system maintenance

Shows how to pair AI with Bash to streamline system maintenance: using LLMs to draft, review, and harden scripts for updates, backups, log parsing, and anomaly detection; adding safety nets (dry runs, tests, least-privilege); scheduling with cron/systemd; wiring alerts and monitoring; and keeping prompts and code in version control. Includes examples, pitfalls, and best practices.

The article explains how to detect symbolic link loops in Linux using the `readlink -e` command, which is crucial for system maintenance and avoiding performance issues. Symbolic link loops occur when a symlink points directly or indirectly to itself, causing endless resolution attempts. The command helps identify these loops by fully resolving the symlink path and returning nothing if a loop is detected. Additional discussions include creating symlinks, software installation, and cross-platform compatibility of `readlink`.
