If the directory cannot be created, you are again warned and given the option of continuing with the session anyway (again, by typing a single 'c' when asked).

So, while nweb is still running in another xterm session, halt the strace by pressing Ctrl + c, and then launch the GDB Debugger by typing the commands shown in Listing 5.

You can do this by initiating a CLI session and passing the appropriate command with the -c argument.
