The command "ykman ${select} info" is a command that utilizes the ykman tool with a variable called ${select} passed as an argument to retrieve information about a YubiKey device.

Here's a breakdown of the command:

• "ykman": It refers to the executable or command-line tool named ykman.
• "${select}": It represents a variable that should be substituted with a specific value when running the command. The value of ${select} might determine which YubiKey device or operation the command applies to.
• "info": It is a subcommand provided by ykman, used to display information about a YubiKey device. It typically provides details about the device's firmware version, serial number, supported features, and other relevant information.

When executing this command, the specific value of ${select} should be replaced with the desired YubiKey device or operation identifier to get information about that particular device or operation.
