Subject: Re: Searching in a directory

First of all thank you very much for help. I want to search in all .txt 
files of a folder for a string and when I find this string, then i call 
a function_1. If there's no string, I call a function_2. Later the 
string will be dynamic, but that's not important now. I took the code 
from Josh and tried a bit, but there's still a mistake concerning 
reading the whole file.

Dir["**/*.txt"].each do |filename|
  if
    File.readlines(filename).include?("123"+"string") then
    puts("function_1")
  else
    puts("function_2")
  end
end
