6.26.1. Installation of Psmisc
|
|
</h2>
|
|
<p>
|
|
Prepare Psmisc for compilation:
|
|
</p>
|
|
<pre class="userinput">
|
|
<kbd class="command">./configure --prefix=/usr</kbd>
|
|
</pre>
|
|
<p>
|
|
Compile the package:
|
|
</p>
|
|
<pre class="userinput">
|
|
<kbd class="command">make</kbd>
|
|
</pre>
|
|
<p>
|
|
This package does not come with a test suite.
|
|
</p>
|
|
<p>
|
|
Install the package:
|
|
</p>
|
|
<pre class="userinput">
|
|
<kbd class="command">make install</kbd>
|
|
</pre>
|
|
<p>
|
|
Finally, move the <span class=
|
|
"command"><strong>killall</strong></span> and <span class=
|
|
"command"><strong>fuser</strong></span> programs to the location
|
|
specified by the FHS:
|
|
</p>
|
|
<pre class="userinput">
|
|
<kbd class="command">mv -v /usr/bin/fuser /bin
|

mv -v /usr/bin/killall /bin</kbd>
