  • The symlinks command can show status of all symbolic links, including which links are dangling, which symlinks point to files on other file systems, which symlinks use ../ more than necessary, which symlinks are messy (e.g. having too many slashes or dots), etc. Other useful things it can do include removing all dangling links (-d) and converting absolute links to relative links (-c). The path given must be an absolute path (which is why I used $(pwd) in the example command).

  • Extremely useful to maintain backups if you're using Dropbox. This mirrors the entire directory structure and places symlinks in each to the original file. Instead of copying over the data again to the ~/Dropbox folder creating a symbolic link tree is much more sensible in terms of space usage. This has to be supplemented by another script that removes dead symlinks in the Dropbox folder which point to files that have been moved/removed. find -L ./ -type l -delete And then removing empty directories find ./ -type d -exec rmdir 2>/dev/null {} \; **Actually after some finding I found lndir which creates symbolic trees but it wasn't in the Arch repos so.. ;)
