How to strictly grep (with before and after args) for last N number of occurrences?
Here is my grep string to print only the last occurrence, with before and after lines. Note that the tail Argument is sum of B and A args + 1, so that it prints the data of only the last 1 match. Now I need to print last 2 such matches. I thought of doubling the tail arg like 5+5+1 (For -- line), for ex: tail -11 should return last 2 matches, but I want it to be strict (I guess its tail -maxNumber, but I want it to be something like tail -MinNumber), so it has to either print 2 occurrences or nothing. Right now even if there is only one sample, it returns the output, I want output only if there are at least 2 matches. May be we can pipe it to awk to solve this. Please help.

| | This handler now adds the charset HTTP header |

| | |
| | o Content-Type has not been set, |
| | using header(3). |
| | |
| | o The default MIME type begins with |

EXAMPLES
Example #1
mb_output_handler(3) example
<?php
mb_http_output("UTF-8");
ob_start("mb_output_handler");
?>
NOTES
Note
If you want to output binary data, such as an image, using PHP 4.3.0 or later, a Content-Type: header must be set using header(3)
before any binary data is sent to the client (e.g. header("Content-Type: image/png")). If Content-Type: header is sent, output char-
acter encoding conversion will not be performed.
Note that if 'Content-Type: text/*' is sent, the content body is regarded as text; conversion will take place.
If you want to output binary data, such as an image, using PHP 4.2.x or earlier, you must set output encoding to "pass" using
mb_http_output(3).
