Bash based dead man switch

Dead Mans Switch

A dead man's switch is a switch that is designed to be activated or deactivated if the human operator becomes incapacitated, such as through death, loss of consciousness, or being bodily removed from control.

What it does

In the event you are unable to get access to your system for a certain period of days this script will automatically run any scripts you have provided.

Setup

Download the script and put it into its own directory. Afterwords put a scripts directory inside of it and add your scripts into it. Naming scheme must be DMS-NAMEHERE.sh

Be sure to edit the script and change the userName, inactiveDays, and shouldWait options.

Structure

└── DMS/
    ├── dms.sh
    └── scripts/
        └── DMS-testscript.sh

Possible issues

• If the user that is listed in the script doesn't have journalctl access we will fall back to using lastlog instead
• May not be compatible with non-systemd systems (Aslong as your system has lastlog it should be good)
