<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 options:</para>

<variablelist>
<varlistentry>
<term><parameter>--exec-prefix=""</parameter></term>
<listitem><para>This ensures that the Psmisc binaries will install into
<filename class="directory">/bin</filename> instead of <filename
class="directory">/usr/bin</filename>. This is the correct location according to
the FHS, because some of the Psmisc binaries are used by the LFS-Bootscripts
package.</para></listitem>
</varlistentry>
</variablelist>

<para>Compile the package:</para>

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

<para>This package does not come with a test suite.</para>

<para>Install the package:</para>

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

<para>There is no reason for the <command>pstree</command> and
<command>pstree.x11</command> programs to reside in <filename
class="directory">/bin</filename>. Therefore, move them to <filename
class="directory">/usr/bin</filename>:</para>

<screen><userinput>mv -v /bin/pstree* /usr/bin</userinput></screen>

<para>By default, Psmisc's <command>pidof</command> program is not
installed. This usually is not a problem because it is installed later
in the Sysvinit package, which provides a better
<command>pidof</command> program. If Sysvinit will not be used for a
particular system, complete the installation of Psmisc by creating the
following symlink:</para>

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