usage: grep [-E|-F] [-c|-l|-q] [-bhinsvx] -e pattern_list...
        [-f pattern_file...] [file...]

        -f pattern_file... [file...]
usage: grep [-E|-F] [-c|-l|-q] [-bhinsvx] pattern [file...]

please help me to over come this issue. Thanks!

Something like this?

awk '/Good/{c=5;next}c && c-- > 0' file
3

or may be sed...

sed -n '/Good/{g;N;N;N;N;N
p
}' filename
4

just a little modification to Franklin code:

awk '/Good/{c=4;next} c-->0 ' file1.txt

Thanks to Franklin

regards,
Sanjay

If you are using GNU sed,

$sed -n '/Good/,+5p' filename
Good
