Hi Dan,

perhaps something like this is what you want?

synack@eugene:~/tmp/fox-0.99.166/textedit$ cat > testFile
line 1
line 2
line 3
synack@eugene:~/tmp/fox-0.99.166/textedit$ irb
irb(main):001:0> f = File.new("testFile")
#<File:0x402281d4>
irb(main):002:0> f.readlines.reverse.each { |line| p line }
"line 3\n"
"line 2\n"
"line 1\n"
["line 3\n", "line 2\n", "line 1\n"]

Hope this helps you some.
