Ghidra CLI

A Rust CLI for automating Ghidra reverse engineering tasks. Usable directly by hand or driven by an AI coding agent like Claude Code.

Features

• Direct bridge architecture - CLI connects directly to a Java bridge running inside Ghidra's JVM
• Auto-start bridge - Import/analyze commands automatically start the bridge
• Fast queries - Sub-second response times with Ghidra kept in memory
• Program analysis - Functions, symbols, types, strings, cross-references
• Type system - Create/edit structs, enums, typedefs; add/remove struct fields
• Function signatures - Edit return types, calling conventions, full C signatures; retype variables
• Binary patching - Modify bytes, NOP instructions, export patches
• Call graphs - Generate caller/callee graphs, export to DOT format
• Search capabilities - Find strings, bytes, functions, crypto patterns
• Script execution - Run Java/Python Ghidra scripts, inline or from files
• Batch operations - Execute multiple commands from a file
• Responsive job control - Long analyses run on a serialized program lane while ping, status, jobs, and cancel stay live on a separate control plane
• Flexible output - Human-readable, JSON, or pretty JSON formats
• Filtering - Expression-based filtering with a small DSL (e.g., size > 100 AND name ~ 'crypt')

The CLI connects directly to a Java bridge running inside Ghidra's JVM. Ghidra loads once and stays resident, so one process holds all state: a rename or an applied type sticks for the next command instead of resetting each invocation, and queries return in-process with no per-command JVM startup. The bridge auto-starts on demand — any command brings it up, so you never launch it by hand.

Each project gets its own bridge process and port file, so you can analyze several binaries at once. The only runtime dependencies are Ghidra and a JDK — no Python/PyGhidra.

Installation

From Source

git clone https://github.com/akiselev/ghidra-cli
cd ghidra-cli
cargo install --path .

Requirements

• Ghidra 11+ - Download from ghidra-sre.org, or run ghidra setup to fetch it
• A full JDK - not a JRE. Ghidra compiles the bridge script at runtime, so it needs javac and the jdk.compiler module. Ghidra 12.x wants JDK 21; older releases accept JDK 17. ghidra doctor finds a suitable JDK and compiles the bridge as a health check.
• Rust 1.70+ - For building from source

Point the CLI at your Ghidra install (skip this if you used ghidra setup):

export GHIDRA_INSTALL_DIR=/path/to/ghidra
# Or store it in config:
ghidra config set ghidra_install_dir /path/to/ghidra

ghidra-cli picks the JDK itself and passes it to Ghidra, so you don't have to juggle PATH. Override the choice with the global --java-home flag, the java_home config key, or GHIDRA_CLI_JAVA_HOME.

Quick Start

# Check installation
ghidra doctor

# Import a binary. This starts the bridge and runs auto-analysis in one step.
ghidra import ./binary --project myproject --program mybinary

# Query functions (uses the running bridge)
ghidra function list

# Decompile a function
ghidra decompile main

# Find interesting strings
ghidra find string "password"

# Get cross-references
ghidra x-ref to 0x401000

# Generate call graph
ghidra graph callers main --depth 3

Global Flags

These work before any subcommand, so you can set them once for a whole invocation:

ghidra --project P --program bin function list   # --project/--program are global

Flag	Effect
--project <P>	Project name or path
--program <PROG>	Program within the project
--projects-dir <DIR>	Where Ghidra projects live (default: a cache dir; overrides ghidra_project_dir)
--java-home <PATH>	Full JDK for Ghidra to use (must be a JDK, not a JRE)
--json	Compact JSON output
--pretty	Pretty-printed JSON
-v / -vv / -vvv	Log verbosity: warn / info / debug
-q / --quiet	Suppress non-essential output

Ghidra 12.1+ rejects project directories that contain a dot-prefixed component (such as ~/.cache), so on Linux the default falls back to ~/ghidra-cli-projects. Use --projects-dir to put projects wherever you like.

Commands

Project & Program Management

ghidra project create <name>           # Create project
ghidra project list                    # List projects
ghidra project info [<name>]           # Show project info
ghidra project delete <name>           # Delete project (removes .gpr/.rep, stops its bridge)
ghidra import <binary> --project <p>   # Import + auto-analyze (bridge auto-starts)
ghidra import <binary> --no-analyze    # Import only, skip analysis (still persisted)
ghidra import <binary> --detach        # Return immediately; bridge keeps importing
ghidra analyze --project <p>           # (Re)run analysis on an imported program

Function Analysis

ghidra function list                   # List all functions
ghidra function list --filter "size > 100"  # Filter by size
ghidra decompile <name-or-addr>        # Decompile function
ghidra decompile main --with-vars --with-params  # Include variable/param details
ghidra disasm <address> --instructions 20  # Disassemble instructions
ghidra function set-signature <func> --signature "int foo(int x, char *y)"
ghidra function set-return-type <func> --type void
ghidra function set-calling-convention <func> --convention __cdecl
ghidra function set-var-type <func> --var local_10 --type "MyStruct *"

Decompilation has no native time limit by default, so large valid functions are not aborted after 30 seconds. Set GHIDRA_CLI_DECOMPILE_TIMEOUT to a positive number of seconds to impose a Ghidra-side limit; 0 means unbounded. The socket wait follows the long-operation policy controlled by GHIDRA_CLI_OP_TIMEOUT, which is also unbounded by default.

Symbols & Types

ghidra symbol list                     # List symbols
ghidra symbol create <addr> <name>     # Create symbol
ghidra symbol rename <old> <new>       # Rename symbol
ghidra type list                       # List data types (with kind: struct/enum/typedef/...)
ghidra type get <name>                 # Get type details (fields, enum members, typedef base)
ghidra type create <name>              # Create empty struct
ghidra type add-field <struct> --name fd --type int   # Add struct field
ghidra type del-field <struct> --name fd              # Remove struct field
ghidra type create-enum <name> --values "A=0,B=1"     # Create enum
ghidra type typedef <name> <base_type>                # Create typedef alias
ghidra type rename <old> <new>         # Rename type
ghidra type delete <name>              # Delete type

Function Tags

ghidra tag list                        # All tags (name, comment, use count)
ghidra tag get <name>                  # Functions carrying a tag
ghidra tag create <name> --comment "…" # Create a tag (comment optional)
ghidra tag add <func> <tag>...         # Attach tags (auto-creates missing ones)
ghidra tag remove <func> <tag>...      # Detach tags (--all clears every tag)
ghidra tag rename <old> <new>          # Rename everywhere it is used
ghidra tag set-comment <name> "…"      # Set/clear a tag's comment
ghidra tag delete <name>               # Delete tag, detaching from all functions
ghidra function list --tag <name>      # Filter by tag (repeatable = AND)
ghidra function list --untagged        # Functions with no tags

Tag names are case-sensitive. tag add/remove are idempotent (already-present and not-present tags are reported, not errors). Function rows include a sorted tags array, so --fields name,address,tags and --filter "tags ~ 'crypto'" work too.

Cross-References

ghidra x-ref to <address>              # References TO address
ghidra x-ref from <address>            # References FROM address

Search

ghidra find string "pattern"           # Find strings
ghidra find bytes "90 90 90"           # Find byte patterns
ghidra find function "*crypt*"         # Find functions by name
ghidra find crypto                     # Find crypto constants
ghidra find interesting                # Find interesting patterns

Call Graphs

ghidra graph calls                     # Full call graph
ghidra graph callers <func>            # Who calls this? (--depth optional)
ghidra graph callees <func>            # What does this call? (--depth optional)
ghidra graph export dot                # Export to DOT format

Binary Patching

ghidra patch bytes <addr> "90 90"      # Patch bytes
ghidra patch nop <addr> --count 5      # NOP out instructions
ghidra patch export -o patched.bin     # Export patched binary

patch nop --count N NOPs N consecutive instructions starting at the address (default 1), walking instruction by instruction so variable-length ISAs work. If any address in the run has no instruction, the whole patch rolls back untouched.

Comments

ghidra comment get <address>           # Get comment
ghidra comment set <addr> "note" --comment-type EOL  # Set comment
ghidra comment list                    # List all comments

--comment-type accepts EOL (default), PRE, POST, or PLATE.

Scripts

ghidra script list                     # List available scripts
ghidra script run myscript.py          # Run a script file
ghidra script run report.py -- arg1 arg2   # Pass positional args after --
ghidra script run dump.py --expect out.csv:10   # Fail unless out.csv has >=10 rows
ghidra script python "print(currentProgram)"   # Inline Python
ghidra script java "println(currentProgram);"   # Inline Java

script run resolves the path to an absolute location, forwards the args after -- to the script, and captures its stdout in the response. Use --expect PATH[:MIN_ROWS] (repeatable) to make the job fail when an output artifact is missing, empty, or short, and --allow-empty to permit an expected-but-empty file.

Batch Operations

ghidra batch commands.txt              # Run commands from file

Statistics

ghidra stats                           # Program statistics
ghidra summary                         # Program summary

Bridge Management

The bridge keeps Ghidra loaded in memory. It starts automatically when needed, but you can also control it manually:

# Start bridge with a program loaded
ghidra start --project myproject --program mybinary

# Check bridge status
ghidra status --project myproject

# Inspect active, queued, and recent jobs (or one job by ID)
ghidra jobs --project myproject
ghidra jobs 42 --project myproject

# Cooperatively cancel the active job, or select a queued/running job by ID
ghidra cancel --project myproject
ghidra cancel 42 --project myproject

# All commands use the bridge automatically
ghidra function list --project myproject    # Fast!
ghidra decompile main --project myproject   # Fast!

# Stop bridge
ghidra stop --project myproject

# Restart with different program
ghidra restart --project myproject --program otherbinary

The bridge handles networking and lifecycle controls independently from Ghidra
