How to kill a process or application

vitalstrike82 · 02-16-2008, 10:05 AM

Hi, i have encounter a problem once when i close the firefox and click on the icon to start again, it says the firefox did not close properly and ask me to kill the process.

This how i start
ps -ef

Then this is the result:
UID PID PPID C STIME TTY TIME CMD
1000 17264 17259 1 Feb16 ? 00:01:50 /usr/lib/firefox/firefox-bin

17264 is the PID and 17259 is the PPID. How do i kill the firefox? is it kill 17264? I type and it responds an error?

How do i go to kill the process?

Please guide..

Be root (or use sudo in front of the commands given.
Do:
Code:
```
# ps axu | grep firefox
```
in order to find the process (it will have a different PID every time it happens; for other applications, replace "firefox".
Do:
Code:
```
# kill 17264
```
or (if it doesn't work):
Code:
```
# kill -9 17264
```
(replace "17264" with the actual PID).

That should do it (btw. "ps axu" does more or less the same as "ps -ef" - use whatever you like better).
