[SOLVED] gdb help Arch Linux

I am reading a book and am trying to follow some examples, but I can't get gdb to work like it does in the book. In the book when gdb is run on the binary, it shows general registers etc... Here is the output on my computer which really shows nothing when gdb is run, any help would be awesome:

Code:

[test@localhost Programs]$ cat HelloWorld.c 
#include <stdio.h>
int main ()
{
        int i;
        for (i = 0; i < 10; i++)
                printf ("Hello World\n");
        return 0;
}
[test@localhost Programs]$ gcc -g HelloWorld.c 
[test@localhost Programs]$ ./a.out 
Hello World
Hello World
Hello World
Hello World
Hello World
Hello World
Hello World
Hello World
Hello World
Hello World
[test@localhost Programs]$ gdb -q a.out 
Reading symbols from a.out...done.
(gdb) q

Nevermind had to run some other commands like:

Code:

(gdb) break main
(gdb) run
(gdb) info registers

Those gdb commands give the output that I was looking at from the book, not sure how I missed that. Problem solved!

You have to type 'run' and enter to run the gdb on program.

Here is a good tutorial on using gdb.
