What Is The Multiplatform Alternative To Subprocess.getstatusoutput (older Commands.setstatusoutput() From Python?

The code below is outdated in Python 3.0 by being replaced by subprocess.getstatusoutput(). import commands (ret, out) = commands.getstatusoutput('some command') print ret print o

Solution 1:

I wouldn't really consider this multiplatform, but you can use subprocess.Popen:

import subprocess
pipe = subprocess.Popen('dir', stdout=subprocess.PIPE, shell=True, universal_newlines=True)
output = pipe.stdout.readlines()
sts = pipe.wait()
print sts
printoutput

Here's a drop-in replacement for getstatusoutput:

defgetstatusoutput(cmd): 
    """Return (status, output) of executing cmd in a shell.""""""This new implementation should work on all platforms."""import subprocess
    pipe = subprocess.Popen(cmd, shell=True, universal_newlines=True,
            stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
    output = str.join("", pipe.stdout.readlines()) 
    sts = pipe.wait()
    if sts isNone:
        sts = 0return sts, output

This snippet was proposed by the original poster. I made some changes since getstatusoutput duplicates stderr onto stdout.

The problem is that dir isn't really a multiplatform call but subprocess.Popen allows you to execute shell commands on any platform. I would steer clear of using shell commands unless you absolutely need to. Investigate the contents of the os, os.path, and shutil packages instead.

import os
import os.pathfor rel_name inos.listdir(os.curdir):
  abs_name = os.path.join(os.curdir, rel_name)
  ifos.path.isdir(abs_name):
    print('DIR:  ' + rel_name)
  elif os.path.isfile(abs_name):
    print('FILE: ' + rel_name)
  else:
    print('UNK?  ' + rel_name)
