Ghidra CLI

A powerful Rust CLI tool for Ghidra reverse engineering, designed for Claude Code and other AI agents to efficiently analyze binaries.

Features

• 🚀 Universal Query System - Query any Ghidra data type with a single command
• 🔍 Advanced Filtering - Powerful filter language for precise data extraction
• 📊 Multiple Output Formats - JSON, CSV, TSV, Table, and more
• 🤖 LLM-Optimized - Designed for minimal token usage and maximum efficiency
• 🪟 Windows-First - Native Windows support with cross-platform compatibility
• 📦 Zero Configuration - Auto-detection of Ghidra installation

Installation

Prerequisites

• Ghidra 10.0 or later
• Rust 1.70+ (for building from source)

From Source

git clone https://github.com/yourusername/ghidra-cli
cd ghidra-cli
cargo build --release

The binary will be at target/release/ghidra.exe (Windows) or target/release/ghidra (Unix).

Setup

1. Run the initialization wizard:

ghidra init

2. Set your Ghidra installation (if not auto-detected):

set GHIDRA_INSTALL_DIR=C:\ghidra\ghidra_11.0

3. Verify installation:

ghidra doctor

Quick Start

# Quick analysis of a binary
ghidra quick malware.exe

# Import a binary
ghidra import suspicious.exe --project=analysis

# Query functions
ghidra query functions --program=suspicious.exe --filter="size>1000"

# Decompile a function
ghidra decompile 0x401000 --program=suspicious.exe

# List suspicious imports
ghidra dump imports --program=suspicious.exe --filter="name~Crypt OR name~Process"

Universal Query Command

The query command is the primary interface for data extraction:

ghidra query <data-type> [options]

Supported Data Types

• functions - All functions in the program
• strings - String data
• imports - Import table
• exports - Export table
• memory - Memory regions
• symbols - Symbol table
• xrefs - Cross-references
• comments - All comments
• types - Data types

Query Options

--filter="<expression>"   # Filter results
--fields=<list>           # Select specific fields
--format=<format>         # Output format
--limit=<n>               # Max results
--offset=<n>              # Skip first n results
--sort=<field>            # Sort order
--count                   # Just return count

Filter Language

# Comparison operators
name=malloc               # Exact match
size>1000                 # Greater than
address>=0x401000         # Greater or equal

# String operators
name~crypt                # Contains (case-insensitive)
name^sub_                 # Starts with
name$_exit                # Ends with
name=~"regex"             # Regex match

# Logical operators
name~crypt AND size>500   # AND
name~main OR name~start   # OR
NOT name^FUN_             # NOT

# Special operators
calls EXISTS              # Field exists
name IN [malloc,free]     # One of values
size>=100 AND size<=1000  # Range

LLM-Optimized Workflow

For Claude Code and other agents:

# 1. Count first (check result size)
ghidra query functions --program=malware.exe --count
# → 1,247 functions

# 2. Refine filter and count
ghidra query functions --program=malware.exe \
  --filter="NOT name^FUN_" \
  --count
# → 89 named functions

# 3. Get minimal data
ghidra query functions --program=malware.exe \
  --filter="NOT name^FUN_" \
  --fields=name,address \
  --format=json-compact

# 4. Deep dive on specific items
ghidra fn decompile <address> --program=malware.exe \
  --format=compact

Project Management

# Create project
ghidra project create myproject

# List projects
ghidra project list

# Delete project
ghidra project delete myproject

Scripting

Run Custom Scripts

# Run a Python script
ghidra script run my_analysis.py --program=malware.exe -- arg1 arg2

# Execute inline Python
ghidra script python "print(currentProgram.getName())" --program=malware.exe

# Execute inline Java
ghidra script java "println(currentProgram.getName());" --program=malware.exe

Built-in Scripts

The CLI includes built-in scripts for:

• Function listing
• Decompilation
• String extraction
• Import/Export tables
• Memory map
• Cross-references
• Program information

Windows-Specific Notes

Path Handling

The CLI handles both Unix-style (/) and Windows-style (\) paths automatically.

Ghidra Installation Detection

Auto-detection checks these locations:

• C:\Program Files\Ghidra
• C:\Program Files (x86)\Ghidra
• C:\ghidra
• Registry entries (if available)

Executable Detection

Supports common Windows formats:

• .exe - Executables
• .dll - Dynamic libraries
• .sys - System drivers

Performance Tips

1. Use --count first - Check result size before fetching data
2. Filter aggressively - Pre-filter on Ghidra side, not in your code
3. Select minimal fields - Use --fields to reduce data transfer
4. Use compact formats - json-compact or minimal for LLMs
5. Paginate large results - Use --limit and --offset

Troubleshooting

Ghidra Not Found

# Check doctor
ghidra doctor

# Set manually
set GHIDRA_INSTALL_DIR=C:\path\to\ghidra

# Or in config
ghidra config set ghidra_install_dir C:\path\to\ghidra

Analysis Timeout

# Increase timeout
set GHIDRA_TIMEOUT=600

# Or in config
ghidra config set timeout 600

Project Issues

# List projects
ghidra project list

# Delete and recreate
ghidra project delete myproject
ghidra project create myproject
