As I mentioned you the file is pretty big and I am trying to update the source file at the same time too. I did some search and understand that sed buffer option can handle it but frankly could not understand.
Thanks

You never answered Scott's main question.
Is this a homework assignment? If this is not homework, why are we restricted to "
useing(sic)
awk for(sic)
sed"?
And, until now, you never said anything about wanting to update the file. You said you wanted to hash certain lines and did not want to hast(?) other lines. If you want to update certain strings in your file, what replacement text do you want to use? And, why do you care about "hash"ing lines you don't want to change?
How is your script supposed to determine which strings are to be replaced and what replacement text is to be used? Do you intend to hard code values into your script and edit your script every time before you run it? Will you be passing in pairs of command-line arguments specifying old and new text? Will you supply an input file that specifies old and new values? (If so, what will be used as the separator between old and new values in that file? And, what will be the name of that file (or will the name of that file be given as an operand)?)
What shell are you using?
What operating system are you using?
