Linux下使用命令结束进程

来源：互联网发布：日军退子弹知乎编辑：程序博客网时间：2024/06/01 17:02

有时候某个软件卡死，想直接Kill掉。

1.ps -ef 或者 ps -aux 查看当前所有的进程：

xxxx:project/ $ ps -ef                                                                                                   [0:32:26]UID        PID  PPID  C STIME TTY          TIME CMDroot         1     0  0 Sep13 ?        00:00:00 /sbin/initroot         2     0  0 Sep13 ?        00:00:00 [kthreadd]root         3     2  0 Sep13 ?        00:00:00 [ksoftirqd/0]root         5     2  0 Sep13 ?        00:00:00 [kworker/0:0H]root         7     2  0 Sep13 ?        00:00:02 [rcu_sched]......

2. kill -s 9 process_id (-s means signal )

USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMANDroot         1  0.0  0.0  34032  4592 ?        Ss   Sep13   0:00 /sbin/init

PID is the processID

3. ps -ef或者ps -aux 两者列出来的进程都比较多，我们可以过滤。然后找到pid直接kill掉该进程。

xxxx:project/ $ ps -ef | grep firefox                                                                                    [0:39:56]xxxx   3027  1753  1 Sep13 ?        00:02:09 /usr/lib/firefox/firefoxxxxx  12604  9060  0 00:40 pts/1    00:00:00 grep --color=auto --exclude-dir=.bzr --exclude-dir=.cvs --exclude-dir=.git --exclude-dir=.hg --exclude-dir=.svn firefox

4. pgrep firefox pgrep 是专门用于进程查询的

xxxx:project/ $ pgrep firefox                                                                                            [0:41:26]3027

如果这里能直接查出pid则，我们后面使用管道符号，直接干掉该进程

1)pgrep firefox | xargs kill -s 9

或者

2)kill -s 9 'grep firefox'

或者

3)pkill -9 firefox

5. 使用 pidof 查询

xxxx:project/ $ pidof firefox                                                                                            [0:43:01]3027

6.ps -ef|grep firefox|grep -v grep|cut -c 9-15|xargs kill -s 9

xxxx:project/ $ ps -ef|grep firefox|grep -v grep|cut -c 9-15|xargs kill -s 9

各种信号的含义：常见的有signal 11 / 9 / 6 / 3 android里面crash特别是系统级别的会常见。
