comment How to check if NTPD updates machine's time successfully using shell?
@dvc The scripts there don't seem to include the requested functionality. There seems to be some code to generate SNMP traps, but I haven't encountered SNMP to monitor NTP. I've had to do my own monitoring in several large organizations.

@badcook ifconfig normally won't know if your public IP address is already taken. See my edit.

I am qualifying the answer. A plain wait will fail to provide the desired result. It is common to use the short forms as they are less prone to typos.

There are a number of short forms for entering the PID of the backgrounded process such as %, %1 and $!. It is important to supply the PID or the second command will always run.

Waiting on the command should do the job.

@slm return status on the backgrounded command will only be available if no other command is run in the background after it. The variable containing the return status is not $?.
