sub_process = subprocess.Popen(command, stdin = subprocess.PIPE,stdout = subprocess.PIPE,stderr = subprocess.PIPE, shell = True) 为了搞清楚subprocess是怎么获取子进程stdout的,我们首先看看 subprocess.PIPE是什么 进入代码里可以看见subprocess.PIPE 直接是个int -1 再看看网上一般获取subprocess回显的代码 点...
subprocess.run(['dir'], timeout=2) 4.常用方法和函数 run(cmds,shell=True,text=True,stdout=subprocess.PIPE, stderr=subprocess.PIPE): 执行指定的命令,stdout和stderr参数来捕获子进程的输出。 Popen(args, stdout=subprocess.PIPE): 创建一个新的子进程对象。 communicate(input): 与子进程进行交互,...
stdout: print(line, end='') # 直接打印输出,保留了颜色 _run_cmd_res = process.wait() return _run_cmd_res, "" def run_cmd(cmd): process = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT) try: out, _err = process.communicate() r = process.return...
>>> res = subprocess.Popen("lm -l",shell=True,stdout=subprocess.PIPE,stderr=subprocess.PIPE) >>> res.stderr.read() #标准输出错误 '/bin/sh: lm: command not found\n' >>> obj.stderr.close() #关闭启动程序的标准错误 1. 2. 3. 4. 5. 注意:上面的提到的标准输出都为啥都需要等于subpr...
subprocess模块的官方文档在这里,最核心的单位是subprocess.Popen类,它描述了一个正在运行中的进程。subprocess最基础的用法是subprocess.run,我们入参一段cmd终端命令,run方法内部就会启动一个Popen对象执行这个命令,等待命令执行结束后,返回这个命令执行的退出码retcode,标准输出流内容stdout以及标准错误流内容stderr。我们可...
subprocess.check_call() subprocess.check_call(args, *, stdin = None, stdout = None, stderr = None, shell = False) 与call方法类似,不同在于如果命令行执行成功,check_call返回返回码0,否则抛出subprocess.CalledProcessError异常。 subprocess.CalledProcessError异常包括returncode、cmd、output等属性,其中retu...
if not subprocess.Popen.poll(proc) is None: if line == "": break proc.stdout.close() 记小的写法 proc = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT) try: while True: buff = proc.stdout.readline() ...
The new process has a new console, instead of inheriting its parent’s console (the default). This flag is always set when Popen is created with shell=True. subprocess.CREATE_NEW_PROCESS_GROUP A Popen creationflags parameter to specify that a new process group will be created. ...
