This command appears to be using the sudo command to execute the ledctl command with the locate option and a comma-separated value as the argument. Here's a breakdown of each component:

sudo: This is a command that allows a user to execute a command with superuser privileges. It prompts the user for their password before executing the subsequent command.
ledctl: This is the main command being executed. Without further context, it is difficult to determine the exact purpose or functionality of this command.
locate=${-dev-sda,-dev-sdb,---}: This is the argument given to the ledctl command using the locate option. It consists of a string that represents a comma-separated list of values. Each value starts with a -dev- prefix followed by some alphanumeric characters (e.g., sda, sdb, etc.). The final value appears to be a placeholder represented by three dashes (---).

Without additional information about the ledctl command or the purpose of the locate option, it is challenging to provide an accurate explanation of what this command achieves.
