OpenClaw Shell Commands and Cron Tasks Setup
OpenClaw can execute arbitrary shell commands on server where it's deployed. This makes it intelligent system task automator: server maintenance, script running, service management, event response.
Shell Tool
Agent executes bash/sh commands and analyzes output for next decisions. Chain: command → output → LLM analysis → next command. Complex conditional logic implemented without manual scripts.
Typical Tasks:
- Disk cleanup: find old files, check before deletion, report
- Service management: restart failed service, check status, notify
- Backup: create archive, upload to S3, check integrity, clean old
Cron Integration
Cron triggers OpenClaw agent by schedule. Example: every night agent checks disk space, free memory, service statuses, log file sizes, sends digest to Telegram.
Or OpenClaw manages crontab itself via shell commands — creates, modifies, deletes entries.
Security
Execution sandbox: command limiting by whitelist. Prohibition on rm -rf without explicit confirmation. All executed commands logged. Separate users with minimal rights for different agents.
