Thanks for your suggestion. No, the resulting file may be different in file length. To be more specific, Consider the file contents as: A B C D E F G H and I want to replace the lines 2-4 which may result in a file being A X Y Z D E F G H the problem that I am facing is the time it takes to write out the line 5 to end of file in cases where the file size run into GBs. Is there a way I can cat the contents from D to H to the modified top portion?
