python3 進程中 獲取進程號和殺死進程

轉載：https://blog.csdn.net/Teddycxr/article/details/80804383

 

遍歷搜尋及測試總結三種方法：

 

1. signal

import os,signal

out=os.popen("ps aux | grep xx.py").read()

for line in out.splitlines():
    print(line)
    if 'BcexServices.py' in line:
        pid = int(line.split()[1])
        print(pid)
    os.kill(pid,signal.SIGKILL)

def kill(pid):
    try:
        a = os.kill(pid, signal.SIGKILL)
        print('已殺死pid為%s的進程,　返回值是:%s' % (pid, a))

    except OSError:
        print('沒有如此進程!!!')

2. psutil

import psutil

def processinfo(processName):
    pids = psutil.pids()
    for pid in pids:
        # print(pid)
        p = psutil.Process(pid)
        # print(p.name)
        if p.name() == processName:
            print(pid)
            return True  # 如果找到該進程則打印它的PID，返回true
    return False  # 沒有找到該進程，返回false

processinfo('你的文件名.py')

3. psutil 的另外一種方式

for proc in psutil.process_iter():
    print("pid-%d,name:%s" % (proc.pid,proc.name()))
