Bash Tips and Tricks

We are running modern computers with lots of memory and storage space: we might as well preserve our bash history forever (or at the very least for a very long time). This gives us an opportunity to do reverse search, and thus avoid typing same commands over and over. It also helps with forensics, in case you need to find out what went wrong with your system.
