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

Calibre/Item:  Shotgun Shell Holder
Make:  Red Quoll
Model:  DCPU
Condition:  New
Price:$50
http://Product.aspx?p=24584

Calibre/Item:  Reloading
Make:  Remington
Model:  357 cases and dies
Condition:  Excellent
Price:$320
State: NSW
http:///Product.aspx?p=24655

Calibre/Item:  30-06
Make:  Ruger
Model:  M77 Mk.II
Action:  Bolt repeater
Scope/Sights:  Zeiss 3-9x40
Condition:  Excellent
Price:$1200
http:///Product.aspx?p=24654

Calibre/Item:  222 Rem Mag
Make:  Sako
Model:  L461
Action:  Bolt repeater
Scope/Sights:  Sako rings
Condition:  Good
Price:$1500
State: QLD

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

Open in new window

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.

Excellent!
Works a charm. Just had to replace the double quote with a single quote after '/regex/'

THank you

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

Open in new window

ozo

for text in 'Custom1911' '$2800' 'Semi Auto' ; do perl -00 -ne 'BEGIN{$r=shift};print if /\Q$r\E/' "$text" $newContents >> outputfile.txt ; done

ozo

Sorry, I don't remember seeing an answer when I posted.
