I am looking for a way to store lock/unlock screen times.
A=$(date)
echo $A >> $HOME/time_xprofile
What did I try:
$HOME/.bashrc
$HOME/.bash_logout
$HOME/.bash_prompt
$HOME/.xprofile
Then I locked the screen and checked whether file appeared and it failes every time. How can I check the time than?
The following script will write lock/unlock time in a file time_xprofile in your home.
#!/bin/bash
dbus-monitor --session "type='signal',interface='org.gnome.ScreenSaver'" |
( while true
do read X
if echo $X | grep "boolean true" &> /dev/null; then
echo "locking at $(date)" >> $HOME/time_xprofile
elif echo $X | grep "boolean false" &> /dev/null; then
echo "unlocking at $(date)" >> $HOME/time_xprofile
fi
done )
save the script. Give it execution permission.
chmod +x script.sh
How to run
./script.sh &
Note The script should run in back ground. Do not kill it. If you turn your screen lock/unlock while the script is running in background, your time of lock/unlock will be recorded in time_xprofile file at your home. One can use it to run some command or script at screen lock/unlock.
Mind that if you close the current terminal your script will be killed. You can use
nohup ./script.sh &
Then it will continue running even after closing the terminal.
How to kill the script
To kill the process, use in terminal
ps ax| grep "[s]cript.sh" | cut -d' ' -f2 | xargs kill
Above script is inspired by this answer
