This repository contains scripts that I use to provision my new computers/servers that I use day-to-day.

I maintain it so that I can be productive within 10 minutes of encountering a new or re-installed PC.

The focus is on functionality. Features are only added, in minimal form, if I use them regularly.

General Tools

Purpose Tool(s) Comments
Task management dstask See section on time management below. Another mental offload -- see GTD
Text editing vim / neovim FZF integration with gruvbox theme and polyglot syntax pack.
Password management pass Secured with Yubikey and GnuPG2, synchronised with git. Mental offload as it is no longer necessary to remember dozens of passwords. Browserpass used for Firefox integration.
Code search ripgrep + fzf See rgfzf and vimfzf commands in scripts/ and bindings below.
Version control git GnuPG2 used for code signing. GPG agent forwarded to remote hosts with gssh
SSH Agent GnuPG2 Used with a Yubikey. See my set up guide.
Security device Yubikey 5 Used with GnuPG2 to hold GPG keys and SSH key. Also used for 2FA.
Note taking/minutes git + vim / neovim I use a git repository of markdown files to organise ideas and other notes. Yet another mental offload.
Personal cryptography GnuPG2 Used with a Yubikey. See my set up guide.
Shell bash/zsh I used to use fish but it's incompatible with bourne shell which makes maintenance a pain.
Terminal multiplexing tmux Bindings adjusted to match vim
Terminal Alacritty GPU accelerated and minimal. I also use uxterm.
Terminal Font Hack Switched from Adobe Source Code Pro as 0 and 8 were too similar
Window management i3wm Much faster than Unity, Gnome 3 etc as there are no animations. See openbox if you don't like tiling window managers.
Environment management direnv To set environment variables based on current directory tree

Specific tools

Purpose Tool(s) Comments
VPN wireguard managed with dsnet Wireguard is simple, fast and reliable. It will become the standard VPN.
Web browser firefox Fast since Quantum. Animations disabled for speed.
Disk space reclaim ncdu + tmpreaper Tools for clearing up disk space. I run the latter against ~/Downloads/ with a systemd user timer.
Server configuration ansible Idempotent, agentless configuration management. Used with git.
HTTP Client httpie curl alternative with better UX. Sometimes used with jq.
System backup restic
Cloud backup rclone
CAD OpenSCAD Limited but powerful if you plan ahead
CAD CadQuery B-REP kernel instead of just CSG. More powerful, currently learning.
Diagramming draw.io Diagram creation software. See also dia, graphviz, tikz.
SVG optimisation svgo Useful for inlining SVGs in a web page
Audio/video conversion sox + ffmpeg + gstreamer
Web crawling httrack Better than wget for crawling (i.e. it works)
Document conversion pandoc See also pdflatex, which I use for formal reports.
Static blog hugo Chosen in an attempt to make myself stop writing blog engines and write articles instead.
Git history viewer tig
Secret management git-crypt Used API secrets mainly.
Music library curation beets Automates curation of music library
CLI Benchmarking hyperfine
Secure file sending ffsend Terminal client for Firefox send
File watching entr Simpler than inotify-tools
ISO boot drive ventoy Allow booting of thousands of common ISOs from a flash drive. BIOS/uEFI, linux and windows

Notable features

  • Workflows and application configuration profiled for speed. See section on Latency for more information.
  • Prompt/hostname colour based on hostname to make it easy to distinguish between hosts.
  • SSH+GPG agent runs locally, forwarded remotely. SSH_AUTH_SOCK is synchronised between tmux sessions.
  • history is globally shared, as I use my history as a database to search
  • History is automaticall filtered: History is de-duplicated, most recent persists. History is also filtered leaving only useful commands. This increases the SNR in the history file about 5x, which makes searching the history using FZF quicker. History is only cleaned up on shell exit, so you won't lose your immediate history which allows for command correction.

Custom bindings

Binding Context Description
CTRL+p bash/zsh/vim Search current directory with FZF and launch editor with results. Tab to select multiple.
r <string> bash/zsh Search current directory with ripgrep for files containing <string>, filter with FZF and launch editor with results. Tab to select multiple.
CTRL+r bash/zsh History search using fzf.
tm bash/zsh Launch or connect tmux single session. This is automatic if there is already an unconnected session.
CTRL+s bash/zsh Prepend sudo to the prompt and move the cursor back to the end of the prompt.

See home/.aliases, bin/, home/.functions.sh and home/.tmux.conf for more handy shortcuts/wrappers/bindings.

OSes with automatic provisioning.

./.sh will set up a fresh install with all of my regular applications, system configuration and my user configuration.

Check the OSes specified in ./bootstrap.sh for an up-to-date list of OSes that have automatic provisioning. Note that the automatic provisioning may be in various different states of stability depending on what I'm currently using and if newer OS versions have been released.

One liners

Obviously inspect the script to see what it does before you run it. Note that it will clobber your settings files.

MacOS:

curl -sL https://github.com/naggie/dotfiles/raw/master/bootstrap.sh | sh && zsh

Ubuntu/Fedora:

wget -O - https://github.com/naggie/dotfiles/raw/master/bootstrap.sh | sh && zsh

FreeBSD:

fetch -qo - https://github.com/naggie/dotfiles/raw/master/bootstrap.sh | sh && zsh

Tips

  1. Run a vim selection through a command with :!cmd. Useful for formatting as well as copying on a mac: !pbcopy. Write from the clipboard with r!pbpaste.
  2. Keep useful local environment variables in ~/.env-local.sh

An excellent guide and background to a lot of the tools used here is the MIT missing semester.

Operational security

With major services being compromised more and more, good OPSEC is important. I use:

  1. 2FA (U2F) where possible
  2. A different password for every service (important to prevent attacker pivot)
  3. Yubikey (as an openPGP smartcard) to store my SSH and GPG keys. See my set up guide.
  4. Full-disk encryption for every device
  5. Lock-screen for every device
  6. Backup 2FA codes, backup passwords and master passwords are in a physical fire safe
  7. I may switch to a password manager (pass or Keepassxc)
  8. UBlock origin on Firefox
  9. HTTPS everywhere on Firefox
  10. Own web services configured with A+ rating from ssllabs (best cipher suite, protocol etc)
  11. Regular updates of all software
  12. Subscription to vulnerability mailing lists
  13. Don't forward SSH/GPG agent by default

LiveCD

On an ubuntu host, run remaster-livecd.sh with an xubuntu ISO to produce a remastered xubuntu LiveCD with dotfiles preinstalled. I use this preconfigured with ./install-naggie.sh to allow me to start using new or foreign PCs immediately.

It will soon be replaced with an arch equivalent.

Mode of operation

Dotfiles can provision a fresh install of an OS, or build a live/install CD. In order to manage the combinatorial complexity of supporting so many platforms, the install process has been changed to the following:

  1. bootstrap.sh -- Installs git and ensures the repository exists. Can operate independently from this repository. Uses sudo Detects platform and executes all of the next steps:
  2. provision.sh -- Runs the following scripts after sourcing utils.
  3. install-dependencies/* -- Installs dependencies for the given platform
  4. system-configuration/* -- Configures global system settings for all users for the given platform, eg keyboard layout. A UK keyboard and timezone is assumed.
  5. user-configuration.sh -- Installs generic user-specific configuration. No root required from now on.
  6. extras-naggie.sh -- Patches user configuration with configuration specific to my identity
