Recursive Grep between two words and print on matched word

Hi All,
I've tried this a few different ways however cant seem to work it out.

Given this input file : "$newContents"
Calibre/Item:  Shotgun Shell Holder
Make:  Red Quoll
Model:  Black
Condition:  New
Price:$50

Lets say I want to dispaly all the lines between "Calibre/Item" and "http" if  "9mm" is found.
I am using this, which works perfectly

awk '/Calibre\/Item:  9mm/,/http/'  $newContents >>  outputfile.txt


However, When I need to search for "Make" which is the second line in the block, I still need to display everything from "Calibre/Item" and "http". However I can't use awk (becuase I'm not searching for 9mm any more).
SO I've been doing this.

grep -i -B1 -A6 'STI'    $newContents >>  outputfile.txt

I'd like to have a generic grep/awk/sed whatever, where no matter which line in this block
I searched :

Calibre/Item:  9mm
Make:  STI
Model:  Custom 1911
Action:  Semi auto
Barrel Length:  152mm Holland Precision
Condition:  Excellent
Price:$2800
http:///Product.aspx?p=24652

It would always display the contents between "Calibre/Item" and "http"

I want to be able to match text on any line : "Custom1911", "$2800", "Semi Auto"

Etc.

Try this...
perl -ne 'BEGIN { $/ = "\n\n" } print if /regex/" inputfile > outputfile

Open in new window

Just replace /regex/ with what you want to search for (/Custom 1911/, /\$2800/, /Semi Auto/, etc).

THank you

perl -ne 'BEGIN { $/ = "\n\n" } print if /regex/' inputfile > outputfile
