Description

       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 non-portable intimate knowledge of file system structures.

Name

       df - report file system space usage

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 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

       --no-sync
              do not invoke sync before getting usage info (default)

       --output[=FIELD_LIST]
              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

       --total
              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

       --version
              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 on.

       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 page).
