Subject: [ruby-talk:28556] Re: help with ^M (line endings ) removing

Thank you very much for your emails.

I used following small script to remove ^M. Please let me know whether it can
be imporved in any way
====code start==========

#!/usr/bin/env ruby
if ARGV.length > 0
        name = ARGV[0]
else
        print "USAGE: remove_ms.rb filename"
end
def remove_ms(filename)
        puts filename
        fh = File.new(filename, "r")
        lines = fh.readlines
        fh .close
        fh = File.new(filename, "w")
        puts lines
        lines.each do |line|
                line.gsub!("\015", "")
                print "damn has ^M character #{line}"
                fh<<line
                end
        end
end
remove_ms(name)
=======code end========
Thank you.
