About:
CRaSH is a shell designed for connecting to and managing Java virtual machines in real-time. It provides a syntax similar to GDB, allowing developers to inspect and manipulate the JVM's internal state. The tool is particularly useful for low-level diagnostics and interactive troubleshooting of Java applications.

Key Features:

GDB-like syntax for intuitive command execution
Connects to local or remote JVMs via JMX
Extensible with custom commands written in Java or Groovy
Supports standard operations like thread inspection and memory management

Use Cases:

Real-time debugging of production Java applications
Automating JVM diagnostics via shell scripts
Learning and inspecting JVM internals interactively

Alternatives:

jcmd – Part of the JDK, offers similar diagnostic capabilities but lacks a persistent interactive shell environment.
VisualVM – Provides a comprehensive GUI for JVM monitoring, whereas CRaSH offers a lightweight, command-line interface.
