Hi, Ive problems with comparing two files (line by line), which either have a different value in one of the column or the whole line is missing. File 1: # KB0001 21 K UWXKKSJ 0.3666 # KB0001 22 K UWXKKSJ 0.4666 # KB0001 23 K UWXKKSJ 0.5666 # KB0001 24 K UWXKKSJ 0.6266 # KB0001 25 K UWXKKSJ 0.7666 # KB0001 26 K UWXKKSJ 0.8666 # KB0001 27 K UWXKKSJ 0.9666 File2: # KB0002 21 K UWXKKSJ 0.3666 # KB0002 22 K UWXKKSJ 0.4666 # KB0002 23 K UWXKKSJ 0.5666 # KB0002 24 K UWXKKSJ 0.6666 # KB0002 25 K UWXKKSJ 0.7666 # KB0002 26 K UWXKKSJ 0.8666 In the output i want to print lines which are not in one of the files or ones that value is different Can anybody help me on this one?
