How to capture output from bourne shell command

Question

我想执行一个 bourne shell 命令，捕获它的 stdout 和它的 stderr（单独），以及它的退出代码。

Answer 1

You can use subprocess (part of stdlib):

import subprocess

cmd = input("enter your command: " )
result = subprocess.run(cmd, stdout = subprocess.PIPE, stderr = subprocess.PIPE, universal_newlines = True)
print("stdout = %s" % (result.stdout))
print("stderr = %s" % (result.stderr))
print("return = %d" % (result.returncode))
