Linux / Unix Command: du |
NAME
du - estimate file space usageSYNOPSIS
du [OPTION]... [FILE]...EXAMPLES
DESCRIPTION
Summarize disk usage of each FILE, recursively for directories.
Mandatory arguments to long options are mandatory for short options too.
- -a, --all
- write counts for all files, not just directories
- -B, --block-size=SIZE use SIZE-byte blocks
- -b, --bytes
- print size in bytes
- -c, --total
- produce a grand total
- -D, --dereference-args
- dereference FILEs that are symbolic links
- -h, --human-readable
- print sizes in human readable format (e.g., 1K 234M 2G)
- -H, --si
- likewise, but use powers of 1000 not 1024
- -k
- like --block-size=1K
- -l, --count-links
- count sizes many times if hard linked
- -L, --dereference
- dereference all symbolic links
- -S, --separate-dirs
- do not include size of subdirectories
- -s, --summarize
- display only a total for each argument
- -x, --one-file-system
- skip directories on different filesystems
- -X FILE, --exclude-from=FILE
- Exclude files that match any pattern in FILE.
- --exclude=PATTERN Exclude files that match PATTERN.
- --max-depth=N
- print the total for a directory (or file, with --all) only if it is N or fewer levels below the command line argument; --max-depth=0 is the same as --summarize
- --help
- display this help and exit
- --version
- output version information and exit
PATTERNS
PATTERN is a shell pattern (not a regular expression). The pattern ? matches any one character, whereas * matches any string (composed of zero, one or multiple characters). For example, *.o will match any files whose names end in .o. Therefore, the command- du --exclude='*.o'
will skip all files and subdirectories ending in .o (including the file .o itself).
SEE ALSO
The full documentation for du is maintained as a Texinfo manual. If the info and du programs are properly installed at your site, the command- info du
should give you access to the complete manual.
