Yes. Keeps getting 1024 byte chunks until EOL as per the documentation.

Ignore comment lines (#)
Yes, explode the entire file in to one line per array key.

Take each line/key of the array and split it into another array of 'stuff'
Ignore any spaces between chunks of data. If you look at the data file,

It helps with blank space between MAC, image and name columns on a single
line.

Yeah, in my case, I only count a # at the beginning of a line AKA $line{0}
