I use the sort function to order an array of filenames alphabetically; for example:

@names = ( "FLY_ABC123_01.jpg", "PG_ABC123_03", "SPL_ABC123_02.jpg" );

The normal sort function can return the files in ascending alphabetical order, which would be: FLY_ABC123_01.jpg, PG_ABC123_03.jpg, SPL_ABC123_02.jpg.

However, I would like to sort these filenames based on the number after the last underscore (e.g. "_01"). Is there any way to do this?

I guess one option would be to ignore the characters before the first underscore (e.g. "FLY_").

Thanks,
Ralph
