This Red Hat tool is used to manage automatic startup of services on boot. A service needs a valid startup script in <code>/etc/init.d</code> to be eligible. The init startup must contain two commented lines somewhere at the top. For example:
<pre>
# chkconfig: 2345 20 80
# description: Saves and restores system entropy pool for \
# higher quality random number generation.
</pre>

2345 represents the runlevels in which the service should be up. 20 is startup priority and 80 is shutdown priority.

To see all entries:
<pre>
chkconfig --list
</pre>

To see an entry for a particular service:
<pre>
chkconfig --list <service>
</pre>

To add a service that has a valid startup script in /etc/init.d:
<pre>
chkconfig --add <service>
</pre>

To delete a service from the chkconfig system:
<pre>
chkconfig --del <service>
</pre>

To turn a service on or off:
<pre>
chkconfig <service> on|off
</pre>
