$funcfiletrace  –  Absolute Line Number and File Name of the Current Call

$funcfiletrace contains the absolute line numbers and file names of the current call location. It’s available for functions, sourced files and eval commands (if EVAL_LINENO is set).

The alternative $funcsourcetrace contains relative line numbers, which makes it less useful for most use cases.
