files with <tt class="COMMAND">ln</tt></a></h1>
|
||
|
|
|
||
|
|
<p><tt class="COMMAND">ln</tt>(1) is used to create links between files. These links can
|
||
|
|
be either hard links or soft (symbolic) links. The differences between the two kinds of
|
||
|
|
links were discussed in <a href="filesystem-structure-links.html">Section 9.3</a>. If you
|
||
|
|
wanted to make a symbolic link to the directory <tt class="FILENAME">/var/media/mp3</tt>
|
||
|
|
and place the link in your home directory, you would do this:</p>
|
||
|
|
|
||
|
|
<table border="0" bgcolor="#E0E0E0" width="100%">
|
||
|
|
<tr>
|
||
|
|
<td>
|
||
|
|
<pre class="SCREEN">
|
||
|
|
<samp class="PROMPT">%</samp> <kbd class="USERINPUT">ln -s /var/media/mp3 ~/mp3</kbd>
|
||
|
|
</pre>
|
||
|
|
</td>
|
||
|
|
</tr>
|
||
|
|
</table>
|
||
|
|
|
||
|
|
<p>The <var class="OPTION">-s</var> option tells <tt class="COMMAND">ln</tt> to make a
|
||
|
|
symbolic link. The next option is the target of the link, and the final option is what to
|
||
|
|
call the link. In this case, it will just make a file called <tt
|
||
|
|
class="FILENAME">mp3</tt> in your home directory that points to <tt
|
||
|
|
class="FILENAME">/var/media/mp3</tt>. You can call the link itself whatever you want by
|
||
|
|
just changing the last option.</p>
|
||
|
|
|
||
|
|
<p>Making a hard link is just as simple. All you have to do is leave off the <var
|
||
|
|
class="OPTION">-s</var> option. Hard links may not normally refer to directories or span
|
||
|
|
file systems, however. To create a hard link <tt class="FILENAME">/usr/bin/email</tt> to
|
||
|
|
<tt class="FILENAME">/usr/bin/mutt</tt>, simply type the following:</p>
|
||
|
|
|
||
|
|
<table border="0" bgcolor="#E0E0E0" width="100%">
|
||
|
