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
