Subject: removing newline from eachline in file

I'm reading a file line by line and trying to remove the newline at the
end of each line so that I can rebuild the url with the "www" and the
".net" at the beginning and end. Does anyone know how I can remove the
newline char at the end of each line? Also if the url doesn't work/exist
I don't want the script to crash I want to keep moving through the file
its reading.

begin
    while (line = f.readline)
        line = line  =~ /(.*?)\n/
        url = "www." + line + ".net"

        open(url) { |page| page_content = page.read()
    puts "link exists"
  }
    end
rescue
puts "link does not exist"

rescue EOFError
    f.close
end
