OS module in Python provides functions for interacting with the operating system. OS comes under Python’s standard utility modules. This module provides a portable way of using operating system dependent functionality.
All functions in os module raise
OSError in the case of invalid or inaccessible file names and paths, or other arguments that have the correct type, but are not accepted by the operating system.
os.chown() method in Python is used to change the
owner and
group id of the specified path to the specified numeric
owner id (UID) and
group id (GID).
Note: os.chown() method is available only on UNIX platforms and the functionality of this method is typically available only to the superuser or a privileged user.
Syntax: os.chown(path, uid, gid, *, dir_fd = None, follow_symlinks = True)
Parameters:
path: A file descriptor representing the file whose uid and gid is to be set
uid: An integer value representing the owner id to be set for the path.
gid: An integer value representing the group id to be set for the path. To leave any one of the ids unchanged, set it to -1.
dir_fd (optional): A file descriptor referring to a directory. The default value of this parameter is None.
follow_symlinks (optional): The default value of this parameter is True. If we do not want os.chown() method to follow symlink, we can set it to False. If it is False, method will operate on the symbolic link itself instead of the file the link points to.
Note: The ‘*’ in parameter list indicates that all following parameters (Here in our case ‘dir_fd’ and 'follow_symlinks') are keyword-only parameters and they can be provided using their name, not as a positional parameter.
Return Type: This method does not return any value.
Code #1: Use of os.chown() method
Output:
👁 os.chown() method terminal output
Code #2: Use of os.chown() method to set any one id and leave other unchanged
Output:
👁 os.chown() method terminal output
Code #3: If the specified path is a symlink
