Hi

I find the syntax too vague. What are the section delimiters ? Or the sections have fixed length ? The keywords are fixed, or variable ?

Hi feherke

Sections are delimited by a BLANK LINE.

Keywords are fixed.

Thanks

Hi

Still not too clear. As I understand your question, the answer should be something like this :

sed -n '/Keyword/,/^$/p' inputfile > outputfile
[gray]# or[/gray]
awk '/Keyword/,/^$/' inputfile > outputfile

But you already know this from thread80-1135120 of forum80.

Hi Feherke,

The Keywords are fixed but different. Hence Keyword A and Keywork B.

Basically I want to grab the lines that contain Keyword A and follow with the range of lines starting with #Keyword B to the BLANK LINE.

Hope this helps.

Thanks

Perhaps this ?
awk '
/Keyword A/{print;next}
/Keyword B/,NF==0
' /path/to/input > output

Hope This Helps, PH.
