[\fIFILE\fR]....SH DESCRIPTION.\" Add any additional description here.PPSummarize disk usage of each FILE, recursively for directories..PPMandatory arguments to long options are mandatory for short options too..TP\fB\-a\fR, \fB\-\-all\fRwrite counts for all files, not just directories.HP\fB\-B\fR, \fB\-\-block\-size\fR=\fISIZE\fR use SIZE-byte blocks.TP\fB\-b\fR, \fB\-\-bytes\fRprint size in bytes.TP\fB\-c\fR, \fB\-\-total\fRproduce a grand total.TP\fB\-D\fR, \fB\-\-dereference\-args\fRdereference PATHs when symbolic link.TP\fB\-h\fR, \fB\-\-human\-readable\fRprint sizes in human readable format (e.g., 1K 234M 2G).TP\fB\-H\fR, \fB\-\-si\fRlikewise, but use powers of 1000 not 1024.TP\fB\-k\fRlike \fB\-\-block\-size\fR=\fI1K\fR.TP\fB\-l\fR, \fB\-\-count\-links\fRcount sizes many times if hard linked.TP\fB\-L\fR, \fB\-\-dereference\fRdereference all symbolic links.TP\fB\-S\fR, \fB\-\-separate\-dirs\fRdo not include size of subdirectories.TP\fB\-s\fR, \fB\-\-summarize\fRdisplay only a total for each argument.TP\fB\-x\fR, \fB\-\-one\-file\-system\fRskip directories on different filesystems.TP\fB\-X\fR FILE, \fB\-\-exclude\-from\fR=\fIFILE\fRExclude files that match any pattern in FILE..HP\fB\-\-exclude\fR=\fIPATTERN\fR Exclude files that match PATTERN..TP\fB\-\-max\-depth\fR=\fIN\fRprint the total for a directory (or file, with \fB\-\-all\fR)only if it is N or fewer levels below the commandline argument;  \fB\-\-max\-depth\fR=\fI0\fR is the same as\fB\-\-summarize\fR.TP\fB\-\-help\fRdisplay this help and exit.TP\fB\-\-version\fRoutput version information and exit.PPSIZE may be (or may be an integer optionally followed by) one of following:kB 1000, K 1024, MB 1,000,000, M 1,048,576, and so on for G, T, P, E, Z, Y..SH PATTERNSPATTERN is a shell pattern (not a regular expression).  The pattern.BR ?matches any one character, whereas.BR *matches any string (composed of zero, one or multiple characters).  Forexample,.BR *.owill match any files whose names end in.BR .o .Therefore, the command.IP.B du --exclude='*.o'.PPwill skip all files and subdirectories ending in.BR .o(including the file.BR .oitself)..SH AUTHORWritten by Torbjorn Granlund, David MacKenzie, Larry McVoy, and Paul Eggert..SH "REPORTING BUGS"Report bugs to <bug-fileutils@gnu.org>..SH COPYRIGHTCopyright \(co 2002 Free Software Foundation, Inc..brThis is free software; see the source for copying conditions.
