## What it is
A collection of handy shell and Java utility scripts that automate common developer tasks, such as finding CPU-hungry Java threads and duplicate classes in jars. It is installed via a self-installer and used in production environments at companies like Alibaba.

## Use cases
- find which java thread is consuming high cpu
- print thread stack for busy java threads
- find duplicate classes across jar files
- search for a class or resource inside jars
- copy command output to clipboard from terminal
- colorize cat output for readability

## When to choose
- you debug Java performance issues from the command line
- you want lightweight scripts instead of full APM tooling
- you need quick jar/class conflict diagnosis on Linux or macOS servers

## When to avoid
- you need a GUI-based profiler or continuous monitoring
- you work primarily on Windows without a POSIX shell
- you need managed, long-term metrics collection rather than ad-hoc troubleshooting
