.SH DESCRIPTION
.I Du
gives the number of Kbytes allocated to data blocks
of named
.I files
and, recursively, of files in named directories.
It assumes storage is quantized in units of 1024 bytes (Kbytes) by default. 
Other values can be set by the
.B -b
option;
.I size
is the number of bytes, optionally suffixed
.B k
to specify multiplication by 1024.
If
.I file
is missing,
the current directory is used.
The count for a directory includes the counts of the
contained files and directories.
.PP
The
.B -a
option prints the number of blocks
for every file in a directory.
Normally counts are printed only for contained directories.
.PP
The
.B -f
option ignores errors,
otherwise it stops on the first error.
.PP
The
.B -n
option prints the size in bytes and the name of each file; it sets
.BR -a .
.PP
The
.B -t
option prints, in the format of
.B du
.BR -n ,
the modified time of
each file rather than the size.
If the options
.B -tu
are specified then the accessed time is printed.
.PP
The
.B -q
option prints, in the format of
.B du
.BR -n ,
the QID of
each file rather than the size.
.PP
Finally, the
.B -s
option causes
.I du
to descend the hierarchy as always, but to print only a summary line
for each
.IR file .
