I use this to fire off a cryptominer when my screen locks. Works on Fedora 26
I run this command as a batch file in screen. Could be made into a daemon i suppose but screen works good enough for now

dbus-monitor --session "type=signal,interface=org.gnome.ScreenSaver" |
while read MSG; do
 LOCK_STAT=`echo $MSG | grep boolean | awk '{print $2}'`
   if [[ "$LOCK_STAT" == "true" ]]; then
    echo "was locked"
    killall myfile
    screen -d -m /pathto/myfile -flags
   else
    echo "was un-locked"
    killall myfile
   fi
done

This command will tar an entire folder, pass it to gzip then pass it to SSH which then in turn writes the resultant output to a file on a remote server
Useful for backing up small folders to remote servers
Dont forget to ssh-copy-id on the source server so password-less authentications works

tar -cvf - /var/log/httpd/ | /bin/gzip -c | /usr/bin/ssh root@1.1.1.1 'cat > /root/test.tar.gz'
