Insprired by a recent blog post of Bohidar Batsov I decided to simplify my Zshrc.
About 10ish years ago, I started to use Zsh and used the Oh-My-Zsh distribution for a pleasant OOTB experience. But over the years, I don’t really use most of the stuff, but never really took the time to clean it up, as having NO zsh config just leaves a very ugly prompt by default.
As Bohidar, I also added Starship as prompt. This provides a nice framework for customizing and extending the prompt.
You can find the full zshrc on my dotfiles. Stuff, that you need to install:
- Starship, I used cargo (Rust) to install it:
rustup update cargo install starship # make sure ~/.cargo/bin is in your $PATH - fzf. The FZF that is available on the Ubuntu repos is quite old, so I installed it via git:
git clone --depth 1 https://github.com/junegunn/fzf.git ~/.fzf ~/.fzf/install
In my case, I also needed to remove the system package, as it’s PATH priority would be higher than this installed version.
Starship
In the dotfiles repo, you can also find my Starship TOML. There is a couple of options that I disabled, like NodeJS version, Git “untracked” hint and removal of the verbose conjunctions, like “in” and “on” between it’s segments.
On the bottom, you can also find a SSH-Agent integration, that tells me, if my most important Keys are unlocked and ready to use (useful before Git-pushing, or ssh access to production machines).

Tangent: asdf upgrade
While running starship, I noticed that fetching the current Ruby version took about 250ms (time ruby -v). I am using the Ruby version manager asdf since a couple of years that I only noticed now took quite a long time to fetch the current version. Going on their Github repo, I saw, that the current version is a complete rewrite in Go, and supposedly much faster. So I decided to upgrade it. Fortunately, you can either compile with Go (which’s version on APT repos is also too old), or download the precompiled version, which I did:
wget https://github.com/asdf-vm/asdf/releases/download/v0.16.5/asdf-v0.16.5-linux-amd64.tar.gz
# or with Macos:
wget https://github.com/asdf-vm/asdf/releases/download/v0.16.5/asdf-v0.16.5-darwin-arm64.tar.gz
tar -xvzf asdf-v0.16.5-linux-amd64.tar.gz
sudo mv asdf /usr/local/bin
rm ~/.asdf/bin/asdf
Alternately, mise seems to be a very nice alternative to asdf.
