how to use sed to get 2nd range?

Hi all,

Is there a way to use the sed command to get the second range?

For instance:

sample.dat:
-------------

11111
22222

33333

44444

-------------

using "sed -n '/^ping/,/^$/p' sample.dat can get the first 2 lines.
But is there a way to get the first 4 lines, from beginning to the line with "3"?

Thanks in adv.

sed -n '1,4p' infile
3

Thanks for the answer.

But it is not the exact one i need, since in my case, the line number for first part, above the first blank line, maybe variable.

It would be great if there is a way to get the line from "1111" to the line above the second blank line, the line 5 in my sample.

You don't need to match the blank lines

sed -n '/^11111$/,/^33333$/p' infile

If this is not what you want, post your real data and desired output.
