`pwndbg` (/poʊndbæg/) is a GDB plug-in that makes debugging with GDB suck less, with a focus on features needed by low-level software developers, hardware hackers, reverse-engineers and exploit developers.
|
|
|
|
It has a boatload of features, see [FEATURES.md](FEATURES.md).
|
|
|
|
## Why?
|
|
|
|
Vanilla GDB is terrible to use for reverse engineering and exploit development. Typing `x/g30x $esp` is not fun, and does not confer much information. The year is 2022 and GDB still lacks a real hexdump command! GDB's syntax is arcane and difficult to approach. Windbg users are completely lost when they occasionally need to bump into GDB.
|
|
|
|
## What?
|
|
|
|
Pwndbg is a Python module which is loaded directly into GDB, and provides a suite of utilities and crutches to hack around all of the cruft that is GDB and smooth out the rough edges.
|
|
|
|
Many other projects from the past (e.g., [gdbinit][gdbinit], [PEDA][PEDA]) and present (e.g. [GEF][GEF]) exist to fill some these gaps. Each provides an excellent experience and great features -- but they're difficult to extend (some are unmaintained, and all are a single [100KB][gdbinit2], [200KB][peda.py], or [363KB][gef.py] file (respectively)).
|
|
|
|
Pwndbg exists not only to replace all of its predecessors, but also to have a clean implementation that runs quickly and is resilient against all the weird corner cases that come up. It also comes batteries-included, so all of its features are available if you run `setup.sh`.

|
## How?
|
|
|
|
Installation is straightforward:
|
|
|
|
```shell
|
|
git clone https://github.com/pwndbg/pwndbg
|
|
cd pwndbg
|
|
./setup.sh
|
|
```
|
|
|
|
Pwndbg is supported on Ubuntu 18.04, 20.04, and 22.04 with GDB 8.1 and later. We do not test on any older versions of Ubuntu, so `pwndbg` may not work on these versions. We may accept pull requests fixing issues in older versions on a case by case basis, please discuss this with us on [Discord](https://discord.gg/x47DssnGwm) first. You can also always checkout an older version of `pwndbg` from around the time the Ubuntu version you're interested in was still supported by Canonical, or you can attempt to build a newer version of GDB from source.
|
|
|
|
Other Linux distributions are also supported via `setup.sh`, including:
|
|
|
|
* Debian-based OSes (via apt-get)
|
|
* Fedora and Red Hat (via dnf)
|
|
* Clear (via swiped)
|
|
* OpenSUSE LEAP (via zypper)
|
|
* Arch and Manjaro (via community AUR packages)
|
|
* Void (via xbps)
|
|
* Gentoo (via emerge)
|
|
|
|
If you use any Linux distribution other than Ubuntu, we recommend using the [latest available GDB](https://www.gnu.org/software/gdb/download/) built from source. You can build it as:
|
|
```
|
|
cd <gdb-sources-dir>
|
|
mkdir build
|
|
cd build
|
|
../configure --disable-nls --disable-werror --with-system-readline --with-python=`which python3` --with-system-gdbinit=/etc/gdb/gdbinit --enable-targets=all
|
|
make -j7
|
|
```
|
|
|
|
## What can I do with that?
