$rsubstr(<substring> <search string>)
The <substring> argument is a dword which is unlike most other functions.
This function searches for <substring> from the end of <search string> and returns the $index() to it.
They can be used to search for specific things in output from a server, or as an alternative to $match(*substring* searchstring).
- -1 if <substring> not found in <search string>
- index to <substring> in <search string> if found
