This distribution contains two modules Filesys::Statvfs
and Filesys::Df.

DESCRIPTION
Filesys::Statvfs provides an interface between
Perl and the statvfs() system call.

Filesys::Df uses Filesys::Statvfs to obtain
filesystem statistics then creates additional
filesystem information such as percent full,
user and superuser differentials, etc.

Filesys::Df will also let you specify the
block size for the values you wish to see.
The default block size output is 1024 bytes per
block. So if you want to get the size in bytes
just take the block size and * it by 1024.

SYNOPSIS Filesys::Statvfs

use Filesys::Statvfs;

	my($bsize, $frsize, $blocks, $bfree, $bavail,
        $files, $ffree, $favail, $fsid, $basetype, $flag,
        $namemax, $fstr) = statvfs("/tmp");


SYNOPSIS Filesys::Df

use Filesys::Df;

	my $ref = df("/tmp");  # Default block size of 1024 bytes.
	                       # You can specify a different block
                               # as a second argument.

	print"Percent Full:       $ref->{per}\n";
	print"Total Blocks:       $ref->{blocks}\n";
	print"Blocks Available:   $ref->{bavail}\n";
	print"Blocks Used:        $ref->{used}\n";
	print"Inode Percent full: $ref->{fper}\n";
	print"Inodes Free:        $ref->{favail}\n";
	print"Inodes Used:        $ref->{fused}\n";

	print"Total Bytes", ($ref->{blocks} * 1024), "\n";

	#These are just some of the keys that are available.
	#See the documentation for the others.



INSTALL
TO INSTALL RUN:
	
	perl Makefile.PL
	make
	make test
	make install

For this module to install and work properly you will need
to have the statvfs() system call on your system. A good way
to tell if you have it is to look for the sys/statvfs.h header
in your include directory. (Usually /usr/include/)

If there is an error during the 'make', it is
possible that you do not have statvfs() on your system.
Another possible reason may be that the statvfs structure defined
in statvfs.h does not contain one or more of the fields that are
defined in Statvfs.xs.

During the 'make test' test.pl will use statvfs()
to stat the root directory "/". If it fails it will
report an error, otherwise it will report all the 
standard fields in the statvfs structure. If you
are running any flavor of Digital Unix, or IRIX, the fstr value
may be NULL. The 'make test' will then proceed to test df().

Once installed, run 'perldoc Filesys::Statvfs' and
'perldoc Filesys::Df' for more information. 

This has been tested successfully on HP-UX 10x, IRIX 6.3,
Solaris 2.6, RH Linux 6.5, AIX 4.3 and some Digital Unix.

NOTE: the fsid field on Linux and AIX will be zeroed. It will
be like this until I have time to add support for their fsid type.
I doubt anyone out there will use the fsid field anyway. :-P

Also please note that if the paticualr OS you are using does not
support some of the values returned by Statvfs::statvfs() they
will be zeroed or NULLed depending on whether they are integers
or string values.


If you have any problems or questions please email
me at IGuthrie@aol.com with "Filesys Module" in
the subject line.
