Reversing with GDB (GNU Debugger) - Retro Reversing (Reverse Engineering)
August 28, 2020 - Not all emulators have support for GDB out of the box, which is a shame as it is an incredibly useful feature for reverse engineering. Luckily most good emulators are open source so we can in theory add GDB support ourselves! Marcin Mikołajczyk has a good tutorial on how to add GDB support ...

Using GDB for Reverse Engineering
gdb is a debugger commonly used when programming, but it is also useful for reverse engineering binary code. It lets you step through the assembly code as it runs, and examine the contents of registers and memory. You can also set breakpoints at arbitrary positions in the program.

Reverse-engineering: Using Linux GDB | by Rick Harris | Medium
May 20, 2016 - GDB, the GNU Project debugger, allows you to see what is going on `inside’ another program while it executes — or what another program was doing at the moment it crashed. When reverse engineering a program, the tool is used to review the compiled Assembly code in either the AT&T or Intel flavors to see step-by-step what is happening.

Reversing a binary using GDB: tutorial for Reverse Engineers | LevelBlue
November 3, 2021 - Reversing binaries is an essential skill if you want to pursue a career as exploit developer, reverse engineer or programming. The GNU Project debugger is a widely used debugger for debugging C and C++ applications on UNIX systems. A debugger is a developer's best friend to figure out software bugs and issues. This tutorial intends to be beneficial to all developers who want to create reliable and fault-free software. A debugger executes several programs and allows the programmer to manage them and analyze variables if they cause issues. GDB enables us to execute the program until it reaches a specific point.

December 20, 2019 - This process is called reverse engineering. Let's run the program and figure out its functionality. user@protostar:~$ ./rev HacksLand user@protostar:~$ It just prints a string "HacksLand" and simply exits. Can you imagine what type of code this is? We can assume it might look like the following. We don't know for sure, but let's imagine: #include <stdio.h> int main(){ printf("HacksLand\n"); return 0; } Now let's start our actual reversing process. We can use GDB for this.

If you want to learn reverse engineering on Linux, I highly recommend: Learning Linux Binary Analysis.
It is the only book (that I know of) that goes in depth on the ELF format.

First start gdb from a shell prompt:
$ gdb bomb
Then run your program from the (gdb) prompt with the command line you want:
(gdb) run model.abc
You need to launch your program this way because gdb doesn't allow you to specify command line arguments for your program on the gdb command line.

Another, more convenient way of debugging a program with arguments:
gdb --args program <arguments>
If you don't have symbols, you'll have to start from the entry point. To figure our where it is, use:
(gdb) info file
Symbols from "/.../tesprog".
Local exec file:
`/.../tesprog', file type elf32-i386.
Entry point: 0x804abc0
Then you can set breakpoint on it before running:
break *0x804abc0
Note that the entry will be most often the library startup code (ctr0.s), it might take a while to get to the actual code written by the programmer.
