The HELP command provides online information about the VOLUTIL commands. When used by itself, the command displays a list of available commands and a brief syntax of each command. When HELP is used with a command name (for example, HELP SHOWSET), HELP displays detailed information about the particular command, along with a detailed syntax diagram for the command and an example of its use.
