linux - How to kill program running in background in ubuntu? -

-

i'm working on mini2440 , building custom os using buildroot, testing purpose i'm using os downloaded official website. problem is, i'm using usbpush push os images in mini2440 through usb, popups message when enter below commond

sudo ./usbpush supervivi-128m 0x30008000

unable claim usb interface 1 of device: not claim interface 0: device or resource busy

i don't understand 1 concept that, whenever assign executable permission usbpush, runs automatically in background. it's seen below

ps -ef | grep usb*

silicod+ 2431 2207 0 10:25 pts/10 00:00:00 grep --color=auto usbpush

i tried kill using 

sudo kill -9 2431

but creates new pid , again run itsellf in background. tried googling nothing works me.

=============================================================

well, got solution. don't know problem usbpush tool, downloaded tool , works well. here link tool , may friendly_arm_mini2440_usbpush

cheers....!

lovely ;-)

well guess not running..

ps -ef give details running processes grep usb* - (loose *) find lines containing usb

the way unix/linux grep gets started first , "|" connects output of ps -ef grep's input finding grep command itself

what want ps -ef | grep -v grep | grep usb - work unless "usb" command grepusb or usbgrep or line contains grep..
