DF(1)                                SysV                                DF(1)



NAME
     df - report number of free disk blocks and i-nodes

SYNOPSIS
     df [-atfF nodefile] [file-system | file | directory | 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 or directory is contained, or on the node specified by
     node_spec (either //nodename or [net.]nodeid).

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

     The device filename returned by df is defined as follows:

     <controller type><controller number>d<drive number>s<logical volume>

     Where:

     <controller type> is the symbol for the device type and should be a 'W'
     for winchester, an 'F' for floppy, or an 'S' for storage module.

     <controller number> is a number between '0' and '6' inclusive, defining
     which controller is to be used with this device.

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

     <logical volume> is a hexadecimal number between '1' and 'f' inclusive,
     defining the logical volume number.

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

     -t   Causes the figures for total allocated blocks and i-nodes to be
          reported as well as the free blocks and i-nodes.

     -f   Takes an actual count of the blocks in the free list, rather than
          taking the figure from the super-block (free i-nodes are not
          reported).  This option does not print any information about mounted
          remote resources.

     -F nodefile
          nodefile contains information describing nodes for which df will
          print information.  This file should contain lines of the form:

          //nodename

          or

          [net.]nodeid

          There may only be one node identifier per line.  A pound sign (#) 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
     /dev/dsk/*

     /etc/mnttab
