在 bash 中终止进程

如何终止在 bash 中运行的进程——例如，假设我打开一个文件:

$gedit file. txt

有没有办法在命令提示符内关闭它？这个示例相当琐碎，因为我可以只关闭窗口，但它似乎有点出现，特别是当我输入错误的命令时。

另外，是否有办法转义正在运行的可执行文件？这可能有相同的解决方案，但我认为我会问。

谢谢

You have a multiple options:

First, you can use kill. But you need the pid of your process, which you can get by using ps, pidof or pgrep.

ps -A  // to get the pid, can be combined with grep
-or-
pidof <name>
-or-
pgrep <name>


kill <pid>

It is possible to kill a process by just knowing the name. Use pkill or killall.

pkill <name>
-or-
killall <name>

All commands send a signal to the process. If the process hung up, it might be neccessary to send a sigkill to the process (this is signal number 9, so the following examples do the same):

pkill -9 <name>
pkill -SIGKILL <name>

You can use this option with kill and killall, too.

Read this article about controlling processes to get more informations about processes in general.

You can use the command pkill to kill processes. If you want to "play around", you can use "pgrep", which works exactly the same but returns the process rather than killing it.

pkill has the -f parameter that allows you to match against the entire command. So for your example, you can: pkill -f "gedit file.txt"

try kill -9 {processID}

To find the process ID you can use ps -ef | grep gedit

It is not clear to me what you mean by "escape an executable which is running", but ctrl-z will put a process into the background and return control to the command line. You can then use the fg command to bring the program back into the foreground.

To interrupt it, you can try pressing ctrl c to send a SIGINT. If it doesn't stop it, you may try to kill it using kill -9 <pid>, which sends a SIGKILL. The latter can't be ignored/intercepted by the process itself (the one being killed).

To move the active process to background, you can press ctrl z. The process is sent to background and you get back to the shell prompt. Use the fg command to do the opposite.

Old post, but I just ran into a very similar problem. After some experimenting, I found that you can do this with a single command:

kill $(ps aux | grep <process_name> | grep -v "grep" | cut -d " " -f2)

In OP's case, <process_name> would be "gedit file.txt".

Please check "top" command then if your script or any are running please note 'PID'

PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
1384 root      20   0  514m  32m 2188 S  0.3  5.4  55:09.88 example
14490 root      20   0 15140 1216  920 R  0.3  0.2   0:00.02 example2






kill <you process ID>


Example : kill 1384

This one is violent use with caution : 

pkill -9 -e -f processname

If your process name is "sh" it will also kill "bash"
