Hello,
I am trying to run a script to check gmail as described here (with
some errors)
https://wiki.archlinux.org/index.php/Xmobar#Gmail_integration

When I set the template to %mail% and restart xmobar, the bar refuses
to display. If I set the script to a non-existent file, I see xmobar
with a message "Could not execute command", so I know it's all
configured fine, but for the script that checks gmail. If I run that
script manually, I see a single integer value on standard output.

I can't seem to find any place that xmobar is logging to help identify
what is causing the error (xmobar refusing to display when asked to
Run Com my script.

Thanks for any pointers.
