14. Alter File Owner and Group

Write a Python program to alter the owner and the group ID of a specified file.

Sample Solution:

Python Code :

import os
fd = os.open( "/tmp", os.O_RDONLY )
os.fchown( fd, 100, -1)
os.fchown( fd, -1, 50)
print("Changed ownership successfully..")
os.close( fd )

Sample Output:

Traceback (most recent call last):
  File "/tmp/sessions/a24dd3f1f2e68f39/main.py", line 3, in 
    os.fchown( fd, 100, -1)
PermissionError: [Errno 1] Operation not permitted

• Write a Python function that accepts a file path and new owner and group IDs, updates the file’s ownership, and returns a confirmation message.
• Write a Python script to alter the owner and group of a file and then use os.stat() to verify and display the updated metadata.
• Write a Python program to attempt changing a file's owner and group, handling exceptions if the operation is not permitted, and printing the error message.

Previous: Write a Python program to join one or more path components together and split a given path in directory and file.
Next: Write a Python program to get information about the file pertaining to the file mode. Print the information - ID of device containing file, inode number, protection, number of hard links, user ID of owner, group ID of owner, total size (in bytes), time of last access, time of last modification and time of last status change.
