Claude Code fails to write to /tmp in non-interactive mode

By PulseAugur Editorial · [1 sources] ·

A user encountered an issue where Claude Code, when run non-interactively via a systemd timer, failed to write logs to the /tmp directory. The problem stemmed from Claude Code's file access being scoped by its working directory and explicit additions, rather than the user's UID, and the need for explicit permission prompts in interactive mode. When run without user interaction, these prompts are denied, causing the write operation to fail silently. Additionally, systemd's PrivateTmp=yes setting can create a private /tmp namespace for services, further isolating log files. The solution involved moving the log file destination out of /tmp to a user-accessible directory. AI

    Claude Headless Sandboxing: Why /tmp Writes Fail in Non-Interactive Mode

    <p>A scheduled Claude Code job that writes its report to <code>/tmp/agent_log.md</code> works every time you run it by hand. Under a systemd timer with <code>claude -p</code>, it exits 0, the journal shows no errors, and the file is either missing or empty.</p> <p>That's the whol…
