Python Operating System Services: Exercise-8 with Solution
Write a Python program to find the parent’s process id, real user ID of the current process and change real user ID.
Sample Solution:
Python Code :
import os
print("Parent’s process id:",os.getppid())
uid = os.getuid()
print("\nUser ID of the current process:", uid)
uid = 1400
os.setuid(uid)
print("\nUser ID changed")
print("User ID of the current process:", os.getuid())
Sample Output:
Parent’s process id: 11069 User ID of the current process: 1000 Traceback (most recent call last): File "/tmp/sessions/caaafe2b92f1fb7d/main.py", line 6, inos.setuid(uid) PermissionError: [Errno 1] Operation not permitted
