du Command du
Summarize disk usage
du [-a] [-s] [directory ...]
du prints the total number of disk blocks used by each named
directory. If no directory is specified, du prints the disk
usage of the current directory.
The -a (all) option causes du to print a line for every file and
directory in the substructure. Normally it prints a line only
for each directory.
The -s (summary) option prints only the line for the top level
directory.
du understands links; it adds a file with more than one link to
it into the total only once.

commands, df, find
***** Notes *****
du does not count file-system overhead such as indirect blocks,
so occasionally a directory does not fit on a file system which
appears to contain enough room for it.
