dotfiles

These are my dotfiles. Feel free to use whatever you want.

Bootstrap with sudo priveleges

# To test:
# docker run -it ubuntu:24.04 bash
apt-get update && apt-get install -y curl sudo
curl -fsSL https://raw.githubusercontent.com/simondanielsson/dotfiles/main/install.sh | bash
source $HOME/.local/bin/env

Bootstrap without sudo (HPC/Slurm clusters, via Nix)

Use install-nix.sh on shared nodes where you don't have root. It installs everything into ~/.nix-profile and ~/.local — no system-wide changes. Requires a writable /nix directory (ask your sysadmin or check if it already exists as a shared store on your cluster).

# Requires curl and git (pre-installed on most clusters)
curl -fsSL https://raw.githubusercontent.com/simondanielsson/dotfiles/main/install-nix.sh | bash

Notes

• Nix is sourced for all zsh sessions via ~/.zshenv (written by the script).
• To garbage-collect old Nix generations: nix profile wipe-history --older-than 7d && nix store gc

Bootstrap without sudo (Lustre/HPC clusters, via Spack)

Use install-spack.sh on clusters where /nix is unavailable or not writable (e.g. Lustre-based HPC systems). Spack is cloned entirely into your home directory — no root, no /nix required.

# Requires curl (or wget) and git (pre-installed on most clusters)
curl -fsSL https://raw.githubusercontent.com/simondanielsson/dotfiles/main/install-spack.sh | bash

Spack builds from source by default, so the first run can be slow. If your cluster already has a shared Spack installation, you can reuse its pre-built packages by adding it as an upstream before running the script:

spack mirror add cluster-upstream /path/to/cluster/spack/mirror

After either no-sudo script completes, configure your local ~/.ssh/config to launch zsh automatically for interactive sessions (avoids needing to change the login shell on the cluster):

Host my_cluster
    ...
    RequestTTY yes
    RemoteCommand zsh -l

Then reconnect and you'll drop straight into zsh with all tools available.

Notes

• Spack and ~/.local/bin are added to PATH via ~/.zshenv and ~/.bashrc.
• To activate the tool environment manually: spack env activate dotfiles
• To add a new package: spack add <pkg> && spack install
• To garbage-collect old Spack builds: spack gc
