of the <em>file</em> to the group identifier or profile
|
||
|
|
specified by <em>group</em>.</p>
|
||
|
|
|
||
|
|
<p>To change the owner of a file, you must have one of the
|
||
|
|
following authorities:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>The current user has *ALLOBJ special authority.</li>
|
||
|
|
|
||
|
|
<li>The current user is the owner of the file or directory.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>To change the group of a file, you must have one of the
|
||
|
|
following authorities:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>The current user has *ALLOBJ special authority.</li>
|
||
|
|
|
||
|
|
<li>The current user is the owner of <em>file</em> and either one
|
||
|
|
of the following:
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>The primary group of the job is <em>group</em>.</li>
|
||
|
|
|
||
|
|
<li>One of the supplemental groups of the job is <em>
|
||
|
|
group</em>.</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>In addition, the current user must have *USE authority to the
|
||
|
|
new user profile or group profile.</p>
|
||
|
|
|
||
|
|
<p>By default, <strong>chown</strong> follows symbolic links and
|
||
|
|
changes the owner and group of the file pointed to by the symbolic
|
||
|
|
link.</p>
|
||
