UNIX embedded command in sed problem.

I have a problem with trying to embed a command inside of a sed command. I wish to do something like this...
     sed '/cut -c29-36 < textfile/!d' infile outfile | sed...
The problem lies in getting a database name into the sed without piping it to it and without the text coming from the standard infile for sed. I have tried quotations, graves marks, etc. Have approached the SAs with the problem, but they are too busy, or don't know. Probly don't know. I would appreciate any input on this problem, including ways around it. A diff command will not work for me here due to the very similar names of the DBs. If you need more info on the problem, email me@ jpe719@aol.com

could you please explain more detailed what the first sed in the
pipe should do, and what the second.
Where in your listed command is the database name?

Also, some shells require escaping \! inside of ''

You mean you have a file that you can snip a name from with cut:
   TARGET=`cut -c29-36 < textfile`
then you want to delete lines from "infile" that contain that
target name:
   grep -v "$TARGET" <infile ...

Sed is a Great Tool  (I wrote a calculator in it).. but you do
not need it here.
