Yes, try something like this,

define macro1
   b main
   r
   next
   next
   next
end

Put that in your .gdbinit file and then start up GDB and type 'macro1'
to get it to execute the commands.

Hello,

You may also want to take a look at automatic display, which can also 
and save you lots of keystrokes.

See http://sources.redhat.com/gdb/current/onlinedocs/gdb_9.html#SEC62 
for more details,

Cheers,

Vincent

You need to use command hooks (see section 20.2 of UsersGuide for 
details).

I.e. putting this in your .gdbinit will print registers automatically on 
each "next" command:

  define hook-next
  info registers
  end


Best regards,
Konstantin.

Is there a way to define a macro?

[wmaple]

Hi.

When I debug a program on disassambly level, for inspecting registers or memory units, I have to enter same commands again and again. For example, after execution of each instruction, I want to inspecting all common registers. So, every time, I have to enter command 'info register' several times. Is there a way to define a macro, by which I can enter these commands conveniently.

Thanks!
