Using zsh Modules

A lot of zsh functionality is contained in loadable zsh modules. I can’t cover all of the zsh modules in this chapter, so let’s just look at some of the more useful ones.

First, let’s see which modules get loaded into a zsh session by default:

ubuntu2404% zmodload
zsh/complete
zsh/computil
zsh/main
zsh/parameter
zsh/stat
zsh/terminfo
zsh/zle
zsh/zutil
ubuntu2404%

There are a lot more optional modules that you can load yourself by using the zmodload command, as we’ll see next.

To read about all of the available zsh modules, see the zshmodules man page.

Now, let’s get a bit more specific by looking at the mathfunc module.

Using the mathfunc Module

If you want to create some really fancy math scripts without having to use an external utility such as bc, just load the mathfunc module, like this:

ubuntu2404% zmodload zsh/mathfunc
ubuntu2404%

This module provides functions for trigonometry...
