du − summarize disk usage
du [ −s ] [ −a ] [ name ... ]
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.
Non-directories
given as arguments (not under −a option) are
not listed.
If there are too many distinct linked files, du
counts the excess files multiply.
