The command "airport sniff ${1}" is used to capture or sniff the wireless network traffic on a specific network interface using Apple's airport utility.

Here is a breakdown of the components:

• "airport" refers to the airport utility command-line tool on macOS.
• "sniff" is the specific command within airport that allows you to capture network traffic.
• "${1}" is a placeholder or variable that represents the first argument passed to the script or command. It is typically used when performing command-line scripting and allows for flexibility by accepting different inputs.

In this specific command, the variable "${1}" is expected to be replaced with the name of the wireless network interface you want to sniff or capture the traffic from. For example, it could be something like "en0" or "en1" depending on your network setup.

So, when you run the command "airport sniff ${1}", it will initiate the airport utility and start sniffing or capturing network traffic on the specified wireless network interface.
