When linking a directory to root, I get this error:
$ ln -s ~/inbox/ / $ ln: //: Is a directory
Bash autocompletes the directory path by adding a /. I've tried escaping without success.
$ ln -s ~/inbox /
works though. Why is this?

In pathname resolution, having a trailing
/ is equivalent to a trailing
/. — in other words,
~/inbox/ is equivalent to
~/inbox/. in this context. So the
ln command is trying to create a link called
. in the root directory (and, unsurprisingly, failing).
Zsh removes the trailing
/ when you press Space after completing a directory (unless configured not to do so). I don't know if bash can be made to do this.
Is that exactly what you ran?
Is a directory looks like your OS printing the
EISDIR error, which could happen two ways:
Trying to overwrite an existing symlink that points to a directory.
$ cd $(mktemp -d) $ mkdir dir $ ln -s dir dir # this creates dir/dir $ ln -s dir dir # this fails, because dir/dir already exists ln: failed to create symbolic link `dir/dir': File exists
Trying to create a hard link to a directory.
$ cd $(mktemp -d) $ mkdir dir $ ln dir dirlink ln: `dir': hard link not allowed for directory
If it is what you were running, what does
type ln or
alias ln print?
