Code of Civil Procedure section 1087

The writ may be either alternative or peremptory. The alternative writ must command the party to whom it is directed immediately after the receipt of the writ, or at some other specified time, to do the act required to be performed, or to show cause before the court at a time and place then or thereafter specified by court order why he has not done so. The peremptory writ must be in a similar form, except that the words requiring the party to show cause why he has not done as commanded must be omitted.
