Using sed or similar how would you extract lines from a file? If I wanted lines 1,5,1010,20503 from a file, how would I get these 4 lines?
What if I have a fairly large number of lines I need to extract? If I had a file with 100 lines, each representing a line number that I wanted to extract from another file, how would I do that?
