Squence number manipulation in Shell

Hello Forum,

I am receiving a file daily like ASAD but at the end there is a counter like 0012 (4 digits) so my every next file +1
I want to write a control script and check the last sequence number.Let's say If I receive a file ASAD0012 then after receiving this file I wan to say that next seq_number is "0013"

How can manipulate this logic?

Thx AllSmilie
