A collection of utility scripts for various system administration and automation tasks.

Scripts

Script	Description	Documentation
Cluster SSH Key Setup	Automates SSH key distribution across a cluster of nodes	README
Cluster System Update	Runs apt update/upgrade in parallel across cluster nodes	README
Docker Image Update	Automates the process of updating a running Docker container	README
Cloudflare IP Logger	A reverse proxy that logs visitor IPs from Cloudflare Tunnel traffic	README
Ollama Model Updater	Checks for updates to available models on ollama.ai and installs them automatically	README
Git Update	A bash script to interactively manage Git repositories across GitHub and GitLab with clone, fetch, and push operations—individually or in batch.	README
Power & Temp Monitor	Monitor temperature, voltage, power, and throttling status on Raspberry Pi, Nvidia Jetson, and x86 systems using Prometheus and Alertmanager	README
Alias Distribute	Distributes bash aliases to all nodes listed in /etc/hosts	README
Git Star Repo	A Python script that fetches all your GitHub starred repositories and generates a summary report with statistics and a full listing.	README
Dot Files	Personal configuration files for setting up a new Linux system.	README
Hung Connections	A utility for detecting and terminating hung network connections on Unix-based systems. Available in both Python and Bash	README
Health Check	A single-file bash script that performs a comprehensive system health check and simultaneously exports every measured value to a CSV (for trend analysis) and a JSON snapshot (for tooling integration). Run it on a schedule and pipe the CSV into pandas, Grafana, Excel, or gnuplot to watch metrics evolve over time	README
Chowned Thottled	A performance-conscious bash script for recursively changing file ownership across multiple directories on high-throughput systems. Designed to run safely alongside active workloads by controlling CPU and I/O priority, batching filesystem operations to avoid argument list limits, and skipping files that are already correctly owned	README
Linux Troubleshooting	A comprehensive, interactive shell script for diagnosing and troubleshooting x86_64 Linux servers. Covers 15 diagnostic modules ranging from hardware inventory and network connection analysis to Kubernetes cluster health and security auditing — all from a single script with no external dependencies beyond standard Linux tooling	README
File Retention (Age Off)	A config-driven bash script for age-based file cleanup across multiple directories. Each directory can have its own retention policy, glob pattern, and recursion setting — all managed from a single config file without touching the script itself	README
Dir Sync	A lightweight Python script that compares two directories and copies only the changed or new files (deltas) from source to destination. No external dependencies — stdlib only	README
