Sorry if this is a really dumb question but the documentation I've found on this subject is a bit sketchy and or beyond my experience. I want to replicate the UNIX (spit) df -k command so that I can monitor the utilisation of certain disc slices. After a bit of investigation I settled on the Filesys::DiskFree module. The problem is I can't get anything out of this script. I would have expected the following code to return a list of disc slices on the supplied disc name -

#!/usr/bin/perl -w
#
use Filesys::DiskFree;
#
$disc = '/dev/vx/dsk/var' ;

new Filesys::DiskFree ;

$handle->avail($disc) ;

[download]

I get the error message - Can't call method "avail" on an undefined value. Am I being particularily stupid here? Where do the returned values (if any - and there should be about 12) go to? I'm not very familiar with modules/methods so I won't be offended if this request is treated with disdain as long as my understanding of it improves.

Cheers,the ever so humble Ronnie Cruickshank
