    Simon beat me to the answer.... That is what I get for eating lunch :o)

    That is exactly the issue. The field used for the join index must be sorted such as "sort -b"..... Not "sort -n".

    If you sort -b the two files first and put the output to two new files and then join them, you will see all 15 lines this time.

    Hope that helps,

    I think the problem is that join assumes alphabetic, not numeric sequence.
    So "10" is less than "9" and it gives up in disgust. The man page for join
    would suggest that you need to do a normal sort - just sort, or sort -b -
    before you do your join. If you need it in numeric order, do a sort -n on
    the result.
