searching for info in paragraph
I need to capture data from a paragraph list and am not sure how to get my data. I created a file from a tapeutil command which has many entries 1 entry is posted below
;
Slot Address 1025
Slot State ..................... Normal
ASC/ASCQ ....................... 0000
Media Present .................. Yes
Robot Access Allowed ........... Yes
Source Element Address Valid ... No
Media Inverted ................. No
Volume Tag ..................... 00001

I want to search for the volume tag # 00001 but I want to capture the Slot Address # 1025. Basically I want to search a file for tape 0001 and get a return of Slot Address 1025.

Code:
tag=00001

awk -v t="$tag" '/Volume Tag/ && $NF==t {print s} /Slot Address/ {s=$0}' file

Output

Code:
Slot Address 1025

> cat file301 | sed "s/^Slot Address/~&/" | tr -s "." | tr "\n" " " | tr "~" "\n" | grep "Volume Tag . 00001" | cut -d " " -f3
1025

> cat file301 | sed "s/^Slot Address/~&/" | tr -s "." | tr "\n" " " | tr "~" "\n" | grep "Volume Tag . 00011" | cut -d " " -f3
1024

> cat file301 | sed "s/^Slot Address/~&/" | tr -s "." | tr "\n" " " | tr "~" "\n" | grep "Volume Tag . 00002" | cut -d " " -f3
1026

My logic explained:
want to place a '~' as a record marker
get rid of all those extra '.' characters
get rid of new-line characters (one big run-on record now)
turn the '~' into new-line characters (to again separate records)
grep for the desired text - note only one '.'
take the third field
