pwndbg VS peda

By far the best debugger for C is gdb+pwndbg (https://github.com/pwndbg/pwndbg)

There are a lot of these types of tools already in the reverse engineering community (in order of lowest chance of breaking when you throw really weird stuff at it):

GEF: https://gef.readthedocs.io/en/master/

PWNDBG: https://github.com/pwndbg/pwndbg

PEDA: https://github.com/longld/peda

They also come with a slew of different features to aid in RE/exploit dev, but many of them are also useful for debugging really weird issues.

GDB is great. I definitely recommend checking out watchpoints as well, a very useful tool for monitoring how a variable changes over time.

GDB also has many good plugins - pwndbg has tons of features and UI improvements over stock GDB.

I've recently started a new semester for my Master's program, and the first project for the semester involves using the GDB tool (GNU Debugger) to analyze a stack on a simple C program that contains a buffer overflow vulnerability. A couple of semesters ago, I had been given a VM pre-loaded with a more featured debugger tool called pwndbg. Pwndbg was excellent because it was easy to use and easily allowed accessed to information such as current assembly code being executed and a view of the program registers. So, going back to using GDB felt a little like stepping back into the stone age.

Pwndbg - A GDB plugin that provides a suite of utilities to hack around GDB easily.

i have peda installed on my gdb and now i am trying to install pwndbg with git clone https://github.com/pwndbg/pwndbg cd pwndbg ./setup.sh

Looks like they are using PEDA.

PEDA - GDB plugin (only python2.7).

peda - Python Exploit Development Assistance for GDB.

Did you follow the instructions? Step 2 adds PEDA to your ~/.gdbinit so it will/should load every time you open gdb. So if it doesn't work check your ~/.gdbinit file.
