still-alive
prove the world you're still alive
usage
copy the html <still-alive>still alive</still-alive>
onto your website wherever you want the still-alive message to be shown.
then, change the variables in still-alive.sh as described in the first two
comments of the script.
to install, make still-alive.sh executable with chmod +x and copy or symlink it into
your desired bin directory, e.g. mv still-alive.sh ~/.local/bin/still-alive
if you find yourself being alive one day and want to show the world, run
still-alive without any arguments
which will update the still-alive message to the current ISO 8601 date :)
