Is there a way to find the last occurrence in a string of a character?

For instance, if I want to get the file part of a file path (/a/b/c/file.txt), how can I extract that?

I assume you don't want to do this via regex but in a transform stage, correct? The following derivation will give you the last substring delimited by a '/'.

Just to confirm, you specifically mean the last 'occurance' in a delimited string, yes? That was your 'for instance', just wanted to make sure that would cover all of the bases.

You can use the UNIX command basename for this particular task (getting the file name from a pathname).
