Shamrock,
I was wondering if you would be able to break that awk command apart with comments if you wouldn't mind? I'm trying to understand what the purpose of {f=1} & {f=0} are.
This looks like something I may be able to use at some point but I apologize, I don't understand what parts of it are doing
awk scripts are made up of pattern/action pairs which are executed on every line that awk reads.
/pairwiseDifferenceMatrix/ tells awk that whenever it sees that pattern on a line the action should be to enable a flag variable f...set f to 1...so this is kind of like saying START.
/^<\/pairwiseDifferenceMatrix/ tells awk that whenever it sees that pattern on a line the action should be to disable the flag variable f...set it to zero...so this is kind of like saying STOP.
f && NF==3 tells awk that if "f" is non-zero and NF (number of fields) equals 3...it should print the 2nd field of the current line...followed by getting the next line and printing its third field.
I'm trying to compare the first column values in two different files that use a numerical value as the key and output the more meaningful value found in the second column of file1 in front of the matching line(s) in file2. My problem is that file2 has multiple records. For example given:

I'm trying to use Awk to get the id and name fields ($1 and $2) of file1 combined with their corresponding multiline records in file2 that are separated by blank line. Both files are ordered so that the first line of file1 corresponds to the first set of multiline records in file2 and so on.

IGAWK(1) Utility Commands IGAWK(1)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
