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())
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, in
os.setuid(uid) PermissionError: [Errno 1] Operation not permitted
