I often need to kill a process during programming. The way I do it now is: [~]$ ps aux | grep 'python csp_build.py' user 5124 1.0 0.3 214588 13852 pts/4 Sl+ 11:19 0:00 python csp_build.py user 5373 0.0 0.0 8096 960 pts/6 S+ 11:20 0:00 grep python csp_build.py [~]$ kill 5124 How can I extract the process id automatically and kill it in the same line? Like this: [~]$ ps aux | grep 'python csp_build.
