 +# mintupdate-on-wakeup by tux@enkidu.eu
 +#
 +# (based on unattended-upgrades-alternative 1.1 by tux@enkidu.eu)
 +#
 +# 28.12.2018: v1.0 - initial release (Mint 18 only)
 +# 30.04.2021: v2.0 - added support for mintupdate-cli
 +#
 +################################################################################
 +AUTHOR="tux@enkidu.eu"; VER=2.0

 +#
 +# This is a simple replacement for "unattended-upgrades".
 +# It is NOT thought for server usage!
 +# It is thought for e.g. users with a notebook, where normal usage is
 +#   open notebook = resume/wakeup
 +#  close notebook = hibernate/suspend
 +#
 +# Script is executed after each wakeup and update done 2-3 times a day.
 +# (Not at every resume, only if first digit of 2 digit hour changes.
 +#  E.g. 0x (00, 01, 02, ...),  1x, 2x)

 +# Installation:
 +# -------------
 +#
 +# Place this script in $HOME/bin

 +# > chmod 755 $HOME/bin/mintupdate-on-wakeup
 +# > sudo ln -s $HOME/bin/mintupdate-on-wakeup /lib/systemd/system-sleep/
 +#
 +#
 +# If you want to check for updates after login, you have to add
 +#
 +#   sudo $HOME/bin/mintupdate-on-wakeup login
 +#
 +# to your
 +#
 +#   $HOME/.profile
