How to identify if a port is open on IBM i through qshell?

[rishabkaushik]

I have a bash script that checks if a port is open on IBM i, if it is then do nothing. If it is not then run a .war file for a java application.
I tried to find a qshell command like netstat or ss but they do not exist on IBM i. So I figured I can use curl to look for status as below.

curl --silent --max-time 3 localhost:$PORT >/dev/null

There is qsys2.netstat_info as well but I will prefer a shell command. Is there any such command that exist for IBM i?

Apologies for asking so many questions here.
