Lean ZSH terminal

In the past two terminal posts (Enhance your macOS terminal and Enhance your macOS terminal - p10k) I showed how a fully-fledged terminal can look like. In this post, I'll concentrate on a lean terminal I'll for example use on my Raspberry PI boxes. This is how it should look like in the end:

Customized lean Terminal with oh-my-zsh

My Raspberry PIs are normally equipped with Raspbian in the minimal version. The standard shell on Debian is normally the bash shell, so we need to change it to ZSH first:

$ sudo apt-get clean all
$ sudo apt-get update
$ sudo apt-get -y install zsh zsh-autosuggestions zsh-syntax-highlighting
$ chsh -s $(which zsh)
$ grep $USER /etc/passwd

The last command should end with something like :/usr/bin/zsh indicating that ZSH is now the primary shell of the account. As I'm looking for a lean configuration I will only install oh-my-zsh and a third party theme.

$ sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

Finally, the third party theme needs to be installed. I used typewritten by reobin for this:

git clone https://github.com/reobin/typewritten.git $ZSH_CUSTOM/themes/typewritten

Once everything is installed and in place, the components need to be configured. This is done primarily through the .zshrc configuration file. Here is the one that creates the configuration from the screenshot above:

# Add local sbin to $PATH.

# Plugin configuration
# Standard plugins can be found in ~/.oh-my-zsh/plugins/*
# Custom plugins may be added to ~/.oh-my-zsh/custom/plugins/
# Add wisely, as too many plugins slow down shell startup.

Something about "lean" and "I will install oh-my-zsh" troubles me. OMZ is a beast.

 

I can't and I won't really argue against your statement, OMZ is indeed a beast and OMZ won't be lean any longer if you activate a big bunch of plugins. You have to be carefull with the plugins, the OMZ core itself is quite lean ... 😉
