Hey, guys.

I'm a new ruby learner. I'm so stuck on the regular expression part.
The following code is a fuction that passed in 2 strings: ftarget, which
is the location of a file to read; fkey is the key to match in the file.

The function simply does open the file, read each line and try to find
if there is a match fkey.

I tested the

i=0
          line.scan(fkey){|x|i=i+1}
          puts i
          if i> 0
            puts "Found match...\n\r"
          end



def fcmp(ftarget,fkey)
    @argc=ftarget
    puts fkey
    unless ftest(ftarget)
      puts "Invalid File name"
      return false
    end
    File.open(ftarget, 'r') do |f1|
        while line = f1.gets
          puts line
          i=0
          line.scan(fkey){|x|i=i+1}
          puts i
          if i> 0
            puts "Found match...\n\r"
          end
          #return false
        end
    end
  end
