NAME [Toc] [Back]
du - summarize disk usage
SYNOPSIS [Toc] [Back]
du [-a|-s] [-bkrx] [-t type] [name ...]
DESCRIPTION [Toc] [Back]
The du command gives the number of 512-byte blocks allocated for all
files and (recursively) directories within each directory and file
specified by the name operands. The block count includes the indirect
blocks of the file. A file with two or more links is counted only
once. If name is missing, the current working directory is used.
By default, du generates an entry only for the name operands and each
directory contained within those hierarchies.
Options [Toc] [Back]
The du command recognizes the following options:
-a Print entries for each file encountered in the
directory hierarchies in addition to the normal
-b For each name operand that is a directory for
which file system swap has been enabled, print the
number of blocks the swap system is currently
-k Gives the block count in 1024-byte blocks.
-r Print messages about directories that cannot be
read, files that cannot be accessed, etc. du is
normally silent about such conditions.
-s Print only the grand total of disk usage for each
of the specified name operands.
-x Restrict reporting to only those files that have
the same device as the file specified by the name
operand. Disk usage is normally reported for the
entire directory hierarchy below each of the given
-t type Restrict reporting to file systems of the
specified type. (Example values for type are hfs,
cdfs, nfs, etc.) Multiple -t type options can be
specified. Disk usage is normally reported for
the entire directory hierarchy below each of the
given name operands.
