Ok, this has me banging my head. In OS X, to create a hard link, in a terminal window, you're supposed to be able to just type this...
ln a.txt b.txt
...and this should create a hard link from
b.txt. Simple and straight forward.
When I execute that statement, sure enough, in Finder
b.txt appears right alongside
a.txt. However, even after editing
a.txt using TextEdit,
b.txt still has the original data! In other words, it looks like it performed a copy, not a link, hard or otherwise.
Makes no damn sense to me! So can someone tell me what I'm doing wrong here?
