How to pass output of a command in cmd to a txt file using python?

Question

Is there a way through which I can pass the output of a CMD command to a .txt file using python?

Something like this:

 import os
 os.system('cmd /c "netsh wlan show profiles"')
 #output=OUTPUT
 output_file=open(outputfile+'.txt','w')
 output_file.write(OUTPUT)
 output_file.close()

Is there a way to do this?

Answer 1

import subprocess
out = subprocess.getoutput("ls -l")
print(out)

Now you can just pass on this output to a txt file using open() and file.read() method

Answer 2

You can just pass the output to a temporary file. The following is a simple example:

import os
os.system('cmd /c "netsh wlan show profiles" > tmp.txt')

Then you can just read the tmp.txt file and see the output. This solution is based on your code.

There are other options such as using subprocess , you can read more in the following link: https://docs.python.org/3/library/subprocess.html#using-the-subprocess-module

Answer 3

Try this library https://docs.python.org/3/library/subprocess.html

Method subprocess.run() should do the job. It allows to capture stdout and stderr when param capture_output=True

Answer 4

There is already a similar question here: Running shell command and capturing the output

import subprocess
output = subprocess.check_output(["echo", "Hello, World!"])
