conf.d — Personal Configuration Files

Keep your terminal configuration in one place.

Prerequisites

• tmux ≥ 2.1
• git
• zsh (macOS default), bash, or fish

Quick Start

curl -fsSL https://raw.githubusercontent.com/abienkowski/conf.d/master/setup.sh | bash

Then inside tmux press prefix + I (capital I) to install tmux plugins.

Selecting what to install

By default the script installs all three configs (tmux, vimrc, aliases). Set CONF_SETUP to a comma- or space-separated list to install only some. The variable must prefix the shell in the pipe (not curl):

# only tmux (+ TPM)
curl -fsSL https://raw.githubusercontent.com/abienkowski/conf.d/master/setup.sh | CONF_SETUP=tmux sh

# tmux and aliases
curl -fsSL https://raw.githubusercontent.com/abienkowski/conf.d/master/setup.sh | CONF_SETUP=tmux,aliases sh

CONF_SETUP=all (or unset/empty) installs everything. Unknown unit names abort the script and print the valid values.

Rebuild a machine (Nix / nix-darwin)

This repo also carries the Nix configuration that installs system packages and manages the shell across machines — see flake.nix and nix/. The goal is to keep one config common to all hosts, with machine-specific extras in a thin per-host module (currently nix/laptop.nix for this Mac).

On a new Mac

# 1. Install Nix
curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh

# 2. Clone this repo and link it as the nix-darwin config
git clone git@github.com:abienkowski/conf.d.git ~/conf.d
ln -s ~/conf.d ~/.config/nix-darwin

# 3. First-time bootstrap (applies system packages, home-manager, zsh, etc.)
nix run nix-darwin -- switch --flake ~/.config/nix-darwin

# 4. Later rebuilds
darwin-rebuild switch --flake ~/.config/nix-darwin

nix run nix-darwin … is used only for the very first switch; afterwards darwin-rebuild is installed and on PATH (run it with sudo if it asks).

The Nix configuration manages system packages and the shell (zsh, git identity, editor). The dotfiles themselves — aliases, tmux.conf, vimrc — are still installed by setup.sh on any machine, Nix or not (run it once, or install the files manually; ~/.aliases is sourced conditionally if present).

On a fresh machine there is no /opt/local-first PATH hack to remove — that legacy prepend was a MacPorts artifact and is gone. MacPorts itself is still reachable at /opt/local/bin (appended after the Nix dirs via home.sessionVariablesExtra).

Notes

• ansible-core is pinned to 2.18.13 in nix/laptop.nix (an overlay builds it against Python 3.13).
• nix/ modules: base.nix = shared system packages, home.nix = shared home-manager config, laptop.nix = per-host extras.

Manual Setup

git clone git@github.com:abienkowski/conf.d.git ~/conf.d
~/conf.d/setup.sh

What the Setup Script Does

1. Downloads the config files directly from GitHub (no clone needed when using the one-liner)
2. Backs up any existing ~/.tmux.conf, ~/.vimrc, ~/.aliases by renaming them in-place (e.g. .tmux.conf → .tmux.conf-YYYY-MM-DD). If a backup already exists for today, it's preserved and not overwritten.
3. Installs the selected config files into $HOME (see Selecting what to install)
4. Clones TPM to ~/.tmux/plugins/tpm (tmux unit only)
5. Adds source ~/.aliases to your shell's rc file (~/.zshrc, ~/.bashrc, etc.) (aliases unit only)
6. Prints post-install steps

The script is idempotent — running it again is safe.

Tmux Key Bindings

Binding	Action
C-a	Prefix (instead of default C-b)
C-a C-a	Send prefix to nested tmux session
C-b	Jump to last window
prefix r	Reload ~/.tmux.conf
prefix `	`
prefix -	Split pane vertically
prefix T	Swap current window to position 1
prefix C-a	Cycle to next pane
prefix h/j/k/l	Select pane left/down/up/right (vim-style)
prefix I	Install TPM plugins
prefix U	Update TPM plugins
prefix M-u	Clean uninstalled TPM plugins

Other settings:

• Mouse mode on, scrollback 10k lines, vi-style copy-mode
• Window numbering starts at 1
• Active window highlighted with cyan background

Aliases

Alias	Expands To
ll	ls -laF
k	kubectl (resolved at install time)
kns	kubens (resolved at install time)

Customizing

Edit the files in ~/conf.d/ then re-run the setup script to apply changes. If you want shell-specific aliases that aren't shared across machines, add them directly to your ~/.zshrc (or equivalent) instead of editing ~/conf.d/aliases.

Uninstall

# Remove installed files
rm ~/.tmux.conf
rm ~/.vimrc
rm ~/.aliases

# Remove TPM
rm -rf ~/.tmux/plugins/tpm

# Remove source line from shell rc (use your shell's rc: ~/.bashrc, ~/.config/fish/config.fish)
sed -i '' '/^source.*\/\.aliases/d' ~/.zshrc

Updating

If you used the one-liner, re-run it:

curl -fsSL https://raw.githubusercontent.com/abienkowski/conf.d/master/setup.sh | bash

Add CONF_SETUP=… in front of bash (after the pipe) to limit what is reinstalled. See Selecting what to install.

If you cloned the repo, pull and re-run:

cd ~/conf.d && git pull && ./setup.sh

The script is idempotent — it will skip files that haven't changed. After a tmux config update, reload with prefix r.
