Boxcutter is a simple command line-driven screenshot program for Microsoft Windows. Below you find a short script I wrote that will take a screenshot of the full screen every 20 seconds until 100 screenshots are saved.
One usage scenario (I plan to use) is where you are running an OS installation within a Virtual Machine and want to take screenshots of the various stages of the installation without having to manually take a screenshot. You would just let the script run, it will probably produce more screenshots as needed, but these then can be deleted manually afterwards.
:: seconds to wait until taking next screenshot
:: maximum # of screenshots that will be taken
:: first prepare the filename using date and time string, cut off fractional seconds and replace
:: colons with dashes
:: Capture fullscreen
boxcutter.exe -f %FileName%.png
set /A count=start+1
if %count% gtr %maxcapture% GOTO :END
Echo Screen Capture batch process completed.
