Subject: Help with one-liner

Hello,

I'm having problems with an one-liner (ruby 1.6.8 (2003-02-25) 
[i386-cygwin]).

My one liner sample:

$ ping localhost | ruby -e '$<.readlines.each { |line|  line.chomp!(); 
puts(line + "---\n");  }'

I would expect it to put --- at the end of each line. Instead it 
replaces the first 3 chars of each line with "---"

What am I doing wrong? And why? :)

Thanks.



Best regards.
