To slap all ports into the same bridge
foreach i in=[interface find] do={interface bridge port add interface=$i bridge=(YOUR BRIDGE INTERFACE)}
this was another script from the other day, someone wanted x vlans in the bridge>vlans config that were concurrent, idk if you can make some use out of it as well, count will be the start, will go up 1 vlan per run, either add the other ports in the tagged= or alternatively have some fun and see if you can incorporate some of the code into that so you dont have to
local count (number here at the vlan you want to start at)
foreach i in=[interface bridge vlan find] do={ local vn [interface bridge vlan find vlan-ids=$count] ; interface bridge vlan set numbers=$vn tagged=ether1,ether2,ether3,ether4,ether5; if ($count<=10) do=[set count ($count + 1)] }
