DF(1)                                BSD                                 DF(1)



NAME
     df - disk free

SYNOPSIS
     df [ -iaF nodefile ] [ filesystem | file | node_spec ] ...

DESCRIPTION
     df prints the amount of free disk space available on the specified
     filesystem (for example, /dev/rp0a), on the filesystem in which the
     specified file is contained, node specified by node_spec (either
     //nodename or [net.]nodeid).

     If you don't specify a file system, df prints the free space for all
     normally mounted file systems.  The reported numbers are in kilobytes.

     The device filename returned by df is defined as follows:
          <ctype><cnum + 16 + dnum><logvol>

     Where:

     ctype
          is the symbol for the device controller type and can be wn for
          winchester, fl for floppy, or sm for storage module.

     cnum is a number between 0 and 6 inclusive, defining which controller is
          used with this device.

     dnum is a number between 0 and 7 inclusive, defining the drive on which
          the controller resides.

     logvol
          is a character between a and o, with a the first logical device and
          o the fifteenth.

OPTIONS
     -i   Report the number of inodes that are used and free.  This option has
          no meaning on Domain/OS file systems, since there is no limit.

     -a   Print the values of total disk space, space available, space used,
          and percentage of disk space used.

          If none of [ filesystem | file | node_spec ] are specified, df will
          report on status for all nodes in the network.

     -F nodefile
          nodefile contains information describing nodes for which df will
          print information.  This file should contain node specifications
          (see node_spec(5)).  There may only be one node_spec per line.  A
          `#' in the first column of a line in the file causes that line to be
          treated as a comment.

NOTES
     If multiple remote resources are listed that reside on the same file
     system on a remote machine, each listing after the first one is marked
     with an asterisk (*).

     df will not report status information for NFS or CDROM filesystems that
     are mounted on remote machines.

     df lists the free space on all volumes in /etc/mnttab.  If a volume is
     listed twice in the mount table, df will also list it twice.  If a

     mounted volume is not listed in /etc/mnttab, the volume will not show up
     in a df list.

WARNING
     The device filename printed might not exist if the mount command is not
     used to mount the volume.

FILES
     /etc/mnttab    List of normally mounted filesystems
