## Radare2: Unix-Like Reverse Engineering Framework

[![Latest packaged version](https://repology.org/badge/latest-versions/radare2.svg)](https://repology.org/project/radare2/versions) [![Tests Status](https://github.com/radareorg/radare2/workflows/CI/badge.svg?branch=master)](https://github.com/radareorg/radare2/actions/workflows/ci.yml?query=branch%3Amaster) [![build](https://github.com/radareorg/radare2/actions/workflows/build.yml/badge.svg)](https://github.com/radareorg/radare2/actions/workflows/build.yml) [![tcc](https://github.com/radareorg/radare2/actions/workflows/tcc.yml/badge.svg?branch=master)](https://github.com/radareorg/radare2/actions/workflows/tcc.yml)

See the [Releases](https://github.com/radareorg/radare2/releases) page for
binary downloads. The current git `master` branch is `5.6.5`, and the next
release will be `5.6.6`.

r2 is a complete rewrite of radare. It provides a set of libraries, tools and
plugins to ease reverse engineering tasks.

The radare project started as a simple command-line hexadecimal editor focused
on forensics. Today, r2 is a featureful low-level command-line tool with
support for scripting. r2 can edit files on local hard drives, view kernel
memory, and debug programs locally or via a remote gdb server. r2's wide
architecture support allows you to analyze, emulate, debug, modify, and
disassemble any binary.

## Installation

r2 can be installed via `git` or `pip`.

```sh
git clone https://github.com/radareorg/radare2
radare2/sys/install.sh
```

```sh
pip install r2env
r2env init
r2env add radare2@git
```

## Usage

These are the first steps to use r2, read the book or find tutorials for more details

```sh
$ r2 /bin/ls   # open the binary in read-only mode
> aaa          # same as r2 -A, analyse the binary
> afl          # list all functions (try aflt, aflm)
> px 32        # print 32 byte hexdump current block
> s sym.main   # seek to the given offset (by flag name, number, ..)
> f~foo        # filter flags with ~grep (same as |grep)
> iS;is        # list sections and symbols (same as rabin2 -Ss)
> pdf; agf     # print function and show control-flow-graph in ascii-art
> oo+;w hello  # reopen in rw mode and write a string in the current offset
> ?*~...       # interactive filter all command help messages
> q            # quit
```
