mk90.commands

Command help

List command names or display the compact guide for one command.

Synopsis

help [command]

Ordinary invocation: foreground child, PID 3; the shell waits. Allowed as a pipe producer.

Parameters

Parameter	Meaning
`command`	Optional registered command name; case-insensitive.

Description

With no argument, prints the 33 registered names and the reminder help cmd. With one valid name, reads and verifies that command’s guide from the boot ROM.

HELP is dispatched as an ordinary foreground application, using the same registry as the other commands. Its on-device guide is deliberately short; this manual supplies the full reference.

Examples

help
help mbc
help ls

Limits and side effects

There is no on-device full-text search. A filename is not a help topic.

Status and diagnostics

Success is status 0. Relevant status codes: 8, 13, 19. See the diagnostic reference.
