SYNOPSIS

       df [-F fstype] [-M mtab] [-o fsoptions] [-befghiklnPtv] [file ...]
       dfspace [-F fstype] [file ...]

DESCRIPTION

       Df  prints file system statistics.  A file system is selected by a file
       it contains, or by its device file, as specified by the file  argument.
       If  no  file  argument is given, statistics are printed for all mounted
       file systems.  The basic size unit is a block consisting of 512  bytes.

       dfspace prints available and total disk space in megabyte units.

       The df command accepts the following options:

       -b     Print only the number of kilobytes free.

       -be    Print counts of free kilobytes and available files.

       -e     Print only the number of available files.

       -f     Omit the number of available files in traditional output format.

       -F fstype
              Restrict output to filesystems of type fstype.

       -g     Print the entire statvfs(2) structure.  Overrides  the  -b,  -e,
              -k, -n, -P, and -t options.

       -k     If  given  alone,  the  allocation  is  printed in kbytes, and a
              different output format  is  used.   If  combined  with  the  -P
              option,  the  size  unit  is  changed  from  blocks  to  kbytes.
              Overrides the -b, -e, -f, -n, -t, and -v options.

       -l     Omit statistics about non-local file systems.   Currently,  file
              systems  with  types  of nfs and smbfs are considered to be non-
              local.

       -n     Print the file system mount point and file system type only.

       -o fsoptions
              Specifiy file-system specific options.  There are none  so  this
              option will always cause an error message.

       -t     Use  the  traditional  output  format  as it is the default, but
              include total allocated-space figures in the output.   Overrides
              the -b, -e and -n options.

       -v     Select  verbose  output  format,  that  is, mount point, device;
              total, used, and free block counts; and usage in percent.

       -V     Print command lines for each file system only.

              filesystems.

FILES

       /etc/mtab
              default mount table

ENVIRONMENT VARIABLES

       SYSV3  If  this  variable is set, the output text `files' is changed to
              `i-nodes'.

SEE ALSO

       find(1), statvfs(2), mtab(5), mount(8)

NOTES

       This df implementation cannot handle unmounted file systems.

       Some advanced file system designs  allocate  i-nodes  dynamically.   Df
       then  tries to estimate free and total counts of available files.  This
       is currently done for the reiserfs file system.
