Linux下强制杀死进程的方法详解

(编辑：jimmy 日期: 2024/9/21 浏览：2)
常规篇：
首先，用ps查看进程，方法如下：
$ ps -ef
……
smx 1822 1 0 11:38 "htmlcode">

……

smx 1822 0.1 0.8 58484 18152 "htmlcode">

smx 1827 1 4 11:38 "-9" 即发送的信号是9，pkill与kill在这点的差别是：pkill无须 “ｓ”，终止信号等级直接跟在 “-“ 后面。之前我一直以为是 "-s 9"，结果每次运行都无法终止进程。
改进10——killall：
killall和pkill是相似的,不过如果给出的进程名不完整，killall会报错。pkill或者pgrep只要给出进程名的一部分就可以终止进程。
$killall -9 firefox
