Running a command when screen locks

Sep 30, 2017 · 1 min read · CRYPTOMINER FEDORA26 ·

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

 1dbus-monitor --session "type=signal,interface=org.gnome.ScreenSaver" |
 2 while read MSG; do
 3 LOCK_STAT=`echo $MSG | grep boolean | awk '{print $2}'`
 4   if [[ "$LOCK_STAT" == "true" ]]; then
 5    echo "was locked"
 6    killall myfile
 7    screen -d -m /pathto/myfile -flags
 8   else
 9    echo "was un-locked"
10    killall myfile
11   fi
12 done
