To analyze my own computer usage, not to spy on anyone (although it crossed my mind), I want to have cron capture the current screen every minute.
* * * * * /bin/bash -c "/usr/sbin/screencapture /somedir/screen.png"
in the crontab will execute and take a screen capture. However, it is totally black because it is not running as, well, me. Any idea how to allow a cron job to capture my screen?
Update: I added a
say whoami to the same cron command and it confirms it is running as my user (no sudo or other users involved). I access the crontab from a terminal as myself.
So, it runs as me, but is not attached to my windowing system. Any ideas?
