something like

chmod `grep 1020 /etc/passwd | awk -F: '{print $1;}'` \
  `find . -uid 1010`

or to make it reusable

!!!WARNING!!! this is not tested or debugged.  I just wrote it.

#!/bin/sh

USER1=$1
USER2=$2
MYPATH=$3

usage()
{
  echo "Script to change ownership of files from user X to user Y"
  echo "$0 <user1> <user2> [path to search]"
  echo
}

if [ -z "$USER1" ] ; then echo "Invalid user 1"; usage ; exit 1; fi
if [ -z "$USER2" ] ; then echo "Invalid user 2"; usage ; exit 1; fi
if [ -z "$MYPATH" ] ; then MYPATH="./" ; exit 1; fi

UID1=`grep $USER1 /etc/passwd | awk -F: '{print $3;}' `
UID2=`grep $USER2 /etc/passwd | awk -F: '{print $3;}' `

if [ -z "$UID1" ] ; then echo "Invalid user 1"; usage ; exit 1; fi
if [ -z "$UID2" ] ; then echo "Invalid user 2"; usage ; exit 1; fi

chmod `grep $USER1 /etc/passwd | awk -F: '{print $1;}'` \
  `find $MYPATH -uid $UID2`
