title: Why can't I (or how can I) save the output of brew doctor with pipes?
body: <p>I'm not sure just how specific this is, but when I run 'brew doctor' I see some error messages. If I want to save those messages I run <code>brew doctor &gt; brewErrors.txt</code>. I see the errors in my terminal but if I <code>cat brewErrors.txt</code> I just get a file with a few inlines. Is this a more general issue (say of Ruby or some kind of library/method of reporting) or a super narrow one? And for the future, if I ever encounter this how can I work around/fix this?</p>
