# mail: Sun Enterprise Server check - BB external script test
#
# version 1.0
# version 1.1 - properly uses $CAT instead of cat
# version 1.2 - properly uses $MACHINE instead of `uname -n` in bb-hosts check
# version 1.3 - properly uses $THIS_HOST instead of $MACHINE due to fqdn using comma in name - thanks Craig Cook
# version 1.4 - updated the "bad words" list 
# version 1.5 - updated the "bad words" to do does case insensitive now
# version 1.6 - updated the "bad words" to do exclude for "transferred", which had matched "err"
# version 1.7 - updated the "bad words" to do exclude for "hour.errlog", which had matched "err"
# version 1.8 - updated the "bad words" to do exclude for "day.errlog", which had matched "err"
