Question

This number is in a filename string eg. abcdefg-sdasdfg-123410.txt
I am using an application which is changing the filename and can use regex.
If there is a number at the end of the filename, such as 123410, I need to change the last 2 digits so it will be 123411.

Depending on which regex variant you’re using, try something like this:

Search for: (.*)10(\..*)
Replace with: ${1}11${2}
