Reverse cut...

Hi, I have a question on the command "cut":

-For example immagine that I want to select the filename from an absulute 
path (and the files hasn't all the same depth).

How I can ask to cut to start to count the delimiter '/' from the end of 
the string instead of from the start?

There are other solution?

Thank you very much and Best Regards!

Fabrizio.
