If I'm understanding you correctly, you have lets say an array of keys 
you want to find in a file.

fileKeys = ["key1","key44","key5"]

lets just say the file contains a bunch of useless jargon and some keys:

testfile.txt #

stuff
more stuff
key5
useless junk
more useless junk
not a key
key44


Ok, now lets read that file and put the keys in an array called results

results = []

IO.foreach("testfile.txt") {|x| results << x.chomp}
=> nil

Now we compare the arrays to find any matches

results&fileKeys
=> ["key5","key44"]
