для B.11.31
 
#!/bin/sh
port=$1
for pid in `UNIX95=1 ps -ef -o pid | tail +2`

           ./port.sh 7001
           proc: 9575,     localaddr/port = 0.0.0.0/7001 (listening)
 
 
как обойтись только системными утилитами в B.11.23 я не знаю, можно использовать lsof как и в linux,
скачать losf для HP-UX можно здесь
