I recently hacked together a little script to check for stale symbolic
links:
#!/bin/sh
#
# Check symbolic links to make sure they're valid pointers
if [ $# -eq 0 ]
then
root=/
else
root="$(realpath $1)"
fi
IFS=$(echo -e "\n")
find "$root" -type l | while read link
do
echo -n Checking "$link..."
lp="$(readlink "$link")"
if [ ! -e "$lp" ] && [ ! -e "$(dirname "$link")/$lp" ]
then
echo Bad link: "$link" -- "$lp" does not exist
else
echo OK
fi
done
