@rollback

@rollback <count>[/<repeats>][=<arg0>[,...[,<argN>]]]
@rollback/retry <boolean>[=<arg0>[,...[,<argN>]]]

@rollback runs the commands before it in the same action list again. <count> is how many of them, counting back from the @rollback, and <repeats> how many times (1 unless given). A count of 0, or one with nothing before it, does nothing; a count larger than the list takes the whole list.

@rollback/retry runs every command before it again while <boolean> is true.

The arguments become %0-%9 for each run, evaluated before every run with the %0-%9 of the run before. The list then goes on with its own %0-%9. One @rollback runs at most 1,000 times. The RhostMUSH switches /wait and /label are not supported.
