[PLUG] A Linux Tool To Compare Files of Different Sizes

[Rich Shepard]

   Thought I had found such a tool once but I no longer remember its name.
Here's the situation:

   Two files: one with 474 lines, the other with 203 lines. I want to test
whether all 203 lines of the second file are included in the first file. If
not, I want a list of those second file lines not found in the first file.

   A cluestick is needed.

TIA,

Rich
