What issue are you seeing?
After starting codex, cannot do anything, even on a trivial project folder with just a README.md file. If I ask 'Display the README.md' it tries all kinds of things and eventually gives up and says: "• I’m unable to run any shell commands right now — even echo test is timing out in this environment. Can you check whether the command runner is functioning, or share the README.md contents directly?"
mkdir -p /tmp/codex-smoke && cd /tmp/codex-smoke && echo hi > README.md
codex → Approval mode Agent (current) (workspace sandbox)
Ask “run echo test” → returns (no output) then times out
codex sandbox macos -- /bin/echo test works
!echo test works
Agent (full access) works

The agent is attempting to execute shell commands, but they are all timing out. This appears to be a configuration issue in your system, perhaps with your bash configuration scripts? You'll need to do some debugging on your system to figure out the underlying cause.
Closing outdated bug.
