## 4.3. Start Capturing

The following methods can be used to start capturing packets with Wireshark:

- You can double-click on an interface in the welcome screen.
- You can select an interface in the welcome screen, then select Capture → Start or click the first toolbar button.
- You can get more detailed information about available interfaces using Section 4.5, “The “Capture Options” Dialog Box” (Capture → Options…​).
- If you already know the name of the capture interface you can start Wireshark from the command line:

    $ wireshark -i eth0 -k

This will start Wireshark capturing on interface `eth0`. More details can be found at Section 11.2, “Start Wireshark from the command line”.
