Output pending apt updates as a string and do something with it, good for crons. Aptitude based version of
# count package updates by the number of lines
# - just-print bypasses the sudo lock requirement
# - have to narrow it down to lines with brackets to avoid simulation warning that has whitespace at the start
# also note this will include any packages on hold, you should use apt pinning to hide them from the update process
UPDATES_COUNT=$(apt-get --just-print -V -u upgrade --assume-no | grep "(" | grep "^\s" | wc -l)
# store the hostname for later

# note that this will include packages pending replacement because of needing system reboot
UPDATES_COUNT=$(yum check-update --quiet | grep -v "^$" | wc -l)
# count security updates with a substring
