DF(1M) SysV DF(1M)
NAME
df - report number of free disk blocks and i-nodes
SYNOPSIS
df [-atfF nodefile] [file-system | 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 is contained, or on the specified node, nodename.
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 is defined as follows:
<ctype><cnum>d<dnum>s<logvol>
Where:
ctype
is the symbol for the device controller type and should be a W for
winchester, an F for floppy, or an S for storage module.
cnum is a number between 0 and 3 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 hexidecimal 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 node specifications
(see node_spec(7)). 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.
NOTE
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 (*).
WARNING
The device filename printed might not exist if the mount command is not
used to mount the volume.
