Copy Selected Lines

I have two sheets.
sheet 1 has a list of invoices.
on sheet 2 I just want to list certain invoices.

so sheet 1 may be like this:

001 rmb $25.00 1356
002 ght $35.02 4568
003 ght $45.23 5689
004 rmb $12.25 4568
005 bnj $1.25 4568
006 sdr $12.54 4568
007 rmb $65.25 4568
009 bnj $56.54 4568


On sheet 2 I need it to pull out all the rmb lines.

001 rmb $25.00 1356
004 rmb $12.25 4568
007 rmb $65.25 4568

I could make sheet 2 in to a list and sort it that way. but what I
need to do is pull the information into sheet 2, it's no good being
able to sort it on sheet 1.
