How do I manage user permissions in Linux?

In Linux, you can manage user permissions using the chmod, chown, and chgrp commands. Would you like a brief overview of each?

Yes, please explain chmod.

chmod changes the file mode (permissions) of a file or directory. You can use symbolic or numeric modes. For example, chmod 755 filename gives the owner full permissions and read/execute permissions to others.

What about chown?

chown changes the ownership of a file or directory. For instance, chown user:group filename changes the owner to 'user' and the group to 'group'.

Can you give me an example of using chgrp?

Sure! chgrp groupname filename changes the group ownership of 'filename' to 'groupname'. This is useful for managing group access.
