Copy ranges of lines from standard input to standard output.
rng range ...
rng copies the specified line ranges from standard input to standard output. Ranges can be specified as follows:
|from:to||Line from through to (inclusive).|
|from:||Line from to end of input.|
|:to||Start of input to line end (inclusive).|
|:||The entire input.|
|line||Line line only.|
Line numbers go up from 1 relative to the start of input, and down from -1 relative to the end of input.
Use of negative line numbers, overlapping ranges, or backtracking ranges causes the file to be buffered in its entirety.
Output lines 2-5 of a file:
rng 2:5 <file.txt
Output the first three, fifth, and last three lines of a file:
rng :3 5 -3: <file.txt
