I gave Codex the following bug report about the logic to report the host's resources introduced in https://github.com/openai/codex/pull/11488 and this PR is its proposed fix. The fix seems like an escaping issue, mostly. --- The logic to print out the runner specs has an awk error on Mac: ``` Runner: GitHub Actions 1014936475 OS: macOS 15.7.3 Hardware model: VirtualMac2,1 CPU architecture: arm64 Logical CPUs: 5 Physical CPUs: 5 awk: syntax error at source line 1 context is {printf >>> \ <<< "%.1f GiB\\n\", $1 / 1024 / 1024 / 1024} awk: illegal statement at source line 1 Total RAM: Disk usage: Filesystem Size Used Avail Capacity iused ifree %iused Mounted on /dev/disk3s5 320Gi 237Gi 64Gi 79% 2.0M 671M 0% /System/Volumes/Data ``` as well as Linux: ``` Runner: GitHub Actions 1014936469 OS: Linux runnervmwffz4 6.11.0-1018-azure #18~24.04.1-Ubuntu SMP Sat Jun 28 04:46:03 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux awk: cmd. line:1: /Model name/ {gsub(/^[ \t]+/,\"\",$2); print $2; exit} awk: cmd. line:1: ^ backslash not last character on line CPU model: Logical CPUs: 4 awk: cmd. line:1: /MemTotal/ {printf \"%.1f GiB\\n\", $2 / 1024 / 1024} awk: cmd. line:1: ^ backslash not last character on line Total RAM: Disk usage: Filesystem Size Used Avail Use% Mounted on /dev/root 72G 50G 22G 70% / ```
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 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.
