How does chown command work internally in Linux?

The chown command in Linux is used to change the ownership of files and directories. It allows users to specify a new owner and, optionally, a new group for the specified file(s). Internally, the command interacts with the filesystem to update these attributes.

When executed, the chown command performs the following:

• It checks the permissions of the user attempting to make the change to ensure they have the necessary rights.
• The command retrieves the current ownership information of the file(s) from the filesystem.
• It updates the inode structure of the file(s) to reflect the new owner and group, ensuring the changes are reflected in the filesystem.
• Finally, it provides feedback to the user about the success or failure of the operation.

Here is an example of the chown command:
