kill any process Forcibly in Unix March 18, 2010

Often it happens that some programs hangs and it doesnot close by clicking the “X ” button.In that case we can use “$kill ” command to kill the process.”$Kill” has several options attached with it. To kill something forcibly we use “-9″ option. I show u some example.
——————
step1:->
$ps -a
-> this will list all process (but not that which runs in the background)
$ps -e
->this will list all process , evem those that runs in the background

—————————————
step2->
Now that we have listed the process by above two methods, chose the “pid” of that process which u want to kill
$kill “pidnumber”
->where pidnumber is the one u noted from above which u want to stop.
**this may not kill some process. So for this use -9 option
$kill -9 “pidnumber”
-> now ur required process will be closed
———————————–
Actually sometimes while using TopCoder Arena, the applet didnot closes or it Hangs, To stop it either i has to restart the system or i had to log off and then log in. Now through theses commnads with -9 option i can close it.
sample:->

TopCoder Arena launching in fedora(linux) February 12, 2010

Today i launched Topcoder arena in feodra. To do this just save the tocoderapplet file and then open it with firefox and then enter option …/../jawas which is located in java folder or jre folder of java……………

Now i will start doing problems over here also. One important thing about topcoder is that it doesnot use ” main ” function .However method has to be defined public.

TopCoder!!!!!!!!!!!!!
