## What it is
A small collection of command-line scripts for Linux/Unix system administrators, written mostly in Perl and Bash. It centralizes handy utilities like file-age reporting, cron output suppression, CIDR expansion, and duplicate file detection.

## Use cases
- show how long ago a file was modified in human-readable form
- suppress cron job output unless the command fails
- expand CIDR ranges into individual IP addresses
- find duplicate files by content hash
- check whether a directory is empty in a shell script
- expand abbreviated IPv6 addresses

## When to choose
- you are a sysadmin wanting small standalone utilities without heavy dependencies
- you want a curated personal toolkit of shell-friendly scripts
- you need quick one-off helpers for cron jobs, networking, or file checks

## When to avoid
- you need actively developed or feature-rich tools - the successor repo sysbox is preferred
- you need cross-platform (Windows/macOS-first) tooling
- you want polished, documented, packaged software with a clear license
