Taking timed screenshots in OS X #
Looking for a simple way to take screenshots at a set interval, I happened upon this solution which relies on cron. Unfortunately, cron cannot schedule jobs in increments of less than one minute, and I wanted to take screenshots every 3 seconds. Adding delay and repeat to the same script did the trick (note that the save directory has also been changed to the current user's Pictures folder):
repeat set DATE_TIME to do shell script "date +%Y_%m_%d_%H%M%S" set fname to DATE_TIME & ".png" do shell script "/usr/sbin/screencapture -x ~/Pictures/" & fname delay 3 end repeatUPDATE: Just found an open source REALbasic app called Timed Screenshot (2.5MB) that apparently does essentially the same thing. Haven't tried it yet since the AppleScript solution worked beautifully.
