automatically get a quit when running gdb in script

I tried to use gdb to debug a new process which is created by a script. In the linux shell, I tried this:

ps -ef | grep -i [m]yprocess |  awk '{print "gdb -p "  $2}'  | sh

Every time，gdb got a ‘quit’ automatically then quit:

***0xf7788430 in __kernel_vsyscall ()
Missing separate debuginfos, use: debuginfo-install glibc-2.17-105.i686 libgcc-4.8.3-10.i686
(gdb) quit
A debugging session is active.
    Inferior 1 [process 834] will be detached.
Quit anyway? (y or n) [answered Y; input not from terminal]***

What can I do to fix this?

You can do just

gdb -p `pgrep myprocess`

I guess weird behavior is the consequence of STDIN not being a terminal but a pipe from awk.
