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.

nwbpset

NWBPSET(1)							      nwbpset								NWBPSET(1)

NAME

       nwbpset - Create a bindery property or set its value

SYNOPSIS

       nwbpset [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ]

DESCRIPTION

       nwbpset Reads a property specification from the standard input and creates and sets the corresponding property. The format is determined by
       the output of 'nwbpvalues -c'. nwbpset will hopefully become an important part of the bindery management suite of ncpfs, together with

       As another example, look at the following command line:

	 nwbpvalues -t 1 -o supervisor -p user_defaults -c |
	 sed '2s/.*/ME/'|
	 sed '3s/.*/LOGIN_CONTROL/'|
	 nwbpset

       With this command, the property user_defaults of the user object 'supervisor' is copied into the property login_control of the user  object
       'me'.

	 nwbpvalues -t 1 -o me -p login_control -c |
	 sed '9s/.*/ff/'|
	 nwbpset

       This command disables the user object me.

       Feel free to contribute other examples!

       nwbpset looks up the file $HOME/.nwclient to find a file server, a user name and possibly a password. See nwclient(5) for more information.
       Please note that the access permissions of $HOME/.nwclient MUST be 600 for security reasons.

OPTIONS

       -h
	  -h is used to print out a short help text.

       -S server
	  server is the name of the server you want to use.

       -U user
	  user is the user name to use for login.

       -P password
	  password is the password to use for login. If neither -n nor -P are given, and the user has no open connection to  the  server,  nwbpset
	  prompts for a password.

       -n
	  -n should be given if no password is required for the login.

       -C
	  By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off
	  this conversion by -C.
