NAME
     df (generic) - report number of free disk blocks and files

SYNOPSIS
     df   [-F   FSType]   [-begklntV]    [current_options]    [-o
     specific_options] [directory | special | resource...]

DESCRIPTION
     df prints the allocation portions of the generic  superblock
     for  mounted  or  unmounted  file  systems,  directories  or
     mounted resources.  directory represents a  valid  directory
     name.   If  directory  is specified df reports on the device
     that contains the directory.  special represents  a  special
     device  (e.g.,  /dev/dsk/c1d0s8).   resource  is  an RFS/NFS
     resource name.  If arguments to df are  pathnames,  df  pro-
     duces a report on the file system containing the named file.

     current_options are options  supported  by  the  s5-specific
     module  of  df.   Other  FSTypes  do not necessarily support
     these options.  specific_options indicate suboptions  speci-
     fied   in   a  comma-separated  list  of  suboptions  and/or
     keyword-attribute pairs for interpretation  by  the  FSType-
     specific module of the command.

     The options are:

     -F        Specify the FSType on which to operate.   This  is
               only  needed if the file system is unmounted.  The
               FSType should be specified here or be determinable
               from /etc/vfstab by matching the mount_point, spe-
               cial, or resource with an entry in the table.

     -b        Print only the number of kilobytes free.

     -e        Print only the number of files free.

     -g        Print the entire statvfs structure.  Used only for
               mounted  file  systems.   Can  not  be  used  with
               current_options  or  with  the  -o  option.   This
               option  will  override  the -b, -e, -k, -n, and -t
               options.

     -k        Print allocation in kilobytes. This option  should
               be  invoked by itself because its output format is
               different from that of the other options.

     -l        Report on local file systems only.  Used only  for
               mounted  file  systems.   Can  not  be  used  with
               current_options or with the -o option.

     -n        Print only the FSType name.  Invoked with no argu-
               ments  this  option  prints a list of mounted file

               system types.  Used only for mounted file systems.
               Can  not  be used with current_options or with the
               -o option.

     -t        Print full listings with totals.  This option will
               override the -b, -e, and -n options.

     -V        Echo the complete command line, but do not execute
               the  command.   The  command  line is generated by
               using the options and arguments  provided  by  the
               user  and  adding to them information derived from
               /etc/mnttab or /etc/vfstab.  This option should be
               used to verify and validate the command line.

     -o        Specify FSType-specific options.

     If no arguments or options are specified, the free space  on
     all local and remotely mounted file systems is printed.

NOTES
     The -F option is intended for use with unmounted  file  sys-
     tems. This command may not be supported for all FSTypes.

FILES
     /dev/dsk/*
     /etc/mnttab    mount table
     /etc/vfstab    list of default parameters for each file sys-
     tem
