Command Documentation (help)

help [ command [ subcommand ]

Get help for a debugger command or subcommand.

Without an argument, print the list of available debugger commands.

When an argument is given, it is first checked to see if it is command name.

Some commands like info, set, and show can accept an additional subcommand to give help just about that particular subcommand. For example help set basename give help about the basename subcommand of set.
