One of my work colleagues asked me a few weeks ago what it took to make /etc show up in the Finder on the Macintosh.
I knew it was some kind of HFS+ invisibility setting — but I honestly had no clue how to change that setting. About the only thing I knew to say was suggest doing a “open /etc” from a terminal window.
For reasons I don’t completely I can’t seem to get it to work on /etc (which is a symlink to /private/etc in OS X — and /private/etc is already technically visible and the ‘v’ visibility parameter is only a folder attribute according to the SetFile man page) — but I can get a:
/Developer/Tools/SetFile -a v private
to work, executed in a sudo’d shell. And then at some seemingly random point (facilitated perhaps by removing /.DS_Store) the Finder realizes it can see /private
For the record GetFileInfo shows the HFS+ attributes.
(obviously the developer tools should be installed, which you should be doing by default if you are reading this blog and own a Macintosh)
