How do I insert backslash?

I have string like file name. I want to output like file\ name. I have tried following.

ruby-1.9.2-p290 :060 > s.gsub(/\s/,"\ ")  
 => "file name"   
ruby-1.9.2-p290 :074 > s.gsub(" ","\\")  
 => "file\\name"

Any help would be great.

You can also use 'single quoted strings'. They are not escaped in ruby.

You probably want

s.gsub(" ","\\ ")
=> "file\\ name"

This is a single backslash character, but its representation needs a double backslash to differentiate it from an actual escape sequence like \n.
