sed search/replace and display
Hi All: I'm using sed to replace one line in a configuration file. After replacing that line I would like to display to screen that line plus 10 lines above and below the line that was changed... How would I go about doing that??
Here is my search and replace string....

sed -e "s/ipaddress.info=$IPchange/comm.info=$IPnew/" node.cfg >tmpnode2

What that line does is find the line ipaddress.info and replace the old IP ($IPchange) with the new IP address ($IPnew). So after the switch I'd like to display that whole section where the change was made which is about 10 line above and below the line that was changed....

Is that clear enough ??

Thanks again.. !!

SYNOPSIS

       comm [OPTION]... FILE1 FILE2

DESCRIPTION

       Compare sorted files FILE1 and FILE2 line by line.

       With  no  options,  produce three-column output.  Column one contains lines unique to FILE1, column two contains lines unique to FILE2, and
       column three contains lines common to both files.

       -2     suppress column 2 (lines unique to FILE2)

       -3     suppress column 3 (lines that appear in both files)

       --check-order
	      check that the input is correctly sorted, even if all input lines are pairable

       --nocheck-order
	      do not check that the input is correctly sorted

       --output-delimiter=STR
	      separate columns with STR
