How to break assembly instructions at a given address in gdb?

Question

0x0000000000400448 <main+0>: push %rbp 0x0000000000400449 <main+1>: mov %rsp,%rbp 0x000000000040044c <main+4>: mov $0x6,%eax 0x0000000000400451 <main+9>: leaveq 0x0000000000400452 <main+10>: retq 

I tried:

 breaki 0x0000000000400448 

but it seems that there is no such command.

Is there such a gdb function?

Answer 1

try break *0x0000000000400448

Answer 2

Another way:

break *main+4

This will add a breakpoint at 0x000000000040044c
I think this is easier than writing the whole address!
