Checking the Size of Directories

You can display the size of directories by using the du command and its options. Additionally, you can find the amount of disk space taken up by user accounts on local UFS file systems by using the quot command. For more information about these commands, see du(1M)and quot(1M).

How to Display the Size of Directories, Subdirectories, and Files

Display the size of one or more directories, subdirectories, and files by using the du command. Sizes are displayed in 512-byte blocks.

$ du [-as] [directory ...]
