Re: [FishMonger] Dynamic Logging of any File used in Script

If a script opens several different files:
open( $FH_1, '>', $file_name_1 );
open( $FH_2, '>', $file_name_2 );
open( $FH_3, '>', $file_name_3 );
What would be the easiest way for me to know the name of the files opened by the script?
If the script used only one filehandle, $FH, then I could simply watch this variable for any changes, and update the log accordingly. In the real world, however, there is no guarantee some one will use only a single filehandle variable.
The main point is that I want this script to "plug" into any existing Perl script without needing to modify either script too much; therefore, I'm essential ignorant of the actual name of the variables used. I would have to realize on a either a global variable, or generic data type that all filehandles fall under.
Perl Hierarchy:

<Generic Filehandle> <--Does this exist?
