linux下的firefox老崩溃，每次自动退出后，后台总会有好几个firefox进程在运行，原来的做法是
ps ax | grep firefox
然后用 kill -9 [pid] 把查出来的进程一个个杀掉
无聊之中，想到用 python做了个交互式的kill
#!/usr/bin/pythonfrom subprocess import *import osimport sysdef show_ps(ps_name): if ps_name : p1 = Popen(["ps","ax"], stdout=PIPE) p2 = Popen(["grep", ps_name], stdin=p1.stdout, stdout=PIPE) output = p2.communicate()[0] else : p1 = Popen(["ps","ax"], stdout=PIPE) output = p1.communicate()[0] ps_num={} for index,line in enumerate(output.split("\n")): if (line.strip() == ""): continue pid=line.split()[0] print "[%d] %s" % (index, line ) ps_num[index]=pid return ps_numdef main(ps_name): while True: ps_num=show_ps(ps_name) reply = raw_input("enter a number to kill process, enter q quit.") if reply=="": break else : os.system("kill -9 "+ps_num[int(reply)])if __name__ == '__main__': ps_name=None if len(sys.argv) >= 2 : ps_name=sys.argv[1] main(ps_name)
