Hmmm.. I did say there was plenty of room for improvement, after all,
obviously shell scripting is more prone to failure than a proper program
in C but let's give it a shot:
----------------------------------------------------------
#!/bin/bash
set -e
DIR_TO_FIX=/home/groupX
GROUP=mygroup
PERM=g+rwX
VALIDUSERS="me|myself|other"
find $DIR_TO_FIX -type f -printf "%u %p\n" |
egrep "^$VALIDUSERS " |
while read user file
do
# Recheck the user and file, avoid races
[ -e "$file" ] && {
curuser=`ls -dl "$file" | awk '{ print $3 }'`
[ "$curuser" = "$user" ] && {
chown $GROUP "$file"
chmod $PERM "$file"
}
}
done
---------------------------------------------------------

As an enhancement over the -h option? (to exclude hard links as
well as symlinks)
