How to print raw string in ruby?

Question

I want to print escaped or raw version of a string. For example: given this string:

"a,
b,
c,
d"

I want to get

"a,\nb,\nc,\nd".

Is it possible?

Your question is not clear, in part because it's only newlines that you escape in your example. Please define what you mean by "escaped or raw version of a string". Aside: when you give an example (which is generally most helpful), please assign a variable to each of your input objects (e.g., str = "a,...."). That way, readers can refer to those variables in answers and comments without having to define them. — Cary Swoveland

s = "a,
b,
c,
d"
s.dump
# => "\"a,\\nb,\\nc,\\nd\"" 
s.dump[1...-1]
# => "a,\\nb,\\nc,\\nd"

I think it's better to slice rather than delete if the string may contain "
