## Summary - split the joined `PATH` before running system `bwrap` lookup - keep the existing workspace-local `bwrap` skip behavior intact - add regression tests that exercise real multi-entry search paths ## Why The PATH-based lookup added in #15791 still wrapped the raw `PATH` environment value as a single `PathBuf` before passing it through `join_paths()`. On Unix, a normal multi-entry `PATH` contains `:`, so that wrapper path is invalid as one path element and the lookup returns `None`. That made Codex behave as if no system `bwrap` was installed even when `bwrap` was available on `PATH`, which is what users in #15340 were still hitting on `0.117.0-alpha.25`. ## Impact System `bwrap` discovery now works with normal multi-entry `PATH` values instead of silently falling back to the vendored binary. Fixes #15340. ## Validation - `just fmt` - `cargo test -p codex-sandboxing` - `cargo test -p codex-linux-sandbox` - `just fix -p codex-sandboxing` - `just argument-comment-lint`
npm i -g @openai/codex
or brew install --cask codex
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
Install globally with your preferred package manager:
# 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.
