Linux下使用命令结束进程
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 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/initPID 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/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。
