What are symbolic permissions in chmod?

Can you explain what symbolic permissions are in chmod?

Sure! Symbolic permissions in chmod allow you to set file permissions using letters instead of numbers. You can use 'r' for read, 'w' for write, and 'x' for execute.

How do I add execute permission for a user using symbolic notation?

You can add execute permission for a user by using the command chmod u+x filename, where 'u' stands for user.

What if I want to remove write permission for a group?

You would use the command chmod g-w filename, where 'g' stands for group.

Can I set permissions for multiple users at once?

Yes, you can combine permissions. For example, chmod ug+rw filename adds read and write permissions for both user and group.
