Using a shell script to automatically kill processes
提问by verystrongjoe
I am looking for a command that will find PIDs such as:
我正在寻找一个可以找到 PID 的命令，例如：
ps -ef | grep com.sds.afi.rte.cosmos-1.0.0.jar
cosmos 4690 4689 3 14:27 pts/8 00:00:06 java -Dlog4j.debug -Dlog4j.configuration=file:/data/cosmos/sim/bin/log4j.xml -jar com.sds.afi.rte.cosmos-1.0.0.jar
cosmos 5484 5482 0 14:30 pts/11 00:00:00 grep com.sds.afi.rte.cosmos-1.0.0.jar
and then kill these processes using:
然后使用以下命令终止这些进程：
kill -9 pid
How can I make a shell script that will do all the above automatically ?
如何制作一个可以自动完成上述所有操作的 shell 脚本？

Try this:
尝试这个：
kill -9 `pidof java`
回答by ErJab
killall java
killall java
Or more generically:
或更笼统地说：
killall <processname>
killall <processname>
Sometimes I have processes with the same name, but different command line arguments. To kill such processes or any arbitrary process without having to type in ps and then kill pid, I do this:
有时我的进程名称相同，但命令行参数不同。要终止此类进程或任何任意进程而不必输入 ps 然后终止 pid，我这样做：
ps aux | grep <something> | awk '{print $2}' | xargs kill
ps aux | grep <something> | awk '{print $2}' | xargs kill
where
在哪里
<something>is any phrase that you want to search for in the ps aux command's output.awk '{print $2}'will filter out only the 2nd column, which is a list of PIDskillwill be called on each of those PIDs.
<something>是您要在 ps aux 命令的输出中搜索的任何短语。awk '{print $2}'将仅过滤掉第二列，即 PID 列表kill将在每个 PID 上调用。
Edit: As tripleee points out, it is a bad idea to lash out kill -9on a process unless absolutely needed. So removed the -9part from the above command
编辑：正如三重奏指出的那样，kill -9除非绝对需要，否则对流程进行猛烈抨击是一个坏主意。所以-9从上面的命令中删除了部分

I think pkill -9 javais the easiest way. pkillwill use grep to find a matching process name.
我认为pkill -9 java是最简单的方法。pkill将使用 grep 查找匹配的进程名称。
See the manual page: http://linux.die.net/man/1/pkill

In addition to the solution ErJabprovided, I created a shell script killall to mimic the 'killall' behaviour:
除了ErJab提供的解决方案之外，我还创建了一个 shell 脚本 killall 来模仿“killall”行为：
#!/bin/sh
ps | grep | awk '{print }' | xargs kill -9
Which I placed in the /bin directory (after chmod +x, of course)
我放在 /bin 目录中（当然是在 chmod +x 之后）

I find the pkill/pgrepcommands as mentioned by nikeairjthe best choice if available.
I also used the following which may also work in Linux/Unix OSes without awkor other possibly unavailable commands(I remember not beeing able to use awkin some AIXor HP-UXenvironments)
如果可用，我会找到最佳选择中提到的pkill/pgrep命令nikeairj。我还使用了以下也可以在没有awk或其他可能不可用的命令的Linux/Unix 操作系统中工作（我记得不能awk在某些AIX或HP-UX环境中使用）
# subsitute myMatch with your process cmdline match, e.g. "firefox", "firefox -P"
# or anything output by "ps -ef"
ps -ef|grep myMatch|grep -v grep|sed -e "s/^[^0-9]\+\([0-9]\+\)\s.\+$//"|xargs kill "{}"

You can include below command in your shell script which will kill the process id for "com.sds.afi.rte.cosmos-1.0.0.jar"
您可以在 shell 脚本中包含以下命令，该命令将终止“com.sds.afi.rte.cosmos-1.0.0.jar”的进程 ID
kill -9 ps aux | grep com.sds.afi.rte.cosmos-1.0.0.jar | grep -v grep | awk '{print \$2}'
杀 -9 ps aux | grep com.sds.afi.rte.cosmos-1.0.0.jar | grep -v grep | awk '{print \$2}'
make sure you use inverted (``) comma for pid search as used above.
确保使用倒置的 (``) 逗号进行 pid 搜索，如上所述。
if you want to execute the above command from expect command then you can use below:
如果要从 expect 命令执行上述命令，则可以使用以下命令：
expect "$"
期待“$”
send "kill -9 ps aux | grep com.sds.afi.rte.cosmos-1.0.0.jar | grep -v grep | awk '{print \$2}'\r"
发送“kill -9 ps aux | grep com.sds.afi.rte.cosmos-1.0.0.jar | grep -v grep | awk '{print \$2}'\r”
Cheers, Suraj
干杯，苏拉杰

I made a .sh to restart my Wifi after putting it in monitor mode with the following lines.
在使用以下几行将其置于监控模式后，我制作了一个 .sh 以重新启动我的 Wifi。
#Display PID
echo "Killing network PID'S"
ps aux | grep wpa_supplicant | awk '{print }' | xargs kill
ps aux | grep NetworkManager | awk '{print }' | xargs kill
#Restart NetworkManager && wpa_supplicant
echo "Restarting NetworkManager && wpa_supplicant"
service NetworkManager restart && service wpa_supplicant restart
