Running Claude With Nobody Watching

Most people only ever use Claude while they are sitting in front of it.

Which means it stops working the moment you close the laptop, and every recurring job you hate still gets done by hand on a Monday.

There is a whole other mode. Print mode. No chat window, no approvals, just a command.

Pipe a log file into it and get JSON back,
Wrap it in a shell script and hand it to cron,
Drop it in as one step of a pipeline between two other commands,
Run it in CI so every pull request gets read before you do,
And wake up to a file that tells you exactly what it touched 🔥

I wrote up the whole thing. The one-liner, the cron entry, the wrapper script, the CI step, all copy-pasteable.

Plus the part nobody covers: what the permission model actually does when there is no human there to click yes, and the jobs that should never run unattended.

Free. No email wall.
