What is the difference between chmod and chown?

The difference between chmod and chown lies in their functions related to file permissions and ownership:

• chmod (Change Mode): This command is used to change the permissions of a file or directory. It allows you to specify who can read, write, or execute the file. Permissions can be set using symbolic notation (like u+x for adding execute permission for the user) or numeric notation (like 755).

• chown (Change Owner): This command is used to change the ownership of a file or directory. It allows you to specify a new owner (user) and optionally a new group for the file. For example, chown user:group filename changes the owner to user and the group to group.

In summary, chmod modifies file permissions, while chown changes the ownership of files or directories.
