Current git `master` branch is `6.1.7`, next release will be `6.1.8`.

### Description

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

The **radare** project started as a simple command-line hexadecimal editor
focused on forensics. Today, r2 is a full-featured low-level command-line tool
with support for scripting with the embedded Javascript interpreter or via r2pipe.

r2 can edit files on local hard drives, view kernel memory, and debug programs
locally or via a remote gdb/windbg servers. r2's wide architecture support allows
you to analyze, emulate, debug, modify, and disassemble any binary.

## Installation

Download the last [released](https://github.com/radareorg/radare2/releases) binaries.

The recommended way to install radare2 is from Git repository source:

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

* Run `sys/install.sh` for the default acr+make+symlink installation
* meson/ninja (muon/samu also works) and make builds are supported.

### Source Build

* r2 can be installed from `git` or via `pip` using `r2env`.
* 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`

On Windows use the .bat scripts and msvc:

```bat
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
```

## Usage

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

```sh
$ r2 /bin/ls   # open file in read-only
> aaa          # analyse the program (r2 -A)
> afl          # list all functions (try aflt, aflm)
> px 32        # print 32 byte hexdump current block
> s sym.main   # seek to main (using flag name)
> f~foo        # filter flags matching 'foo' (internal |grep)
> iS;is        # list sections and symbols (rabin2 -Ss)
> pdf; agf     # disassembly and ascii-art function graph
> oo+;w hello  # reopen in read-write and write a string
> ?*~...       # interactive filter in all command help
> q            # quit
```

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 packages matching a word
r2pm -Uci <pkg> # update database and clean install a package
r2pm -u <pkg>   # uninstall the given package
r2pm -l <pkg>   # list installed packages
```
