What is headless mode in Claude Code?

Headless mode allows you to run Claude Code via the command line without an interactive user interface, making it suitable for integration into scripts, cron jobs, and automation pipelines.

Can I parse the output from Claude Code programmatically?

Yes, by using the --output-format json flag, Claude Code will return a structured JSON object that can be easily parsed by tools like jq or within languages like Python and Node.js.

How do I maintain context between multiple headless commands?

You can capture the session_id from a JSON output and use the --resume flag in subsequent commands to continue the conversation context programmatically.

How do I handle file edit permissions in non-interactive scripts?

You can use the --permission-mode flag with 'acceptEdits' to automatically approve file changes or 'bypassPermissions' to skip all interactive prompts entirely.
