 DF(1)                          FSF                          DF(1)
 
 
 
NAME
        df - report filesystem disk space usage
 
SYNOPSIS
        df [OPTION]... [FILE]...
 
DESCRIPTION
        This manual page documents the GNU version of df.  df dis­
        plays 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.
 
        -a, --all
               include filesystems having 0 blocks
 
        --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, --kilobytes
               like --block-size=1024
 
        -l, --local
               limit listing to local filesystems
 
        -m, --megabytes
               like --block-size=1048576
 
        --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
