NAME Filesys::DiskFree -- perform the Unix command 'df' in a portable fashion SYNOPSIS use Filesys::DiskFree; $handle = new Filesys::DiskFree; $handle->df(); print "The root device is ".$handle->device("/")."\n"; print "It has ".$handle->avail("/")." bytes available\n"; print "It has ".$handle->total("/")." bytes total\n"; print "It has ".$handle->used("/")." bytes used\n"; DESCRIPTION Filesys::DiskFree does about what the unix command df(1) does, listing the mounted disks, and the amount of free space used & available. Functions Filesys::DiskFree->set('option' => 'value') Sets various options within the module. The most common option to change is the mode, which can be either blocks or inodes. By default, blocks is used. If reading a file from a 'foreign' OS using the load() function, format may be used, which takes the name of an OS as set in the $^O variable. Returns the previous values of the options. Filesys::DiskFree->df() Perfoms a 'df' command, and stores the values for later use. Filesys::DiskFree->command() Returns the appropriate command to do a 'df' command, for the current format. This is used when you wish to call a df on a remote system. Use the df() method for local df's. Returns undef if there isn't an appropriate command. Filesys::DiskFree->load($line) Reads in the output of a 'df', $line can be either a scalar or a filehandle. If $line is a filehandle, then the filehandle is read until EOF. Returns undef on failure Filesys::DiskFree->disks() Returns all the disks known about Filesys::DiskFree->device($id) Returns the device for $id, which is a scalar containing the device name of a disk or a filename, in which case the disk that filename in stored upon is used. Filesys::DiskFree->mount($id) Returns the mount point for $id, which is a scalar containing the device name of a disk or a filename, in which case the disk that filename in stored upon is used. Filesys::DiskFree->avail($id) Returns the amount of available space in bytes for $id, which is a scalar containing the device name of a disk or a filename, in which case the disk that filename in stored upon is used. Filesys::DiskFree->total($id) Returns the amount of total space in bytes for $id, which is a scalar containing the device name of a disk or a filename, in which case the disk that filename in stored upon is used. Filesys::DiskFree->used($id) Returns the amount of used space in bytes for $id, which is a scalar containing the device name of a disk or a filename, in which case the disk that filename in stored upon is used. BUGS It should support more formats, currently only Linux, Irix, Solaris & BSD are supported. Other formats will be added as available. Please sent your OS Name & version, the 'best' df options to use, and the output of df with those options, and the contents of $^O if you have access to a non-supported format. AUTHOR Alan R. Barclay
