You could change this line ps aux | grep cinnamon-session | grep -v grep to this pgrep cinnamon-session It's cleaner and works well. To answer the main question, try to install bashdb and run the script thru it. It's the bash debugger, it's far more powerful than bash -vx.

I recently installed kde5 on debian stretch. I have a yubikey which I use to log in with. I'd like to lock the screen when I remove the yubikey. I have it working with cinnamon and lxde but I can't quite get it with kde. I can lock the screen if I run the shell script from a terminal as root but when I remove the yubikey the shell script returns error code 1.

Here's my shell scripts:

ykgone.sh

#! /bin/sh if [ -z "$(lsusb | grep Yubikey)" ] ; then if [ ! -z "$(ps aux | grep cinnamon-session | grep -v grep)" ] ; then /bin/su rjonasz -c "DISPLAY=:0 cinnamon-screensaver-command -l" elif [ ! -z "$(ps aux | grep startkde | grep -v grep)" ] ; then /usr/bin/sudo -u rjonasz -H -i /usr/local/bin/lockkde.sh else /bin/su rjonasz -c "DISPLAY=:0 xscreensaver-command --lock" fi fi

lockkde.sh

#! /bin/sh

kde_pid=`pidof kdeinit5` export `cat /proc/$kde_pid/environ|grep -ao 'DBUS_SESSION_BUS_ADDRESS=[[:graph:]]*'` /usr/bin/qdbus org.freedesktop.ScreenSaver /ScreenSaver Lock

I can't seem to figure this one out.

Thanks for any help!

Are you sure the PATH is set the same when run from a terminal versus when run by your key being removed? Try for debugging to do at the start of the script: echo $PATH > /tmp/$$.path.env Then after running it both ways you should have a file for each PID that did it that you can compare. -- Len Sorensen
