Thanks Franklin!
I tested the second one. It works fine.
But i don't want to create another file. I tested the script as below
filename > filename. After executing the script, the <filename> becomes empty.
so isn't possible to remove the header & footer and store it in the same file itself?
Also can you tell me what is the difference between the first one and second one? i mean which will give give good performance?
