# 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.
