title: Accidentally overwrote `pod` command in Terminal
body: <p>I accidentally overwrote the <code>pod</code> command in my <em>bash</em> by following this <a href="http://book.realworldhaskell.org/read/extended-example-web-client-programming.html" rel="nofollow">tutorial in Real World Haskell</a> and now I can't use <em>Cocoapods</em> any more. The tutorial showed how to build a cmd line podcast client and I installed it system-wide without thinking about the nameclash using the Haskell environment and the command <code>runghc Setup.hs install</code>. Does anyone know how I can restore the command (maybe just delete the new <code>pod</code> command that was installed)? </p>
