The command "tshark -T ${select} -e ${http-request-method} -e ${ip-src}" is used to capture network traffic and display specific information about HTTP request methods and source IP addresses.

Here's a breakdown of each component of the command:

• "tshark": Tshark is a command-line packet analyzer tool used for capturing and analyzing network packets.
• "-T ${select}": The "-T" option specifies the output format of the captured packets. In this case, "${select}" is a placeholder for a specific output format chosen by the user. It could be options like json, pdml (Packet Details Markup Language), psml (Packet Summary Markup Language), etc.
• "-e ${http-request-method}": The "-e" option is used to specify the specific field or field name to display in the output. In this case, "${http-request-method}" is a placeholder for the HTTP request method field. It will display the method used in the HTTP request sent by the client, such as GET, POST, PUT, etc.
• "-e ${ip-src}": Similar to the previous option, "${ip-src}" is a placeholder for the source IP field. It will display the IP address of the sender/source of the captured packets.

So, when you execute this command, Tshark will capture network packets and output the selected format specified by "${select}". The output will include the HTTP request method and the source IP address for each captured packet.
