A somewhat cleaner way of doing this is to use the ``comm''
command as it generates a straight list as opposed to diff which
requires parsing the output.
cd /dir1
find . | sort > /tmp/find.mirror1
cd /dir2
find . | sort > /tmp/find.mirror2
# This will give a list of lines in mirror2 not in mirror1
comm -13 /tmp/find.mirror1 /tmp/find.mirror2 > /tmp/missingfrom1
# This will give a list of files in mirror1 not in mirror2
comm -23 /tmp/find.mirror1 /tmp/find.mirror2 > /tmp/missingfrom2
