Search for last character of the same kind in a string

[pancakegh]

Hi,

Is there a way to find the position of the last character of the same kind in a string?

for example:

I want to rename my files to "387.20.1082.jpg"
the files are all named: "nike-kaishi-grijze-lage-kinder-sneakers-24139-387.20.1082.jpg"

The text part is always different and the number of " - " symbols are always different too, depending on the names.

I know I can search for the " - " substring, but how do I find the position of the last " - " character so I can delete the piece of string up until that position? So the "387.20.1082.jpg" part remains as a result?

See below two examples

Example 1 uses Strings actions

Example 2 uses regular expressions.
It is more simple but you have to be familiar with the syntax of regular expressions, of course.

Save the text of the tasks to a files and use menu Task->Import to import the task into RoboTask.
