text file 1 has 5000 unique lines, text file 2 has 500 unique lines
I want to remove each *entire line* containing the data on text file 2, from file 1, leaving me 4500 lines
!I don't know php!
!I barely know excel (well, open office) but if it's doable in that I can follow simpleton instructions

!
Ideally an online place similar to textmechanic.com, where I load one, load the other, and hey presto.
thanks in advance, and I might even thank you again afterwards for double the fun
