There is also another way. You might want to check out this port called symlinks (/usr/ports/sysutils/symlinks). It can check out links as simple as: symlinks -r / | grep ^dangling It can change absolute/messy links to relative, delete dangling links, recurse into subdirs and shorten lengthy links. :-) All in one!
