Dear Users,

I use RHEL6. I was configuring unpartitioned space for LVM. After creating a new partition, the mouse selection was on /boot partition and I changed the type to 0x8e by mistake.A spinning circle appeared indicating the process of changing the type from default linux 0x85 to 0x8e. I restarted and everything was okay. But the question is "Is it possible to stop such processes initiated using GUI utility from command line to prevent any damage to the configuration of the system?".

Thanks.

First, you must know the process ID or its name. To see the list of processes, you can execute:

Once you know which process is it you want to kill, you execute:

PID is the process ID number returned by ps. You can also use the command killall with the real process name. So for example, if you want to stop firefox from the CLI, you can either execute:

or:

firefox-PID is the real ID number returned by ps.

There is also pkill (I haven't used this one, but you can check the man page for it, if you're interested to know about it: man pkill).

(Of course, you must be careful about which processes you kill, since there are critical process that, if killed, may cause data loss or an unstable system).

If you are too lazt to find the PID (like me) I recommend 'skill'.
Hope this helps.

xkill

Did you notice that the previous poster described the kill command in some detail? Your posts sometimes appear to be simply promoting your website.

Thanks.that worked.
