<title>Installation of Psmisc</title>

<para>Prepare Psmisc for compilation:</para>

<screen><userinput>./configure --prefix=/usr --exec-prefix=/</userinput></screen>

<para>The meaning of the configure option:</para>

<itemizedlist>
<listitem><para><userinput>--exec-prefix=/</userinput>: This causes the
binaries to be installed in <filename>/bin</filename> and not in
<filename>/usr/bin</filename>. As the Psmisc programs are often used in
bootscripts, they should be available also when the <filename>/usr</filename>
filesystem isn't mounted.</para></listitem>
</itemizedlist>

<para>Compile the package:</para>

<screen><userinput>make</userinput></screen>

<para>And install it:</para>

<screen><userinput>make install</userinput></screen>

<para>There is no reason for the <filename>pstree</filename> and
<filename>pstree.x11</filename> programs to reside in
<filename class="directory">/bin</filename>. We therefore move them to
<filename class="directory">/usr/bin</filename>. Also, there is no need
for <filename>pstree.x11</filename> to exist as a separate program. We
therefore make it a symbolic link to <filename>pstree</filename>:</para>

<screen><userinput>mv /bin/pstree* /usr/bin
ln -sf pstree /usr/bin/pstree.x11</userinput></screen>

<para>By default Psmisc's <userinput>pidof</userinput> program isn't installed.
Generally, this isn't a problem because we later install the Sysvinit package,
which provides a better <userinput>pidof</userinput> program. But if you're not
going to use Sysvinit, you should complete the installation of Psmisc by
creating the following symlink:</para>

<screen><userinput>ln -s killall /bin/pidof</userinput></screen>
