Your CLI is up-to-date.

Howdy jlausuch, is this new to 2.0.68 or has this behavior been present for older versions as well?

I suspect that the terminal you're using isn't playing nice with our colorizer. It would explain why an unexpected control character is being output, and also why it doesn't happen when you're not using an interactive terminal session.

[jlausuch]

It didn't happen with version 2.0.64 actually.

I have the same problem in pycharm.The version is 2.0.69.

[marstr]

@charlesguoooo, is your platform also SUSE?

[charlesguoooo]

@marstr no, It was happened in pycharm on mac. look this

#!/usr/bin/env python

import re
import json
import subprocess

result = subprocess.check_output(["az account show"],shell=True)

print json.dumps(result)

# return result include \u001b[0m in the end

But if not in pycharm,Just run python test.py,the return result is right

I'm going to unassign myself, as this does not relate to the Packaging as originally believed. @zikalino, @yugangw-msft you guys may want to re-triage or re-assign this.
