lns is an old-school Perl utility that unbreaks the command order of ln -s.
If you’ve got a file called a.txt and you want to make a symbolic link b.txt, you can type lns a.txt b.txt or lns b.txt a.txt and it’ll do the intelligent thing. This is really handy. It won’t overwrite anything. It won’t break shit. It’s in my ~/bin/ forever now.
