I'm using python 3.7 on Windows. I'm trying to execute a simple scan command and get its output as a string.
When I execute the command in python I only get the first line:

import subprocess



def execute(command):

    proc = subprocess.run(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE, universal_newlines=True)

    output = proc.stdout if proc.stdout else proc.stderr



path = "Somepath"

command = ['ecls.exe', '/files', path]

print(execute(command))

WARNING! The scanner was run in the account of a limited user.

But when I run it in the CMD:

ecls.exe /files "SomePath" WARNING! The scanner was run in the account
of a limited user.

ECLS Command-line scanner ...

Command line: /files SomePath

Scan started at: 11/24/18 14:18:11

Scan completed at: 11/24/18 14:18:11 Scan time: 0 sec
(0:00:00) Total: files - 1, objects 1 Infected:

files - 0, objects 0 Cleaned: files - 0, objects 0

I think that the command spawn a child process and it produces the scan output. I also tried to iterate over stdout but got the same output.

EDIT:
I tried other methods like check_output, Popen, etc with using PIPE but I only get the first line of output. I also tried to use shell=True but didn't make any difference. As I already said the command spawn a child process and I need to capture its output which seems that subprocess can't do it directly.

As I couldn't find a direct way to solve this problem, with help of this reference, the output can be directed to a text file and then read it back.

import subprocess

import os

import tempfile



def execute_to_file(command):

    """

    This function execute the command

    and pass its output to a tempfile then read it back

    It is usefull for process that deploy child process

    """

    temp_file = tempfile.NamedTemporaryFile(delete=False)

    temp_file.close()

    path = temp_file.name

    command = command + " > " + path

    proc = subprocess.run(command, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE, universal_newlines=True)

    if proc.stderr:

        # if command failed return

        os.unlink(path)

        return

    with open(path, 'r') as f:

        data = f.read()

    os.unlink(path)

    return data



if __name__ == "__main__":

    path = "Somepath"

    command = 'ecls.exe /files ' + path

    print(execute(command))
