Thanks for the tip Mauro, Lennart! It turns out the problem was with not
having the DISPLAY variable set properly. So in lockkde.sh I invoke
qdbus this way
Konsole output
DISPLAY=:0 /usr/bin/qdbus org.freedesktop.ScreenSaver /ScreenSaver Lock
And now it works!
Thanks again,
Randy

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!
