linux - Unlink (remove) directory symlink

I did:

ln -s /DATA/ ./base_DATA/

and I'd like to unlink. Simply:

unlink ./base_DATA

but... unlink: cannot unlink './base_DATA': Is a directory

According to this answer (and many other online) the problem is usually the trailing space in the unlink command. But I get this error regardless.

Any ideas how to tackle this?

Answer

./base_DATA/ is a normal directory that existed before. Your ln command created a symlink inside it. The symlink is ./base_DATA/DATA. You can unlink it:

unlink ./base_DATA/DATA
