## Why Codex-created linked worktrees do not include ignored files from the main worktree. Bazel users who keep local overrides in `user.bazelrc` therefore lose those settings in every new worktree. The setup must also work on Windows and must not overwrite a file that already exists in the worktree. ## What changed The checked-in Codex environment now invokes `.codex/environments/setup.py`. The script resolves the main worktree and current worktree, then uses `copy_from_main_worktree_to_worktree(repo_relative_path)` to copy ignored files into new worktrees without overwriting existing destinations. `main()` currently copies `user.bazelrc`. Additional repository-relative paths can be added as further calls to the same helper. ## Validation - Ran the setup script in a linked worktree and confirmed it handles a missing main-worktree `user.bazelrc`. - Verified the helper copies a main-worktree file, preserves an existing worktree file, and creates parent directories for a nested path.
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
