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.
