from subprocess import Popen, PIPE, STDOUT p = Popen(cmd, stdout=PIPE, stderr=STDOUT, shell=True) while True: print(p.stdout.readline()) if not line: break 但是由于子程序没有进行 flush 的话,会把结果缓存到系统中。导致程序运行完成,上面的程序才会进行打出(会一直卡在readline这个函数)。 解...

os.popen(cmd, mode='r', buffering=-1) Open a pipe to or from command cmd. The return value is an open file object connected to the pipe, which can be read or written depending on whether mode is 'r' (default) or 'w'. The buffering argument has the same meaning as the correspond...

Wait for child process to terminate. Returns returncode attribute. terminate() 杀掉所启动进程 communicate() 等待任务结束 stdin 标准输入 stdout 标准输出 stderr 标准错误 pid The process ID of the child process. Popen例子: p = subprocess.Popen("df -lh|grep root",stdin=subproce ...
1、Popen.pid 获取子进程的进程ID。 2、Popen.returncode 获取进程的返回码。如果进程未结束,将返回None。 3、communicate(input=None) 官方解释: Interact with process: Send data to stdin. Read data from stdout and stderr, until end-of-file is reached. Wait for ...
os.popen 1.如果想获取控制台输出的内容,那就用os.popen的方法了,popen返回的是一个file对象,跟open打开文件一样操作了,r是以读的方式打开 代码语言:javascript 代码运行次数:0 运行 AI代码解释 # coding:utf-8importos # popen返回文件对象,跟open操作一样 ...
