df - Speicherplatznutzung des Dateisystems melden ( man )
df [OPTION]... [FILE]...
Description
This manual page documents the GNU version of df. df displays the amount of disk space available on the file system containing each file name argument. If no file name is given, the space available on all currently mounted file systems is shown. Disk space is shown in 1K blocks by default, unless the environment variable POSIXLY_CORRECT is set, in which case 512-byte blocks are used.
If an argument is the absolute file name of a disk device node containing a mounted file system, df shows the space available on that file system rather than on the file system containing the device node (which is always the root file system). This version of df cannot show the space available on unmounted file systems, because on most kinds of systems doing so requires very nonportable intimate knowledge of file system structures.
Options
Show information about the file system on which each FILE resides, or all file systems by default.
Mandatory arguments to long options are mandatory for short options too.
-a, --all
include dummy file systems
-B, --block-size=SIZE use SIZE-byte blocks
-h, --human-readable
print sizes in human readable format (e.g., 1K 234M 2G)
-H, --si
likewise, but use powers of 1000 not 1024
-i, --inodes
list inode information instead of block usage
-k
like --block-size=1K
-l, --local
limit listing to local file systems
--no-sync
do not invoke sync before getting usage info (default)
-P, --portability
use the POSIX output format
--sync
invoke sync before getting usage info
-t, --type=TYPE
limit listing to file systems of type TYPE
-T, --print-type
print file system type
-x, --exclude-type=TYPE
limit listing to file systems not of type TYPE
du - Schätzung des Speicherplatzbedarfs ( man )
du [OPTION]... [FILE]...
du [OPTION]... --files0-from=F
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
--apparent-size
print apparent sizes, rather than disk usage; although the apparent size is usually smaller, it may be larger due to holes in ('sparse') files, internal fragmentation, indirect blocks, and the like
-B, --block-size=SIZE use SIZE-byte blocks
-b, --bytes
equivalent to '--apparent-size --block-size=1'
-c, --total
produce a grand total
-D, --dereference-args
dereference FILEs that are symbolic links
--files0-from=F
summarize disk usage of the NUL-terminated file names specified in file F
-H
like --si, but also evokes a warning; will soon change to be equivalent to --dereference-args (-D)
-h, --human-readable
print sizes in human readable format (e.g., 1K 234M 2G)
--si
like -h, but use powers of 1000 not 1024
-k
like --block-size=1K
-l, --count-links
count sizes many times if hard linked
-m
like --block-size=1M
-L, --dereference
dereference all symbolic links
-P, --no-dereference
don't follow any symbolic links (this is the default)
-0, --null
end each output line with 0 byte rather than newline
-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 file systems
-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
--time
show time of the last modification of any file in the directory, or any of its subdirectories
--time=WORD
show time as WORD instead of modification time: atime, access, use, ctime or status
--time-style=STYLE show times using style STYLE:
full-iso, long-iso, iso, +FORMAT FORMAT is interpreted like 'date'
