11/3/71 DU (I) NAME du -- summarize disk usage SYNOPSIS du [--s] [--a] [name...] DESCRIPTION du gives the number of blocks contained in all files and (recursively) directories within each specified directory or file name. If name is missing, "." is used. The optional argument --s causes only the grand total to be given. The optional argument --a causes an entry to be generated for each file. Absence of either causes an entry to be generated for each directory only. A file which has two links to it is only counted once. FILES / SEE ALSO DIAGNOSTICS BUGS Files at the top level (not under --a option) are not listed. Removable file systems do not work correctly since i-- numbers may be repeated while the corresponding files are distinct. Du should maintain an i--number list per root directory encountered.
