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.

Hi All,
Is it possible to count number of occurrences of a pattern in a single record using awk??

zgrep
ZGREP(1) BSD General Commands Manual ZGREP(1)NAME
zgrep, zegrep, zfgrep -- print lines matching a pattern in gzip-compressed files
SYNOPSIS
zgrep [grep-flags] [--] pattern [files ...]
zegrep [grep-flags] [--] pattern [file ...]
zfgrep [grep-flags] [--] pattern [file ...]
DESCRIPTION
zgrep runs grep(1) on files or stdin, if no files argument is given, after decompressing them with zcat(1).
The grep-flags and pattern arguments are passed on to grep(1). If an -e flag is found in the grep-flags, zgrep will not look for a pattern
argument.
zegrep calls egrep(1), while zfgrep calls fgrep(1).
EXIT STATUS
In case of missing arguments or missing pattern, 1 will be returned, otherwise 0.
