Could you please give some more details? I still do not understand
how gsub works...

irb(main):101:0* puts "aa\\bb".gsub(/\\/, "\\")
aa\bb
=> nil
irb(main):102:0> puts "aa\\bb".gsub(/\\/, "\\\\")
aa\bb
=> nil
irb(main):103:0> puts "aa\\bb".gsub(/\\/, "\\\\\\")
aa\\bb
=> nil
irb(main):104:0> puts "aa\\bb".gsub(/\\/, "\\\\\\\\")
aa\\bb
=> nil
irb(main):105:0> puts "aa\\bb".gsub(/\\/, "\\\\\\\\\\")
aa\\\bb
=> nil
irb(main):106:0> puts "aa\\bb".gsub(/\\/, "\\\\\\\\\\\\")
aa\\\bb
=> nil
irb(main):107:0> puts "aa\\bb".gsub(/\\/, "\\\\\\\\\\\\\\")
aa\\\\bb
=> nil
