如何通过名称而不是PID杀死进程?

问题描述

有时，当我尝试启动Firefox时，显示"Firefox进程已在运行".所以我必须这样做:

Sometimes when I try to start Firefox it says "a Firefox process is already running". So I have to do this:

jeremy@jeremy-desktop:~$ ps aux | grep firefox
jeremy    7451 25.0 27.4 170536 65680 ?        Sl   22:39   1:18 /usr/lib/firefox-3.0.1/firefox
jeremy    7578  0.0  0.3   3004   768 pts/0    S+   22:44   0:00 grep firefox
jeremy@jeremy-desktop:~$ kill 7451

我想要的是一个可以为我做所有事情的命令.它会在进程列表中使用一个输入字符串和grep(或其他任何字符串)，并杀死输出中的所有进程:

What I'd like is a command that would do all that for me. It would take an input string and grep for it (or whatever) in the list of processes, and would kill all the processes in the output:

jeremy@jeremy-desktop:~$ killbyname firefox

我尝试在PHP中执行此操作，但exec('ps aux')似乎仅显示PHP脚本本身中已使用exec()执行的进程(因此，它显示的唯一进程是其自身.)

I tried doing it in PHP but exec('ps aux') seems to only show processes that have been executed with exec() in the PHP script itself (so the only process it shows is itself.)

推荐答案

pkill firefox
