Comment on Grep flags – the good stuffparentComments−VTimofeenko4yThe way I remember this is by keeping in mind that grep processes the area of the search as a stream of discrete lines by looking at each line individually. "Above/below" are concepts on the stream level, and "after/before" are on the line level.
