Hello, i am a newbie in linux.

Thanks for the help ^^

Hello and Welcome!

To find the status of your processes, try top.

Your other option, if you want a list of every process that's running, is to type

ps aux

into a terminal.

top has the advantage that it gives more info on (for instance) CPU and RAM usage, and it updates itself (every second by default). However, unless you have very few processes running, or a very large screen, top will only show the "busiest" processes. ps aux just prints a long list of everything, so you'll probably have to scroll back up to find a particular one.

A useful trick (which you might well know, but it cant hurt to mention) is to use grep. If for instance you run

ps aux | grep firefox

it will give a list of all the processes listed in the output from ps aux that have "firefox" in the name.

Hope that helps
Giles

Wogh, thanks for the hope...anyway...where could i find the files that contain all this proces,
for example :
if i type ps -aux :
root 2434 0.0 0.4 10220 2508 ? Ss Sep17 0:00 cupsd
root 2453 0.0 0.3 7088 1980 ? Ss Sep17 0:00 /usr/sbin/gdm-b
root 2454 0.0 0.0 1812 420 tty4 Ss+ Sep17 0:00 /sbin/mingetty
root 2455 0.0 0.0 1812 420 tty5 Ss+ Sep17 0:00 /sbin/mingetty
root 2456 0.0 0.0 1812 420 tty2 Ss+ Sep17 0:00 /sbin/mingetty
root 2457 0.0 0.0 1812 420 tty3 Ss+ Sep17 0:00 /sbin/mingetty

there will be result like this....the user and the process id....
where could i find the files that contain all the process that running (contain all process id number)?

ps reads from the /proc directory. If you look in there, you'll see a whole bunch of directories each named with a number. That number is the PID and represents a process. Within those directories is information about that process.

Oh thanks! I look at it.....so basically, if i to know all process that running, i just have to look at the folder with number in /proc, ^^.
At the first, i though that all the process id all saved to some file e.g process.txt or so

Thanks for the help..
