DU(1) DU(1) 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 gen- erated 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. BUGS 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.
