How to extract file name from path's for both windows and nix format?

Hi,

We have a data source containing File Path's from both Windows and Linux formats.  Applying regex separately works but how can I extract all file names regardless of format in a single search?

Following works for all Windows path's but for Linux, entire path gets extracted as file_name

 

| rex field=file_path "(?P<file_name>[^\\\]+)$"

 

 whereas this one works for Linux but does nothing on the Windows path.

 

 | rex field=file_path ".*\/(?<file_name>.*)$"

 

 

Is there a way to use both in same search? or a new regex that would work on either of the two formats?

 | rex field=file_path "(?<file_name>[^\/\\\]+\..+)$"

 

Negation for / and \, match everything that has at least one dot. Tested on:

C:\test\test.tst
/test/test/test.tst
/test/test/test.tst.tst

This regex works in my limited testing.

| rex field=file_path "(?<file_name>[^\/\\]+)$"
