In one of my previous blog entry I have presented a start script, but this was not my favourite. I have changed into a shutdown script because I think it is more useful. After a reboot or shutdown, you have en empty free home directory from PDF files.

I directly save the PDF files into the home directory $Home.

The new thing is the system will ask you whether you want to reboot or shutdown the system. If you don’t enter r for reboot or s for shutdown, then the script will terminate.

It could use if you only want to move and delete the files.

#!/bin/bash

#current date
datum=$(date --utc --date "$1" +%x)

#when the pc was turned on
einschaltuhrzeit=$(uptime -s | awk '{print $2}')


#message for the user
echo "Today is $datum. The pc was turned on at $einschaltuhrzeit "


#counting the day until finish of the current year
restlichentage=$(((`date +%s`-`date -d "Dec 31 2025" +%s`+1)/86400))

echo "To the end of the year are $restlichentage days"
