HP-UX 11i v2. #!/bin/sh

Hi all.

I have a flat file like this with lines like this:

|07/19/07|08:26AM|1|CupsCoffee|CupsCo|989898989 |Doe, John Y |THE PLUS CARD - Price| | |Y| | 2.00|

I would like to replace the id number (field 6) with a masked version, ie *****8989. Everything else stays the same. The field is always 9 characters. I was thinking about sed or maybe tr.

Thanks in advance!!!!
