sed 's/\"//g' n2p.temp1 > n2p.temp2


perl -lne "print if/BP-COLLECTOR$/../;/" n2p.temp2 >n2p.temp3
sed 's/\;//g' n2p.temp3 > n2p.temp4
sed 's/\ //g' n2p.temp4 > n2p.temp5

sed 1d n2p.temp5 > n2p.temp6

rm -f n2p.temp1
rm -f n2p.temp2
rm -f n2p.temp3
rm -f n2p.temp4
rm -f n2p.temp5

First off: You can do all that in a single sed and forego the whole script as well as the half dozen temporary files:

Code:
sed -n '/CONNECTIONS$/,/DEVICES/ {
             s/"//g
             /BP-COLLECTOR$/,/;/ {
                  s/ //g
                  s/;.*$//p
             }
}' /your/input/file

Test this first if it gives you the correct answer in every case. If you are satisfied with the outcome of this you can put it into loop, like this, which solves your second problem:

Code:
while read LINE ; do
     sed -n '/CONNECTIONS$/,/DEVICES/ {
                  s/"//g
                  /'"$LINE"'$/,/;/ {
                       s/ //g
                       s/;.*$//p
                  }
     }' /your/input/file
done < /your/file/with/search-words

I hope this helps.

LEARN ABOUT DEBIAN

newbiedoc

NEWBIEDOC(1)						      General Commands Manual						      NEWBIEDOC(1)

NAME

       newbiedoc - Debian documentation for newbies by newbies.

SYNOPSIS

       newbiedoc
       newbiedoc file

DESCRIPTION

       This  manual  page  documents  briefly the newbiedoc command. The program newbiedoc is a small script that starts your favorite browser and
       displays the index page of the NewbieDOC documentation package. Optionally, you can specify the name of a specific  file  to  open  in  the
       browser.

       newbiedoc can also be run directly from the Debian menu in the X Window System: Debian -> Help -> NewbieDOC.

       NewbieDOC  documentation  is  in  the form of HTML files which form a snapshot of the documentation currently being developed by the Debian
       NewbieDOC project. Visit the wiki at http://newbiedoc.berlios.de for the most recent versions, or if you wish to contribute to the project.
       The wiki is very easy to use. All Debian users are encouraged to author, edit or add comments to the articles.

       Each NewbieDOC item is either explicitly licensed by its author, or licensed globally under the GNU Free Documentation License.

SEE ALSO

       The NewbieDOC wiki is at http://newbiedoc.berlios.de

AUTHOR

       The upstream source for newbiedoc was written by Chris Lale <chrislale@untrammelled.co.uk>.

       This manual page was written by Chris Lale <chrislale@untrammelled.co.uk>, for the Debian project (but may be used by others).
