8.8 ? (List all commands / command specific help)

8.8.1 Function

The “?” command is an alias for the “help” command. Without any options it will display a sorted list of all
commands matching the current command level with a short description. It is possible to specify a partial
command name followed by an asterisk (“*”) to get a list of all commands matching the partial command
name. For example ‘? msg*’ will list all commands beginning with ‘msg’ and matching the current com-
mand level.

If the list is enterd with a full command name it will display a long form of help information associated with
that command if the command is available for the current command level. The list provided by the com-
mand without options shows with an asterisk in front of the description if there is additional information
available.

The displayed help text may be limited to explaining the general format of the command and its various
required or optional parameters and is not meant to replace the appropriate manual.
