[英]Getting Python to kill a pid
This is the current code I have right now and I'm wondering how I can get it to kill the pid. 这是我现在拥有的当前代码,我想知道如何获取它以杀死pid。
import commands, signal
stuid = commands.getoutput("pgrep student")
deaid = commands.getoutput("pgrep daemon")
print stuid
os.kill(stuid, signal.SIGKILL)
print deaid
os.kill(deaid, signal.SIGKILL)
Edit: So, in the end, I just used os.system to get the terminal to run the kill command then place the pid after kill. 编辑:因此,最后,我只是使用os.system来使终端运行kill命令,然后将pid放在kill之后。
import commands, os
stuid = commands.getoutput("pgrep student")
deaid = commands.getoutput("pgrep daemon")
print stuid
os.system("kill "+stuid)
print deaid
os.system("kill "+deaid)
Overall this is my end result. 总的来说,这是我的最终结果。 Hope this helps people in the future. 希望这对以后的人们有所帮助。

BTW a more pythonic solution may be this: 顺便说一句,更pythonic解决方案可能是这样的:
import re
import psutil
convicted = re.compile(r'student|daemon')
for p in psutil.process_iter():
if convicted.search(p.name):
p.terminate()
Edit: To be more accurate I changed the line p.kill()
to p.terminate()
. 编辑:为了更准确,我将行p.kill()
更改为p.terminate()
。 The common kill
in bash is actually the same as p.terminate()
(it sends the TERM signal). 常见kill
在bash实际上是一样的p.terminate()
它发送TERM信号)。 But the p.kill()
corresponds to kill -9
in bash (it sends the KILL signal). 但是p.kill()
相当于在bash中kill -9
(它发送KILL信号)。
