It scans directories for symbolic links and lists them on stdout, often revealing flaws in the filesys‐ tem tree. Each link is output with a classification of relative, absolute, dan‐ gling, messy, lengthy, or other_fs. relative links are those expressed as paths relative to the directory in which the links reside, usually independent of the mount point of the filesystem. absolute links are those given as an absolute path from the root di‐ rectory as indicated by a leading slash (/). dangling links are those for which the target of the link does not currently exist. This commonly occurs for absolute links when a filesystem is mounted at other than its customary mount point (such as when the normal root filesystem is mounted at /mnt after booting from alternative media). messy links are links which contain unnecessary slashes or dots in the path. These are cleaned up as well when -c is specified. lengthy links are links which use "../" more than necessary in the path (eg. /bin/vi -> ../bin/vim) These are only detected when -s is specified, and are only cleaned up when -c is also specified. other_fs are those links whose target currently resides on a differ‐ ent filesystem from where symlinks was run (most useful with -r ). ... Be careful of cleaning up messy links. If you run `symlinks -c` over /etc/systemd, the system probably will not boot. Or that's what happened in the past to me. I did not investigate why.
My main query with this was why do I get all those types of messages from symlinks when I issue "sudo symlinks -r -d /" which is the command to delete dangling symlinks?
