There are a couple of ways to do that:

[1] pry(main)> puts "xyz#abc".gsub("#","\\\\043");
xyz\043abc
[2] pry(main)> puts "xyz#abc".gsub("#") { '\\043' };
xyz\043abc

There's an explanation of how the replacement string is double interpolated at http://www.ruby-forum.com/topic/143645

Hope this helps,

Mike
