Hi! I have a list of files with sequential naming. I've brought this file list into an array. I need to create a smaller arrays based on the filename structure--grouping like filenames... and then do 'something' to each array. To be clearer, here's an example:

@array = (001.file.a, 001.file.b, 002.file.a, 002.file.b)

I need to extract those files with matching prefixes (ie. 001) into a separate array, and do 'something'. When finished, extract those files with the next prefix (ie. 002) and then do 'something'... and on and on. I can't rely on the prefixes following sequentially (ie. 001, 004, 018), so I'll have to do some sort of compare of $array1 to $array[0] and then push if necessary i think...

I don't need help with the regex/grep portion, but moreso how to iterate through and extract matches, do 'something', then repeat with the next set of matches. Thanks in advance for any help! a:)
