By this point, -you should be able to find files and directories that you need. But there is more to the -filesystem than just the directory structure.</p> - -<p>Linux is a multiuser operating system. Every aspect of the system is multiuser, even -the filesystem. The system stores information like who owns a file and who can read it. -There are other unique parts about the filesystems, such as links and NFS mounts. This -section explains these, as well as the multiuser aspects of the filesystem.</p> - -<div class="SECT1"> -<h1 class="SECT1"><a id="FILESYSTEM-STRUCTURE-OWNERSHIP" -name="FILESYSTEM-STRUCTURE-OWNERSHIP">9.1 Ownership</a></h1> - -<p>The filesystem stores ownership information for each file and directory on the system. -This includes what user and group own a particular file. The easiest way to see this -information is with the <tt class="COMMAND">ls</tt> command:</p> - -<table border="0" bgcolor="#E0E0E0" width="100%"> -<tr> -<td> -<pre class="SCREEN"> -<samp class="PROMPT">%</samp> <kbd class="USERINPUT">ls -l /usr/bin/wc</kbd> --rwxr-xr-x 1 root bin 7368 Jul 30 1999 /usr/bin/wc -</pre> -</td> -</tr> -</table> - -<p>We are interested in the third and fourth columns. These contain the username and -group name that owns this file. We see that the user “<tt -class="USERNAME">root</tt>” and the group “<tt -class="USERNAME">bin</tt>” own this file.</p> - -<p>We can easily change the file owners with the <tt class="COMMAND">chown</tt>(1) (which -means “change owner”) and <tt class="COMMAND">chgrp</tt>(1) (which means -“change group”) commands. To change the file owner to <tt -class="USERNAME">daemon</tt>, we would use <tt class="COMMAND">chown</tt>:</p> - -<table border="0" bgcolor="#E0E0E0" width="100%"> -<tr> -<td> -<pre class="SCREEN"> -<samp class="PROMPT">#</samp> <kbd class="USERINPUT">chown daemon /usr/bin/wc</kbd> -</pre> -</td> -</tr> -</table> - -<p>To change the group owner to “<tt class="USERNAME">root</tt>”, we would -use <tt class="COMMAND">chgrp</tt>:</p> - -<table border="0" bgcolor="#E0E0E0" width="100%"> -<tr> -<td> -<pre class="SCREEN"> -<samp class="PROMPT">#</samp> <kbd class="USERINPUT">chgrp root /usr/bin/wc</kbd> -</pre> -</td> -</tr> -</table> - -<p>We can also use <tt class="COMMAND">chown</tt> to specify the user and group owners -for a file:</p> - -<table border="0" bgcolor="#E0E0E0" width="100%"> -<tr> -<td> -<pre class="SCREEN"> -<samp class="PROMPT">#</samp> <kbd class="USERINPUT">chown daemon:root /usr/bin/wc</kbd> -</pre> -</td> -</tr> -</table> - -<p>In the above example, the user could have used a period instead of a colon. The result -would have been the same; however, the colon is considered better form. Use of the period -is deprecated and may be removed from future versions of <tt class="COMMAND">chown</tt> -to allow usernames with periods in them. These usernames tend to be very popular with -Windows Exchange Servers and are encountered most commonly in email addresses such as: -<var class="LITERAL">mr.jones@example.com</var>. In slackware, administrators are advised -to stay away from such usernames because some scripts still use the period to indicate -the user and group of a file or directory. In our example, <tt class="COMMAND">chmod</tt> -would interpret <var class="LITERAL">mr.jones</var> as user “mr” and group -“jones”.</p> - -<p>File ownership is a very important part of using a Linux system, even if you are the -only user. You sometimes need to fix ownerships on files and device nodes.</p> -</div> -</div> - -<div class="NAVFOOTER"> -<hr align="LEFT" width="100%" /> -<table summary="Footer navigation table" width="100%" border="0" cellpadding="0" -cellspacing="0"> -<tr> -<td width="33%" align="left" valign="top"><a href="shell-vt.html" -accesskey="P">Prev</a></td> -<td width="34%" align="center" valign="top"><a href="index.html" -accesskey="H">Home</a></td> -<td width="33%" align="right" valign="top"><a -href="filesystem-structure-permissions.html" accesskey="N">Next</a></td> -</tr> - -<tr> -<td width="33%" align="left" valign="top">Virtual Terminals</td> -<td width="34%" align="center" valign="top"> </td> -<td width="33%" align="right" valign="top">Permissions</td> -</tr> -</table> -</div> -</body> -</html> - |
