Full, or even nearly full, directories and partitions can cause a system to slow down, prevent users from logging in and even result in a system crash. Thus, a typical computer contains a large number of directory trees.ĭu is commonly employed by system administrators as a supplement to automated monitoring and notification programs that help prevent key directories and partitions (i.e., logically independent sections of a HDD) from becoming full. Any directory can be regarded as being the start of its own directory tree, at least if it contains subdirectories. This makes it useful for tracking down space hogs, i.e., directories and files that consume large or excessive amounts of space on a hard disk drive (HDD) or other storage media.Ī directory tree is a hierarchy of directories that consists of a single directory, called the parent directory or top level directory, and all levels of its subdirectories (i.e., directories within a directory). The du (i.e., disk usage) command reports the sizes of directory trees inclusive of all of their contents and the sizes of individual files.
