1. Same as baby step 1, `info function` then `disas main`

2. set breakpoint at main
```shell
gdb-peda$ b main
Breakpoint 1 at 0x40110e
```
3. Then run it (*NOTE: remember to `chmod +x debugger0_b` outside `gdb` first, or else you'll get permission denied*), it should stop at the first instruction of `main`
```shell
gdb-peda$ r

4. Here I originally thought [`ni`](https://cs.brown.edu/courses/cs033/docs/guides/gdb.pdf) will work, but after entering `ni` several times, I found that it have to [recurse many times](https://hackmd.io/URPao0CVTMC6gNn7K44_Uw#ni-part-ltendlessgt).
I then found that I should set another breakpoint at `ret` (which stands for *return*), so that I can get the final value of `eax` after the lengthy recursion.
```shell
gdb-peda$ b *0x401142
Breakpoint 2 at 0x401142
```
5. Then continue(which is `c`)
```shell
gdb-peda$ c
Continuing.

6. Here we can check where we are (though there's an arrow pointing at that line)
```shell
gdb-peda$ info registers rip
rip 0x401142 0x401142 <main+60>
```
*NOTE: `rip` stands for **instruction pointer register***
7. Now is the last step, print out the value of `eax` !
```shell
gdb-peda$ print/d $eax
$4 = 307019
```
#### `ni` part <endless>
```shell
db-peda$ ni
