用Python的subprocess模块来执行Linux命令

 

这个函数会执行类似于 ps aux | grep python | awk '{print $2}' | xargs kill -9 的Linux命令。你可以将参数 process_name 替换为你想要杀死的进程名。

 

 

import subprocess

def kill_process(process_name):
    p1 = subprocess.Popen(["ps", "aux"], stdout=subprocess.PIPE)
    p2 = subprocess.Popen(["grep", process_name], stdin=p1.stdout, stdout=subprocess.PIPE)
    p3 = subprocess.Popen(["awk", "{print $2}"], stdin=p2.stdout, stdout=subprocess.PIPE)
    p4 = subprocess.Popen(["xargs", "kill", "-9"], stdin=p3.stdout)
    p1.stdout.close()
    p2.stdout.close()
    p3.stdout.close()
    output, error = p4.communicate()
    if error:
        print(f"Error: {error}")
    else:
        print(f"Process {process_name} killed successfully.")

# Example usage
kill_process("python")

 

 

 

 

import subprocess

# 构建命令
command = 'curl http://localhost:6800/schedule.json -d project=abc'

# 运行命令
p = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE)

# 获取输出
out, err = p.communicate()

# 输出结果
print(out.decode('utf-8'))
