DF(1)                       General Commands Manual                      DF(1)

NAME
       df - report on free disk space

SYNOPSIS
       df [-ikP] [-t type] [file ...]

DESCRIPTION
       Df  lists the amount of free space on the currently mounted devices (no
       arguments), or the devices given as arguments.  If the argument is  not
       a device then the device it resides on is listed.

OPTIONS
       Without options, df will give a listing like this:

       Filesystem    1k-Blocks     free     used    %  FUsed%  Mounted on
       /dev/c0d0p1s0      1440      635      805  56%    26%   /
       /dev/c0d0p1s1     32768    32390      378   2%     1%   /tmp
       /dev/c0d0p1s2    784657   517809   266848  35%    29%   /usr

       The -i option shifts the focus to the files:

       Filesystem        Files     free     used    %  BUsed%  Mounted on
       /dev/c0d0p1s0      1024      759      265  26%    56%   /
       /dev/c0d0p1s1      5472     5468        4   1%     2%   /tmp
       /dev/c0d0p1s2     65535    46734    18801  29%    35%   /usr

       Option -P makes df use POSIX defined output in 512 byte units:

       Filesystem     512-blocks    Used  Available  Capacity  Mounted on
       /dev/c0d0p1s0      2880      1628     1252       57%    /
       /dev/c0d0p1s1     65536       756    64780        2%    /tmp
       /dev/c0d0p1s2   1569314    533748  1035566       35%    /usr

       With -k 1024 byte units would be used.

       The -t option limits df's output to file systems of the given type.

FILES
       /etc/mtab      List of mounted file systems.

SEE ALSO

BUGS
       Default output should also be in 512 byte units says POSIX.
