The command "ykinfo -c" is likely referring to a command-line utility called "ykinfo" with the "-c" option. However, without additional context, it's difficult to provide an accurate explanation of what this specific command does.

In general, a command like "ykinfo" is often associated with YubiKey devices. YubiKey is a hardware authentication device that provides two-factor authentication and other security features. "ykinfo" is a tool used to retrieve information about the connected YubiKey devices.

The "-c" option is often used to display the YubiKey's configuration settings. So, "ykinfo -c" would request and display the configuration details of the connected YubiKey device. This may include information about the device's firmware version, supported protocols (such as OTP, U2F, etc.), enabled features, and other related details.
