if that wont work.......?
If awk cant do this directly, does it make and sense to first take the part number which is the first 15 characters and dump it to a temp file, then run uniq on it. afterwards do something like:
#filter_sum.awk
/PARTNUM/ { sum+=$2}
END { print sum }
except instead of /PARTNUM/ so some sort of
for x in `cat sum.awk.tempfile`;do gawk '{ /$x/ { sum+=$2} END { print sum }'
i havent gotten it to work yet but need some opinions on whether this is the right way..

The options are as follows:
-c Output is formatted for a display columns wide.
-s Specify a set of characters to be used to delimit columns for the -t option.
-t Determine the number of columns the input contains and create a table. Columns are delimited with whitespace, by default, or with
the characters supplied using the -s option. Useful for pretty-printing displays.
-x Fill columns before filling rows.
column exits 0 on success, >0 if an error occurred.
ENVIRONMENT
COLUMNS The environment variable COLUMNS is used to determine the size of the screen if no other information is available.
EXAMPLES
(echo "PERM LINKS OWNER GROUP SIZE MONTH DAY HH:MM/YEAR NAME";
ls -l | sed 1d) | column -t
