banner exec d message-text d

no banner exec

Parameters

• d—Delimiting character of user’s choice—a pound sign (#), for example. You cannot use the delimiting character in the banner message.

• message-text—The message must start in a new line. You can enter multi-line messages. You can include tokens in the form of $(token) in the message text. Tokens are replaced with the corresponding configuration variable (see User Guidelines). The message can contain up to 1000 characters (after every 510 characters, press <Enter> to continue).
