I want to kill all process for a particular user , I know I can use ps -ef to find the pid , but I found that it only find the pid , if I want to kill all process of a particular user by one time , is there any kill command can do that ? thx

use this command

ps -ef | awk '{print $1" "$2}' | grep | awk '{print $NF}' | xargs kill

It will kill a users all processes at a glance.

be careful. Before running this please check first if the processes are significant.

'ps -u' is your friend.

ps -u | awk '{system("kill -TERM " $1)}'

You can use
pkill -u username
or
pkill -u username -s signalname

thx reply ,

I have pkill in my box, I use pkill command before , it is good to kill the deamon , for example if I want to kill all httpd process , it can kill all httpd process by one time ( pkill httpd ), but is it suitable to use for killing the user process ? because the user process involves the init process ( the ppid is 1 ) , if use pkill , I am afraid it will kill other process that generate from other user . Thx for advise.

"pkill -u username" will only kill processes that have effective user id "username". I don't understand your concern about parent processes.
