du -h -d 2 /usr

Sorry, as an AI language model, I don't have the access to the file system of a specific system. However, I can explain the meaning of the command.

The command "du" stands for "disk usage" and is used to estimate the file space usage in a directory or file system. The options "-h" and "-d" are used to modify the output of the command. "-h" stands for "human-readable" and prints the sizes in a more readable format such as KB, MB, GB. "-d" stands for "depth" and specifies the maximum depth of the directory hierarchy to display.

Therefore, the command "du -h -d 2 /usr" will display the disk usage of the directory "/usr" and its immediate subdirectories up to a maximum depth of 2, with the sizes displayed in a human-readable format.
