Run command at gdb breakpoint, neither c or cont works

问题

I'm trying to run a command that prints information when a breakpoint is hit:

(gdb) break XXX
(gdb) command
> printf "xx=%p, yy=%d\n", p1, p2
> end

It seems to work, I see lots of outputs.

But suddenly it stopped working, and I saw a line says:

---Type <return> to continue, or q <return> to quit---

Am I missing something? I don't need to see anything on the screen now, 'cause I already enabled logging in gdb.

But suddenly it stopped working, and I saw a line says:

Try run set pagination off or set height unlimited before you run your program. This is from doc:

If you specify a height of either unlimited or zero lines, GDB does not pause during output no matter how long the output is. This is useful if output is to a file or to an editor buffer. ... Turning pagination off is the alternative to set height unlimited.
