Tshark
Tshark is a command-line network protocol analyzer and packet capture tool, part of the Wireshark suite. It allows users to capture, display, and analyze network traffic in real-time or from saved capture files, using the same powerful dissection engine as Wireshark but without a graphical interface. It is commonly used for network troubleshooting, security analysis, and protocol development.
Developers should learn Tshark when they need to perform network analysis in headless environments, automate packet capture tasks, or integrate network monitoring into scripts and applications. It is particularly useful for debugging network protocols, analyzing security incidents, and monitoring network performance in server or cloud environments where a GUI is unavailable.
