Well I have it working more or less, thanks to everyone for the help. This is the script at the moment, warning, there should be an ugly flag on this somewhere.

A friend of mine said you should never be too embarrassed about something that actually works, but I am not so sure about this one.

After several attempts to put the script in code tags, I have attached it. The zip contains the script, the output from the first bin called by the script, and the output from the second bin, in case anyone wants to hot wire this and view the ugliness. It also contains the two output files, which are formatted as needed.

I am interested in learning, so any comments as to better methods of getting from here to there would be appreciated.

Thanks again, Image

And just for the heck of it, a sh solution (red underscore is one tab):

Code:
#!/bin/sh

file="$1"

i=0
IFS='____'
while IFS='' read -r line; do
    set -- $line
    if [ $i -gt 0 ]; then
        a=$i b=$i
    else
        a=index b=ID
    fi
    printf '%s\t%s\t%s\t%s\t%s\t%s\t%s\t%s\n' $a $1 $b $2 $3 $4 $5 $6
    : $((++i))
done < "$file"

Regards,
Alister

Try
Code:
awk '$1=(NR-1)?NR-1OFS$1OFS NR-1OFS:"index"OFS$1OFS"ID"OFS' OFS="\t" infile
