 With the classic `cd`, I will have to type the whole path.
 With `cd` aliased to `zoxide`, I only need to type `cd n` (supposing that `~/.config/nix` is the most frequently visited directory among all matched directories).

 Internally `zoxide` records my visits to directories in a SQLite database and sorts them based on frequency. If the first hit is not what I want, I can also interactively select from the matched list.

 `du` is quite basic, and I usually need to add several arguments to make it somewhat usable. For example, `-d 1` to control the depth, `-h` to make the size human-readable.

 [`ncdu`](https://dev.yorhel.nl/ncdu) is an interactive alternative to `du`, and is very usable out of the box. Interestingly, I also feel it is a touch faster than `du`.
 It can totally be an alternative to those fancy disk space analyzers as well.

 [`btop`](https://github.com/aristocratos/btop) might be the most "nerdy-looking" `top` alternative out of the box. It can be a handy tool if you are trying to make people believe you are a hacker.

 At the same time, it is very feature-rich and configurable. To some extent, it is also an alternative to bandwidth monitoring tools like `iftop` and disk utilization tools like `df`.
 
 ## `ls` -> `eza`
 
 I think there is nothing wrong with the classic `ls`. So, as an alternative, [`eza`](https://github.com/eza-community/eza) just has a few quality-of-life improvements, like file type icons, Git status, and (based on personal taste) prettier colors.
