## Why The standalone installer validates package checksums with an awk interval expression. Older mawk releases do not support that expression, so they reject valid 64-character digests and report that the release manifest is missing an entry. This affects both x64 and ARM64 systems on common Debian-derived environments. Fixes #24219. ## What Changed Replace the awk interval expression with an explicit length check plus rejection of non-hexadecimal characters. This preserves the existing SHA-256 validation and lowercase normalization while working with older awk implementations. ## How to Test 1. Build and run the checksum predicate with mawk 1.3.4 20121129. 2. Confirm the old interval predicate rejects a valid 64-character digest. 3. Confirm the updated predicate accepts that digest. 4. Put the old mawk binary first on PATH as awk and run scripts/install/install.sh with an isolated HOME, CODEX_HOME, and CODEX_INSTALL_DIR. 5. Confirm Codex installs successfully and the installed binary reports version 0.140.0. 6. Verify the predicate rejects wrong-length digests, non-hexadecimal digests, and entries for another asset while accepting uppercase hexadecimal digests.
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.
