The [question](http://superuser.com/questions/52483) was deleted on 2010-11-24 by [Diago](http://superuser.com/users/3981/diago)♦. It had [previously](http://superuser.com/posts/52483/revisions) been [locked](http://meta.stackexchange.com/questions/22228/what-is-a-locked-post) (i.e., basically, made read-only — locking has nothing to do with closing) since 2010-08-05. (Only ♦moderators and ≥10k-rep users can see deleted questions.) I have no idea *why* the question was deleted. It can still be undeleted by a ♦moderator.

For the time being, the content is still available via the [Google cache](http://webcache.googleusercontent.com/search?q=cache:tkkEtimeTdsJ:superuser.com/questions/52483/terminal-tips-and-tricks-for-mac-os-x). When it goes, it will undoubtedly live on on one of the many sites that mirror SU (finally a use for them!). The question is in the [data dumps](http://blog.stackoverflow.com/category/cc-wiki-dump/) produced before it was deleted.
