## Why `codex-rs/core/src/tools/runtimes/shell/unix_escalation.rs` previously located `codex-execve-wrapper` by scanning `PATH` and sibling directories. That lookup is brittle and can select the wrong binary when the runtime environment differs from startup assumptions. We already pass `codex-linux-sandbox` from `codex-arg0`; `codex-execve-wrapper` should use the same startup-driven path plumbing. ## What changed - Introduced `Arg0DispatchPaths` in `codex-arg0` to carry both helper executable paths: - `codex_linux_sandbox_exe` - `main_execve_wrapper_exe` - Updated `arg0_dispatch_or_else()` to pass `Arg0DispatchPaths` to top-level binaries and preserve helper paths created in `prepend_path_entry_for_codex_aliases()`. - Threaded `Arg0DispatchPaths` through entrypoints in `cli`, `exec`, `tui`, `app-server`, and `mcp-server`. - Added `main_execve_wrapper_exe` to core configuration plumbing (`Config`, `ConfigOverrides`, and `SessionServices`). - Updated zsh-fork shell escalation to consume the configured `main_execve_wrapper_exe` and removed path-sniffing fallback logic. - Updated app-server config reload paths so reloaded configs keep the same startup-provided helper executable paths. ## References - [`Arg0DispatchPaths` definition](https://github.com/openai/codex/blob/e355b43d5c2a771f045296a6deae10d7c9c36ec6/codex-rs/arg0/src/lib.rs#L20-L24) - [`arg0_dispatch_or_else()` forwarding both paths](https://github.com/openai/codex/blob/e355b43d5c2a771f045296a6deae10d7c9c36ec6/codex-rs/arg0/src/lib.rs#L145-L176) - [zsh-fork escalation using configured wrapper path](https://github.com/openai/codex/blob/e355b43d5c2a771f045296a6deae10d7c9c36ec6/codex-rs/core/src/tools/runtimes/shell/unix_escalation.rs#L109-L150) ## Testing - `cargo check -p codex-arg0 -p codex-core -p codex-exec -p codex-tui -p codex-mcp-server -p codex-app-server` - `cargo test -p codex-arg0` - `cargo test -p codex-core tools::runtimes::shell::unix_escalation:: -- --nocapture`

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.
