If you're really struggling to find information, and you're resorting to
searching large swathes of files, then ag (the silver searcher) is
brilliant. It works similarly to grep ("ag table-cache /etc"), but it
runs a lot faster than grep because of a few tricks (certain hidden
folders such as .svn, .git etc are skipped, it uses threads and
memory-mapping to read files just about as fast as they can come off the
disk and it's code is regularly profiled to achieve the best speed).

You can get ag directly from Github
<https://github.com/ggreer/the_silver_searcher>, or you can look there
for instructions on how to install it on your favourite OS (Linux,
MacOS, Windows ...)
