CDE

Janet Edwards — Tue, 29 Jan 2002 20:36:48 GMT

In a script I need to check if CDE is running. Have any ideas?

If you look for any of the dt* processes, that should be an indication that CDE is running and folks are able to login.

# ps -ef | grep dt

daemon 1885 1864 0 15:23:47 ? 1:34 /usr/bin/X11/X :0 -auth /var/dt/worf:AAAa01864
root 1914 1864 0 15:23:52 ? 0:00 /usr/dt/bin/dtlogin
root 1864 1847 0 15:23:43 ? 0:00 /usr/dt/bin/dtlogin
root 1847 1 0 15:23:42 ? 0:00 /sbin/sh /usr/dt/bin/dtrc
root 2152 1914 0 15:24:24 ? 2:08 dtgreet -display worf:0

Hi Janet,

Look for all 'dt' processes:

# ps -aef | grep dt

Guess I didn't make myself clear, if CDE is enabled, I need to shut it down, whether or not somebody is logged in.

To shut down CDE do a:

# /sbin/init.d/dtlogin.rc stop

Hi,

Check the /etc/rc.log and see whether the CDE was started when the system booted last time. If it was enabled, then you can stop it if you need:

# /sbin/init.d/cdelogin.rc stop
# /sbin/init.d/dtlogin.rc stop

# ps -aef | grep dt - will tell you whether it's running now or not.

fyi :

CDE is started by /sbin/rc3.d/S990/dtlogin.rc which points to /sbin/init.d/dtlogin.rc.

For any system with a local display there will be a :

a) dtlogin (parent) daemon
b) a child dtlogin process running the local CDE session on the local display (for remote connections you'll have additional dtlogin child processes too).

so your script will need to check for dtlogin processes, if true it could run /sbin/init.d/dtlogin.rc stop and check again for dtlogins ..... if they still exist kill them ?
