Building on shamrock's answer, you could merge this into one line if you're running bash:

comm -12 <(sort file_a) <(sort file_b)

The <( ) construct creates a temporary file out of the output of the command(s) inside the parens.

ZMQ_MSG_MOVE(3) 						    0MQ Manual							   ZMQ_MSG_MOVE(3)

NAME
zmq_msg_move - move content of a message to another message SYNOPSIS
int zmq_msg_move (zmq_msg_t *dest, zmq_msg_t *src); DESCRIPTION
The zmq_msg_move() function shall move the content of the message object referenced by src to the message object referenced by dest. No actual copying of message content is performed, dest is simply updated to reference the new content. src becomes an empty message after calling zmq_msg_move(). The original content of dest, if any, shall be released. Caution Never access zmq_msg_t members directly, instead always use the zmq_msg family of functions. RETURN VALUE
The zmq_msg_move() function shall return zero if successful. Otherwise it shall return -1 and set errno to one of the values defined below. ERRORS
EFAULT Invalid message. SEE ALSO
zmq_msg_copy(3) zmq_msg_init(3) zmq_msg_init_size(3) zmq_msg_init_data(3) zmq_msg_close(3) zmq(7) AUTHORS
