In all honesty, `fzf` probably deserves a folder all on its own for its potential utility. Fzf is described as a general-purpose command-line fuzzy finder. More information of course can be found on the official [github](https://github.com/junegunn/fzf). 

Installation: 
```
sudo port install fzf
```

Here are a [list of examples](https://github.com/junegunn/fzf/wiki/examples) to implement using fzf to make search within your terminal blazing fast.
