Dear Holger,
I dont think I managed to get this to work. Actually
I am not sure if the pipes are working, because I am
getting no output for
$ ps |grep Xwin
However for
$ ps
PID PPID PGID WINPID TTY UID
STIME COMMAND
23492 1 23492 23492 con 500
11:06:42 /usr/X11R6/bin/XWin
25152 1 25152 25152 con 500
13:14:28 /usr/bin/xterm
I 25188 25152 25188 25208 0 500
13:14:28 /usr/bin/bash
26456 1 26456 26456 con 500
13:18:41 /usr/bin/xterm
I 26492 26456 26492 26512 1 500
13:18:41 /usr/bin/bash
26128 1 26128 26128 con 500
13:28:20 /usr/bin/bash
23048 26128 23048 20344 con 500
13:28:23 /usr/bin/ps
So this seems OK so I am wondering why the former
command did not work. Could this be a problem with the
Pipe?? I have no experience with this.
Thanks a lot for your help,
O.O.
