    NAME

    df - report file system 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 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
    -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 1000*1000, M 1024*1024, and so on for G, T, P, E, Z, Y.
