Ok. Now that's awesome. Multi-line record handling. Very smart. I also had no idea that setting RS to null would separate records at blank lines. Very cool. I put those blank lines in so it would look pleasing if I had to manually modify it. Guess I got lucky Smilie

I modified it to make sure it only matches that string if it's a defined "host_name":
Code:
awk '!/host_name\tXMPP_ec2-184-1-1-1/' RS= ORS="\n\n" infile

and it works perfectly.

Thanks!!

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
