Ss?? 11:38?? 0:00 bashsmx?????? 1880? 0.0? 0.6? 41536 12620 ???????? S??? 11:38?? 0:00 update-notifier……smx????? 11953? 0.0? 0.0?? 2716? 1064 pts/0??? R+?? 21:42?? 0:00 ps -aux此时如果我想杀了火狐的进程就在终端输入：$ kill -s 9 1827其中-s 9 制定了传递给进程的信号是９，即强制、尽快终止进程。各个终止信号及其作用见附录。1827则是上面ps查到的火狐的PID。简单吧，但有个问题，进程少了则无所谓，进程多了，就会觉得痛苦了，无论是ps -ef 还是ps -aux，每次都要在一大串进程信息里面查找到要杀的进程，看的眼都花了。进阶篇：改进１：把ps的查询结果通过管道给grep查找包含特定字符串的进程。管道符“|”用来隔开两个命令，管道符左边命令的输出会作为管道符右边命令的输入。$ ps -ef | grep firefoxsmx?????? 1827???? 1? 4 11:38 ???????? 00:27:33 /usr/lib/firefox-3.6.18/firefox-binsmx????? 12029? 1824? 0 21:54 pts/0??? 00:00:00 grep --color=auto firefox这次就清爽了。然后就是$kill -s 9 1827还是嫌打字多？改进２——使用pgrep：一看到pgrep首先会想到什么？没错，grep！pgrep的p表明了这个命令是专门用于进程查询的grep。$ pgrep firefox1827看到了什么？没错火狐的PID，接下来又要打字了：$kill -s 9 1827改进３
