chkconfig - configuration state checker
chkconfig [ -s ]
chkconfig [ -f ] flag [ on | off ]
chkconfig with no arguments or with the -s option prints the state (on or
off) of every configuration flag found in the directory /var/config. The
flags normally are shown sorted by name; with the -s option they are
shown sorted by state.
A flag is considered on if its file contains the string ``on'' and off
If flag is specified as the sole argument, chkconfig exits with status 0
if flag is on and with status 1 if flag is off or nonexistent. The exit
status can be used by shell scripts to test the state of a flag. Here is
an example using sh(1) syntax:
if /sbin/chkconfig verbose; then
echo "Verbose is on"
echo "Verbose is off"
The optional third argument allows the specified flag to be set. The
flag file must exist in order to change its state. Use the -f
(``force'') option to create the file if necessary.
These flags are used for determining the configuration status of the
various available subsystems and daemons during system startup and during
A daemon or subsystem is enabled if its configuration flag in the
/var/config directory is in the on state. If the flag file is missing,
the flag is considered off. The following is a list of available flags
and the associated action if the flag is on. Depending upon your
configuration, they may not all be available on your system.

desktop If off, fewer of the IRIX Interactive Desktop(TM) user
interface features are enabled, and typically a different
toolchest menu is used. It is identical to creating the
file $HOME/.disableDesktop except that it applies to all
accounts. The specific effect is that the desktop
version of Xsession (/usr/lib/X11/xdm/Xsession.dt) is not
run upon login, and therefore programs started from that
file are not run or are run with different options.

lockd Start the NFS lock and status daemons.
mediad Start the removable media daemon.

pmie(1) and pmie_check(1) for more details.
privileges Enable privileges to be used on the system. See
runpriv(1M) and privilege(4) for more details.

enabled. See quotas(4) for more details.

rsvpd Start the RSVP daemon. See rsvpd(1M) for more details.
rtnetd Initialize preemptable networking for real-time use.
rwhod Start the 4.3BSD rwho daemon.
sar Start the system activity reporter.
savecore Enable the saving of kernel crash images. Some
information is saved in /var/adm/crash even if saving is

timed Start the 4.3BSD time synchronization daemon.
timeslave Start the Silicon Graphics time synchronization daemon.
verbose Print the names of daemons as they are started.

visuallogin Enable the visual login screen.
windowsystem Start the X window system. If windowsystem is off, it is
necessary to modify the inittab(4) file to enable
