what is the equivalent option for Fabric OS command on brocade to include only certain string like a grep or include

I am very familiar with cisco NXOS commands for switches but new on the Brocade Fabric OS CLI. I am doing a switchshow or zoneshow/configshow but only want to show certain strings like to show only certain aliases on the configshow or the zoneshow.

My command is zoneshow and I want to pipe it to like "grep" (on unix) or "include" (Cisco NXOS). what is the equivalent of grep or include on Fabric OS commands?

Thank you.
