A botched terminal command left me without a
/usr/share folder. Most things seem to be running ok (although I haven't restarted since, so it's not clear if I'd have errors on reboot). There are already a few things wrong though, such as not being able to backspace in zshell, and emacs refusing to start up (giving me a
Cannot open terminfo database file message). I'm not sure what in all is stored there, so I don't know what if anything I can do to reinstall necessary files, etc. Alternatively, is there a repair utility built in to OS X that might be able to restore at least some of the most essential things?
Note: I unfortunately don't have any backup software installed. Live and learn.
