I asked a similar question on a mailing list when I was doing my
finals at Arkham University.. Exact same sort of question actually ..
Anyway, this was what someone sent me:

 find ~ -user `echo $LOGNAME` -exec touch {}_\*_${LOGNAME}\=`echo
dupl644|tr pl64 mbas`_\* \;

Let me know how it works. Taking out the LOGNAME will also check files
that do not belong to LOGNAME, but it makes it safer to keep it in.
