!for_each_frame is a favorite among debuggers. It's a very flexible and powerful command that enables you to run commands for each frame of the call stack.

You can use basically any command.

For instance, let’s say you want to see all local variables from each frame of a specific stack. Of course, to see local variables you must have private symbols.
