With links, you can have files exist in many -locations and be accessible by many names. There are two types of links: hard and -soft.</p> - -<p>Hard links are names for a particular file. They can only exist within a single -filesystem and are only removed when the real name is removed from the system. These are -useful in some cases, but many users find the soft link to be more versatile.</p> - -<p>The soft link, also called a symbolic link, can point to a file outside of its -filesystem. It is actually a small file containing the information it needs. You can add -and remove soft links without affecting the actual file. And since a symbolic link is -actually a small file containing its own information, they can even point at a directory. -It's rather common to have <tt class="FILENAME">/var/tmp</tt> actually be a symbolic link -to <tt class="FILENAME">/tmp</tt> for example.</p> - -<p>Links do not have their own set of permissions or ownerships, but instead reflect -those of the file they point to. Slackware uses mostly soft links. Here is a common -example:</p> - -<table border="0" bgcolor="#E0E0E0" width="100%"> -<tr> -<td> -<pre class="SCREEN"> -<samp class="PROMPT">%</samp> <kbd class="USERINPUT">ls -l /bin/sh</kbd> -lrwxrwxrwx 1 root root 4 Apr 6 12:34 /bin/sh -> bash -</pre> -</td> -</tr> -</table> - -<p>The <tt class="COMMAND">sh</tt> shell under Slackware is actually <tt -class="COMMAND">bash</tt>. Removing links is done using <tt class="COMMAND">rm</tt>. The -<tt class="COMMAND">ln</tt> command is used to create links. These commands will be -discussed in more depth in <a href="file-commands.html">Chapter 10</a>.</p> - -<p>It's very important to be careful about symlinks in particular. Once, I was working on -a machine that was consistently failing to back-up to tape each night. Two symlinks had -been made to directories beneath each other. The back-up software kept appending those -same directories to the tape until it was out of space. Normally, a set of checks will -prevent creating a symlink in this situation, but ours was a special case.</p> -</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="filesystem-structure-permissions.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-mounting.html" -accesskey="N">Next</a></td> -</tr> - -<tr> -<td width="33%" align="left" valign="top">Permissions</td> -<td width="34%" align="center" valign="top"><a href="filesystem-structure.html" -accesskey="U">Up</a></td> -<td width="33%" align="right" valign="top">Mounting Devices</td> -</tr> -</table> -</div> -</body> -</html> - |
