Export command line output to a file in Python -


here's code execute jar file in python:

import os os.system("java -jar xyz.jar")

i can see output on terminal, want store in file. how can that?

with subprocess.call can pipe outputs (stdout, stderr or both) directly file:

import subprocess subprocess.call("java -jar xyz.jar", shell=true, stdout=open('outfile.txt', 'wt'), stderr=subprocess.stdout)

note added shell=true parameter, required if application requires shell-specific variables (such java located).

also note in above call, output streams handled follows:

  • stderr stream piped stdout, and
  • stdout piped outfile

more details on stream configurations available in subprocess manual page.
