As you remember from previous Perl one-liners, -a is splitting each line into @F array, using space as default delimiter. To specify other delimiter we use -F option with regular expression following it (as with split function). If we use empty regular expression: //, each line will be split into separate characters, so each of the line's characters will be contained in separate @F field.

you can add
Code:
[[ -z $a ]] && continue

just after the "do" line so that empty lines will not be a problem
