thanks Bj�rn , expected result for digits, but I forgot any other 
characters , replacing the item after the last / was my goal

irb(main):007:0> str = "/proposals/list/31555"
=> "/proposals/list/31555"
irb(main):012:0> str.gsub! /[0-9]+$/, "9999"
=> "/proposals/list/9999"

but

irb(main):013:0> str2 = "/proposals/list/abcde"
=> "/proposals/list/abcde"
irb(main):014:0> str2.gsub! /[0-9]+$/, "9999"
=> nil


josss :-))
