Obviously, if each of these definitions is inclusive of exactly one file, a rote mv may be … Read more

I would harness GNU AWK for this task following way, let file.txt content be 9003103 9003103 9003978 9003979 9003763 9003728 9003543 9003543 9003543 then awk ‘BEGIN{RS=””}{diff=$NF-$1;diff=diff>0?diff:-diff}diff>NF’ file.txt gives output 9003763 9003728 Explanation: I set RS to empty string to provoke paragraph mode, thus every block is treated as single line, then for each block I … Read more
