What is the difference between global and subcommand flags in Codex?

Global flags (like -a or -s) must be placed BEFORE the subcommand, while subcommand-specific flags (like --full-auto or --json) must come AFTER the 'exec' command.

How can I resume a previous Codex session using the CLI?

You can resume a session by using 'codex exec resume '. The session ID can be extracted from the JSONL output of a previous command.

What does the --full-auto flag do?

The --full-auto flag automatically sets the approval policy to 'on-request' and the sandbox mode to 'workspace-write', streamlining common development tasks.

How do I handle 'Permission Denied' errors in the sandbox?

Ensure you are using the '--full-auto' flag or explicitly setting '-s workspace-write' to allow file modifications within your project directory.

How do I start a non-interactive session with Codex CLI?

Use the 'codex exec' command followed by the '--full-auto' and '--json' flags to enable programmatic, non-interactive execution.
