blockFile = File.new("blocklist.txt", "a+")
print blockFile.read.include?("aa")
blocklist.txt looks like
--------------------------------------------
aa
ae
aj
au
ae
---------------------------------------------
Why does #include? return true on the first call only?
Thank you,

Because you've reached end-of-file

blockFile = File.new("blocklist.txt", "a+")
print blockFile.read.include?("aa")
blockFile.lineno = 0
print blockFile.read.include?("aa")
Still gives true false instead of true true

I'm ignorant of #lineno= but it doesn't seem to affect EOF. (If you
add an EOF test it will come out true.) But you could use #pos to get
back to the beginning of the stream.

Excellent, thank you.-Matthew Margolis
Why don't you just:
# complete:
content = File.read("blocklist.txt")
print content.include?("aa")
print content.include?("aa")
# line oriented:
content = File.readlines("blocklist.txt")
print content.include?("aa")
print content.include?("aa")
Much more efficient if the file fits into mem.
Kind regards
