This command is likely used in a Linux or Unix command line interface. Let's break it down:

• "pinky" is a command-line utility in Unix-like operating systems that retrieves and displays information about users on the system.
• "${user}" is a placeholder variable that represents the username or user account you want to query with the "pinky" command.
• "-lb" are options or flags that modify the behavior of the "pinky" command. The specific meaning of these options may vary depending on the implementation of the "pinky" command, as different versions or distributions might have slightly different features.

In summary, this command is used to gather information about a specific user (represented by "${user}") using the "pinky" utility. The "-lb" options further define the details of the output. To fully understand how the "-lb" options affect the command, you would need to refer to the documentation for the specific version or distribution of the "pinky" command you are using.
