Linux下使用指令結束程序

有時候某個軟體卡死，想直接Kill掉。

1.ps -ef  或者 ps -aux 檢視目前所有的程序：

xxxx:project/ $ ps -ef                                                                                                   [0:32:26]
UID        PID  PPID  C STIME TTY          TIME CMD
root         1     0  0 Sep13 ?        00:00:00 /sbin/init
root         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 COMMAND
root         1  0.0  0.0  34032  4592 ?        Ss   Sep13   0:00 /sbin/init
           

PID is the processID

3. ps -ef或者ps -aux 兩者列出來的程序都比較多，我們可以過濾。然後找到pid直接kill掉該程序。

xxxx:project/ $ ps -ef | grep firefox                                                                                    [0:39:56]
xxxx   3027  1753  1 Sep13 ?        00:02:09 /usr/lib/firefox/firefox
xxxx  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 是專門用于程序查詢的

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

如果這裡能直接查出pid則，我們後面使用管道符号，直接幹掉該程序

     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   查詢

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     
           

各種信号的含義：常見的有signal 11 / 9 / 6 / 3  android裡面crash特别是系統級别的會常見。
