See the [Releases](https://github.com/radareorg/radare2/releases) page for
downloads. The current git `master` branch is `5.8.3`, next will be `5.8.4`.

* Since r2-5.6.0 all the patch releases are [abi stable](doc/abi.md)
* Odd patch versions are used in git builds only, releases use even numbers
* No need to recompile the plugins, bindings or tools if the major and minor version are the same

### Description

r2 is a complete rewrite of radare. It provides a set of libraries, tools and
plugins to ease reverse engineering tasks. Distributed mostly under LGPLv3,
each plugin can have different licenses (see r2 -L, rasm2 -L, ...).

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.

</p>

## Installation

* r2 can be installed from `git` or via `pip` using `r2env`.
* Run `sys/install.sh` for the default acr+make+symlink installation
* meson/ninja (muon/samu also works) and make builds are supported.
* Windows builds require meson and msvc or mingw as compilers
* To uninstall the current build of r2 run `make uninstall`
* To uninstall ALL the system installations of r2 do: `sudo make purge`

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

Default Windows builds use MSVC, so run those `.bat`:

```sh
preconfigure.bat       REM setup python, meson, ninja
configure.bat          REM run meson b + vs project
make.bat               REM run ninja -C b
prefix\bin\radare2.exe
```

Alternatively you can use r2env to switch between different versions.

```sh
pip install -U 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
```

## Plugins

Many plugins are included in r2 by default. But you can extend its capabilities
by using the [r2pm](https://github.com/radareorg/radare2-pm) package manager.

```sh
r2pm -s <word> # search package by word
r2pm -ci <pkg> # install a package
```

* [iaito](https://github.com/radareorg/iaito): The official Qt graphical interface
* [radius2](https://github.com/nowsecure/radius2): A fast symbolic execution engine based on boolector and esil
* [r2dec](https://github.com/wargio/r2dec-js): A decompiler based on r2 written in JS, accessed with the `pdd` command
* [r2ghidra](https://github.com/radareorg/r2ghidra): The native ghidra decompiler plugin, accessed with the `pdg` command
* [r2frida](https://github.com/nowsecure/r2frida): The frida io plugin. Start r2 with `r2 frida://0` to use it
