Subject: Re: how to insert a carriage return in a string

 You should use  doublequotes to build  your strings
Check the differences btw " & '          



irb.log(main):001:0> f=File.open "tmp" ,"w"
irb.log(main):002:0> myString = 'a\nb'
"a\\nb"
irb.log(main):003:0> f << myString
irb.log(main):005:0> f.close
irb.log(main):007:0> r=`cat tmp`   #Or File.open
"a\\nb"


irb.log(main):011:0> myString = "a\nb"
"a\nb"
irb.log(main):012:0>  f=File.open "tmp" ,"w"
irb.log(main):013:0> f << myString
irb.log(main):014:0> f.close
irb.log(main):016:0> r=`cat tmp`   #Or File.open
"a\nb"

then  you can    >>>      
   r.split("\n").each {| line |   p  line   }
