# Description: Disk usage for BSD Unix systems

our $VERSION = '1.3';

# BSD disks module for sysinfo client

# Author: R. W. Rodolico

# Date:  2017-11-24

# gets information on disks. Returns them as a hash

# uses standard df -kT and parses the output

# skips anything that does not have a device with /dev in it

# assumes the structure of the output is:

# device fstype size usedSpace availableSpace percentSpace mountPoint

# however, the output can sometimes wrap to multi lines, especially if the 

# device is long. So, we will replace all newlines with spaces, then 

# remove space duplications, then split on spaces and process each item in

# turn.

# NOTE: this will totally break if you have spaces in your mount point

#

# v1.3 20180424 RWR

# Fixed bug when diskinfo generates an error. Will still send error

# to STDERR, but will not break program.
