       df - report file system space usage


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


       This manual page documents the GNU version of df.  df displays the amount
       of 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.  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 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.  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.


       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 pseudo, duplicate, inaccessible file systems

       -B, --block-size=SIZE
              scale sizes by SIZE before printing them; e.g., '-BM' prints sizes
              in units of 1,048,576 bytes; see SIZE format below

       -h, --human-readable
              print sizes in powers of 1024 (e.g., 1023M)

       -H, --si
              print sizes in powers of 1000 (e.g., 1.1G)

       -i, --inodes
              list inode information instead of block usage

       -k     like --block-size=1K

       -l, --local
              limit listing to local file systems

              do not invoke sync before getting usage info (default)

              use the output format defined by FIELD_LIST, or print all fields
              if FIELD_LIST is omitted.

       -P, --portability
              use the POSIX output format

       --sync invoke sync before getting usage info

              elide all entries insignificant to available space, and produce a
              grand total

       -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

       -v     (ignored)

       --help display this help and exit

              output version information and exit

       Display values are in units of the first available SIZE from
       --block-size, and the DF_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE environment
       variables.  Otherwise, units default to 1024 bytes (or 512 if
       POSIXLY_CORRECT is set).

       The SIZE argument is an integer and optional unit (example: 10K is
       10*1024).  Units are K,M,G,T,P,E,Z,Y,R,Q (powers of 1024) or KB,MB,...
       (powers of 1000).  Binary prefixes can be used, too: KiB=K, MiB=M, and so

       FIELD_LIST is a comma-separated list of columns to be included.  Valid
       field names are: 'source', 'fstype', 'itotal', 'iused', 'iavail',
       'ipcent', 'size', 'used', 'avail', 'pcent', 'file' and 'target' (see info
