what is the process number of a "running application" ?

[Angelo Moreschini]

Hi,

I would like to know the process number of an application that actually is
running (Netbeans in my case), with the purpose to kill it (when is froze).

But am am not able to know this process number..

- In the window of gnome-system-monitor the name "netbeans" isn't.
- The command line : "ps aux | grep netbeans",  give me a full page of
references..

Could I know a simple way to have this information ?

Thank you
Regards

Angelo

ps auxw | grep -i netbeans

or use top  (top has a Kill command)

It's in java-*-openjdk-devel, as shown by `yum provides '*/jps'`.

It's a Java progra, so use "jps":

 $ jps -l
32490 org.netbeans.Main
32751 sun.tools.jps.Jps

CAVEATS
This command does not provide any warranty that the application whose connection to the X
server is closed will abort nicely,
or even abort at all. All this command does is to close the connection to the X server.
Many existing applications do indeed abort when their connection to the X server is
closed, but some can choose to continue.

There's no reason to use sudo for xkill.  Root can't do anything with 
xkill that you, as the X session owner, cannot do.

xkill doesn't kill an application, it causes the X server to disconnect 
the client application.  Usually that will cause the application to 
exit, but if it's well and truly stuck, it may continue consuming memory 
and CPU resources in the background, in which case you'll still need to 
track it down and kill it.

thank you,

I found a very simple as well very elegant way to kill an application, if
it has a graphic interface on the screen:

the
result of this command is a a "particular shape of the cursor" that can
be used to terminate a program, simply clicking on his window with this
cursor.. [?].

It works really very good..

The name is probably "java" then.  Right-click on any java processes and 
select "Properties."  The resulting window will contain the "Command 
Line" that invoked the process, and that should tell you whether you're 
looking at netbeans or some other java process.  When you've found it, 
you can right-click to end or kill the process.  You don't need the PID 
to do so from the gnome-system-monitor.

Amongst the other suggestions, there's the killall command.  I've often
used it when mplayer has choked on some media file and won't play it,
nor quit, it just jammed (e.g. killall mplayer), occasionally I'll have
to issue the command more than once, or be more forcefull in putting an
end to a seriously jammed played (e.g. killall -9 mplayer).
