I want to demo my program using gdb and a makefile script, but make won't execute further commands after gdb

Here is my makefile code

all: ass3

ass3: ass3.asm
    nasm -f elf ass3.asm
    ld -m elf_i386 -s ass3.o -o demo
    echo Start debugging\n
    gdb demo
    echo Breakpoint after first case has been calculated\n
    b *0x804809e
    echo Printing 1st case answer\n
    i ecx
    echo Breakpoint after second case has been calculated\n
    b *0x80480ba
    i ecx
    echo Breakpoint on third case showing the execution path when the difference of time    is negative\n
    b *0x8048113
    echo Since Initial time is large than final time, it will jump to an error catcher\n
    r
    echo Program caught the error and terminated the program\n

binaries = demo

clean: 
    rm -f $(binaries) *~

When I type make, it stops on gdb and when I press "q" (which is quit), It just proceeds executing the echo until it stops on b *0x804809e which is a gdb command

How do I make my makefile code do a demo run on gdb?

gdb starts its own prompt so you can't interact with it directly.

It reads .gdbinit on launch after starting so you can modify that to automate it.

Edit :

These questions might help you :

  1. What are the best ways to automate a GDB debugging session?
  2. Where is .gdbinit is located and how can I edit it?
