Python 捕获命令发送到 unix，捕获输出并写入文件

Question

import subprocess 
cmd = 'ifconfig -a'

p = subprocess.Popen(cmd, shell=True, stderr=subprocess.PIPE)

while True:
    out = p.stderr.read(1)
    if out == '' and p.poll() != None:
        break
    if out != '':
        sys.stdout.write(out)
        sys.stdout.flush()
       <<<HOW TO CMD SENT AND IT'S OUTPUT>>>
        file = open('outputFile.txt', 'w+')
        file.write(out)
        file.close()

Answer 1

from subprocess import Popen, PIPE, STDOUT
cmd = ["ifconfig", "-a"]

p = Popen(cmd, stdout=PIPE, stderr=STDOUT)
stdout, stderr = p.communicate()

print stdout

捕获输出并写入文件：python ifconfig.py > outputfile.txt

Python 捕获命令发送到 unix，捕获输出并写入文件

Python capture command send to unix, capture output and write to file

python

unix

command

file
