What is the symbolic notation for chmod?

The symbolic notation for chmod is used to change file permissions in Unix-like systems. It consists of three parts: user (u), group (g), and others (o). You can use symbols like + (add), - (remove), and = (set) to modify permissions.

Can you give me an example of how to use it?

Sure! If you want to give the user permission to read and write a file, you would use: chmod u+rw filename. This adds read and write permissions for the user.

What if I want to remove execute permission for others?

You can do that with: chmod o-x filename. This command removes the execute permission for others.

Is there a way to set permissions for all at once?

Yes! You can use chmod a+rwx filename to give read, write, and execute permissions to everyone (user, group, and others) at once.
