How do I escape #{ from string interpolation

If I have a string like this:

"interpolated: #{1}, verbatim: #{dont_interpolate}"

How do I escape only the second #{} such that the output looks like this:

=> interpolated: 1, verbatim: #{dont_interpolate}

I tried this:

 "interpolated: #{1}, verbatim: #\{dont_interpolate\}"

but I get an extra slash in front of the #:

interpolated: 1, verbatim: \#{dont_interpolate}

No problem, I wasn't quite sure if it would apply, because the solution was related to irb. — Tim, Jan 26 '13 at 02:41

I think this is just pretty-printing the string in irb. When I use puts, it prints correctly:

irb(main):002:0> "interpolated: #{1}, verbatim: #\{dont_interpolate\}".to_s
=> "interpolated: 1, verbatim: \#{dont_interpolate}"
irb(main):003:0> puts "interpolated: #{1}, verbatim: #\{dont_interpolate\}"
interpolated: 1, verbatim: #{dont_interpolate}
=> nil

It seems you can also escape it this way:

irb(main):004:0> puts "interpolated: #{1}, verbatim: \#{dont_interpolate}"
interpolated: 1, verbatim: #{dont_interpolate}
=> nil
