+- GDB Basics: Use "si" to step into functions or "so" to step over functions, "info functions" to print all functions, "b [function]" (Example: "b main" to set a breakpoint and "b *0x1234" to set a breakpoint at addr 0x1234, "c" to continue program, "x/[dwords]x" to print offsets, for example "x/4x 0x1234" and "x/[dwords]x $reg" to print register contents, for example "x/4x $sp". Using pwndbg, you can use "rop" to list rop gadgets, for example "rop --grep 'pop {r3'" to list gadgets which pop values from stack to r3.
