Regular expression Manipulation in Ruby using gsub

Question

When I do "www.example.com/test/test".gsub('/test','') , I get "www.example.com" , but my desired result is "www.example.com/test" . That is, only the last "/test" should be removed. How do we achieve it?

Answer 1

Use "www.example.com/test/test".gsub(/\\/test$/,'')

UPDATE after comment

Event if it is working with gsub , sub seems more appropriate as you only want to replace one time :

"www.example.com/test/test".sub(/\\/test$/,'')

Answer 2

尝试这个

"www.example.com/test/test".sub('/test','')
