Yes, this is a technique I've used when doing up important (and
dangerous) MUD commands. The command will be something like "unload
foo" and it gives its first-time spam, or "unload confirm foo" to
suppress it and go straight to the potentially-dangerous action. With
shell commands, a -f or --force parameter would be common for that.
