I need to do a .gsub or .split or the equivalent to locate  
carriage-return  
characters ­ Hex 0d . How can I do this in ruby? Thanks. Bill W.

irb → puts “hello\x0d”.gsub(/\x0d/, ‘!’)  
hello!

CR is represented as “\r”

0x0d.chr  
#=\> “\r”

so,

“test\rx”.gsub(/\r/){“[]”}  
#=\> “test[]x”

“test\rx asdfa\rasdf”.split(/\r/)  
#=\> [“test”, “x asdfa”, “asdf”]
