Question

import sys
import os

log = os.system('cat /var/log/demesg')

This code prints the file by running the shell script cat /var/log/dmesg. However, it is not copied to the log. I want to use this data somewhere else or just print the data like print log.

How can I implement this?

Answer 1

Simply read from the file yourself:

with open('/var/log/dmesg') as logf:
    log = logf.read()
print(log)
