tshark:tldr:ef8ef

The command "tshark -w ${filename}" is used to capture network traffic and save it into a file.

Here's a breakdown of the components of this command:

• "tshark" is a command-line network protocol analyzer tool that captures and analyzes live network traffic.
• "-w" is an option used to specify the output file where the captured traffic will be saved.
• "${filename}" is a placeholder indicating that a specific name for the output file should be provided. It can be replaced with an actual filename.

By executing this command, tshark will start capturing network traffic and save it into the specified file, allowing further analysis or playback of the captured traffic.
