This repo tracks shell configs, SSH settings, and editor dotfiles via a git repo hosted on a local Gitea server. On any machine, a single command restores the full environment: directories, environment variables, shell aliases, and symlinked config files.

Three scripts drive the system:

Script	Role
`scripts/setup_enterprise_ai_bash.sh`	First-time setup — creates the directory tree, writes shell config, initializes dotfiles repo, migrates files
`scripts/dotfiles_manager.sh`	Day-to-day management — add/remove tracked files, push/pull, SSH key handling, multi-machine bootstrap
`scripts/bootstrap.sh`	Restore shortcut — reloads shell config and runs `dotfiles sync` to pull latest changes
`install.sh`	New-machine restore — applies all symlinks after cloning; auto-generated by `dotfiles_manager.sh`

Directory Layout

setup_enterprise_ai_bash.sh creates the following structure under $HOME:

Machine Profiles

The setup supports two profiles selected at first-run (or via MACHINE_PROFILE=work|personal):

	`work`	`personal`
Cloud root	`~/OneDrive` (symlink to macOS mount)	`~/Cloud`
`CLOUD_ROOT`	`$HOME/OneDrive`	`$HOME/Cloud`
Extra vars	`ONEDRIVE_ROOT`	`PROTON_ROOT`, `GDRIVE_ROOT`
Extra aliases	`onedrive`	`cloud`, `proton`, `gdrive`
Committed?	No — written to `~/.bashrc.local`	No — written to `~/.bashrc.local`

Shell Config Layering

~/.bash_profile
  └── sources ~/.bashrc
        ├── ### ENTERPRISE_AI_ENV ###    ← shared vars (WORKSPACE, DATA_ROOT, MODEL_ROOT, …)
        ├── ### DOTFILES_ALIASES ###     ← dotfiles / dot / dots-sync / dots-push / dots-status
        └── sources ~/.bashrc.local      ← machine-specific (profile, cloud paths, MACHINE_HOST)

File	Committed to dotfiles?	Purpose
`~/.bashrc`	Yes	Shared env vars, aliases, loads `.bashrc.local`
`~/.bash_profile`	Yes	macOS login shell — sources `.bashrc`
`~/.bashrc.local`	No	Machine-specific overrides (profile, cloud paths)

~/.bashrc.local is written by setup_enterprise_ai_bash.sh and regenerated when running it again. It is listed in .gitignore and never pushed to the remote.

Key Environment Variables

Variable	Value	Set in
`WORKSPACE`	`$HOME/workspace`	`~/.bashrc`
`DATA_ROOT`	`$HOME/data`	`~/.bashrc`
`MODEL_ROOT`	`$HOME/models`	`~/.bashrc`
`HF_HOME`	`$MODEL_ROOT/huggingface`	`~/.bashrc`
`OLLAMA_MODELS`	`$MODEL_ROOT/ollama`	`~/.bashrc`
`DOTFILES_DIR`	`$HOME/dotfiles`	`~/.bashrc`
`DOTFILES_REMOTE`	`http://172.27.0.35:3000/kenjim/dotfiles`	`~/.bashrc`
`MACHINE_PROFILE`	`work` or `personal`	`~/.bashrc.local`
`MACHINE_HOST`	`hostname -s` output	`~/.bashrc.local`
`CLOUD_ROOT`	`~/OneDrive` or `~/Cloud`	`~/.bashrc.local`

Shell Aliases

Alias	Expands to
`ws`	`cd $WORKSPACE`
`src`	`cd $WORKSPACE/src`
`data`	`cd $DATA_ROOT`
`models`	`cd $MODEL_ROOT`
`cloud`	`cd $CLOUD_ROOT`
`dotfiles` / `dot`	`bash ~/scripts/dotfiles_manager.sh`
`dots-sync`	`dotfiles sync`
`dots-push`	`dotfiles push`
`dots-status`	`dotfiles status`

Bootstrap Flow

First-time setup on a new machine

# 1. Run the full setup wizard (creates dirs, shell config, dotfiles repo):
bash scripts/setup_enterprise_ai_bash.sh

# 2. Reload shell:
source ~/.bash_profile

The wizard will interactively:

Select a machine profile (work / personal)
Create the full directory tree
Write ~/.bashrc env block and ~/.bashrc.local
Initialize or clone the dotfiles repo from Gitea
Add dotfiles aliases to ~/.bashrc
Offer to migrate shell configs, .gitconfig, scripts into dotfiles
Offer SSH config setup + GPG key export
Offer to push everything to $DOTFILES_REMOTE
Offer Time Machine exclusions for ~/data/raw and ~/models
Offer to bootstrap a remote machine over SSH

Restore an existing setup on a new machine

# Clone the repo and run the portable restore script:
git clone http://172.27.0.35:3000/kenjim/dotfiles ~/dotfiles
bash ~/dotfiles/install.sh
source ~/.bash_profile

install.sh will:

Apply all symlinks listed in .dotfiles_manifest
Prompt for machine profile and run setup_enterprise_ai_bash.sh if no .bashrc.local exists
Prompt to GPG-decrypt any SSH private keys stored in dotfiles/.ssh/keys/*.gpg

Day-to-day sync

# Pull latest dotfiles from Gitea and reapply any new symlinks:
dotfiles sync          # or: bash ~/scripts/bootstrap.sh

# Push local changes:
dotfiles push "my change description"

# Check symlink health:
dotfiles status

Remote machine bootstrap (from this machine)

dotfiles remote-bootstrap user@hostname
dotfiles remote-bootstrap user@hostname --profile work

This uploads the scripts, then runs the full setup interactively over SSH.

Dotfiles Management — How Symlinks Work

~/dotfiles/.bashrc   ←──────────── ~/dotfiles/ (git repo)
      ↑
  symlink
      │
~/.bashrc            ←── shell reads this

dotfiles add <file> moves the file into ~/dotfiles/, creates a symlink at the original HOME location, and records the relative path in .dotfiles_manifest. dotfiles install re-creates all symlinks from the manifest (idempotent — safe to re-run). Conflicts are backed up to ~/.dotfiles_backup/<timestamp>/ before being replaced.

SSH Key Strategy

Item	Committed?	Details
`~/.ssh/config`	Yes	Shared SSH client configuration
`~/.ssh/*.pub`	Yes	Public keys are safe to store
`~/.ssh/id_*` (private)	No	Listed in `.gitignore`
`~/.ssh/keys/*.gpg`	Yes	GPG-encrypted private key backups

# Encrypt private keys and save to dotfiles:
dotfiles ssh-export

# Decrypt on another machine after sync:
dotfiles ssh-import

Gitea Authentication

HTTP push/pull uses a Personal Access Token saved locally (never committed):

dotfiles auth
# → Settings (avatar) → Applications → Generate Token → paste here

Credentials are stored at ~/.config/dotfiles/credentials (chmod 600).

Time Machine Exclusions

During setup you are offered the option to exclude large AI folders:

~/data/raw      — large raw datasets
~/models        — multi-GB model weights

To add manually:

sudo tmutil addexclusion ~/data/raw
sudo tmutil addexclusion ~/models
