 Zsh-z is a command line tool that allows you to jump quickly to directories that you have visited frequently in the past, or recently -- but most often a combination of the two (a concept known as ["frecency"](https://en.wikipedia.org/wiki/Frecency)). It works by keeping track of when you go to directories and how much time you spend in them. It is then in the position to guess where you want to go when you type a partial string, e.g., `z src` might take you to `~/src/zsh`. `z zsh` might also get you there, and `z c/z` might prove to be even more specific -- it all depends on your habits and how much time you have been using Zsh-z to build up a database. After using Zsh-z for a little while, you will get to where you want to be by typing considerably less than you would need if you were using `cd`.
 
 Zsh-z is a native Zsh port of [rupa/z](https://github.com/rupa/z), a tool written for `bash` and Zsh that uses embedded `awk` scripts to do the heavy lifting. It was quite possibly my most used command line tool for a couple of years. I decided to translate it, `awk` parts and all, into pure Zsh script, to see if by eliminating calls to external tools (`awk`, `sort`, `date`, `sed`, `mv`, `rm`, and `chown`) and reducing forking through subshells I could make it faster. The performance increase is impressive, particularly on systems where forking is slow, such as Cygwin, MSYS2, and WSL. I have found that, in those environments, switching directories using Zsh-z can be over 100% faster than it is using `rupa/z`.
