range, or many ranges separated by commas. Selected input is written
in the same order that it is read, and is written exactly once. Each
range is one of:
N N’th byte, character or field, counted from 1
N- from N’th byte, character or field, to end of line
N-M from N’th to M’th (included) byte, character or field
-M from first to M’th (included) byte, character or field
With no FILE, or when FILE is -, read standard input.
