What Others Think

This does not actually count occurrences of the pattern [space][new line][space][new line], but counts the [space][new line] quantity and then halves it. It's useful if there are no single [space][new line] occurrences, but the following example would return 1. [space][newline] test [space][newline] Not sure how to do that using grep, since grep works per line. Maybe use awk.
