NAME

       df - report filesystem disk space usage

SYNOPSIS

       df [OPTION]... [FILE]...

DESCRIPTION

       This  manual  page  documents the GNU version of df.  df displays the amount of disk space available on the filesystem containing each file
       name argument.  If no file name is given, the space available on all currently mounted filesystems 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 filesystem, df shows the space available on that
       filesystem rather than on the filesystem containing the device node (which is always the root filesystem).  This version of df cannot  show
       the  space  available  on  unmounted filesystems, because on most kinds of systems doing so requires very nonportable intimate knowledge of
       filesystem structures.

OPTIONS

       Show information about the filesystem on which each FILE resides, or all filesystems by default.

       Mandatory arguments to long options are mandatory for short options too.

       -a, --all
	      include filesystems having 0 blocks

       -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 filesystems

       --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 filesystems of type TYPE

       -T, --print-type
	      print filesystem type

       -x, --exclude-type=TYPE
	      limit listing to filesystems not of type TYPE

       -v     (ignored)

       --help display this help and exit

       --version
	      output version information and exit

       SIZE 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.

NAME

       du - estimate file space usage

SYNOPSIS

       du [OPTION]... [FILE]...

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

       SIZE 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.

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).
