Here the numbers and the strings might change
This is very vague. Please specify the criteria by which certain lines would be selected and others would not..

Okay.. let me be clear with question.

i have below lines.

Code:
 1 1982        1          testing            init.cc  3001     Apr 25 2014    09:56:20.083
Start FH Log:
End FH Log.
 0 2014        1          testing            log.cc  3001     Apr 25 2014    07:55:10.032
logging for testing purpose:

Now i need to write regular expression for the line

Code:
 1 1982        1          testing            init.cc  3001     Apr 25 2014    09:56:20.083

such that i get the output
Code:
 1 1982        1          testing            init.cc  3001     Apr 25 2014    09:56:20.083
Start FH Log:
End FH Log.
 0 2014        1          testing            log.cc  3001     Apr 25 2014    07:55:10.032
logging for testing purpose:

It may appear that i need to print all the lines but that is not the case. I need the first section in one go and next section in another go. Hope i have clarified the question.
See that the lines 1 and 4 are different we cannot use the same number and strings.

So, you want to print all lines in the order they came in without modifying them any way, but can't use cat ? What constitutes a 'go'? You want to run the program once to get the first 3 lines, then again to get the second two lines...?

Do the columns mean anything? Explaining what the columns are would help. Right now we have no idea how much they're going to change.

What exactly are you trying to do? Tell us that, not the way you think you need to solve it...

" 1 1982 1 testing init.cc 3001 Apr 25 2014 09:56:20.083"
The numbers and the strings may change.

Let me get the answer for this. i will post my further question again.
