Full Discussion: Capture std out snapshot after 15 seconds

Capture std out snapshot after 15 seconds
I have a program that scans and updates its results to std out every second. I would like to capture its output for further processing, but there is a catch. I would like to capture a snapshot after about 15 seconds as the results become more accurate and close the program.
Obviously I can simply use > temp_file which I can use by grabbing the last n lines, and close the program after 15 seconds but surely there is a better way?

Just looking for a general idea to get me in the right direction.

TLDR: Is there a way to capture the std out of a program directly before it closes?

NAME

       gnome-screenshot, gnome-panel-screenshot - GNOME screenshot utility

       gnome-screenshot  | gnome-panel-screenshot [--border-effect=effect] [--delay=int] [--include-border] [--interactive] [--window] [gnome-std-

DESCRIPTION

       gnome-screenshot allows users to capture the screen image of a window or the complete  screen.	gnome-panel-screenshot	is  a  symlink	to

       If  the	--window  option is used, you must move the mouse pointer to the window to be captured. The --delay option is always used with the
       --window option, to allow sufficient delay to set up the required screenshot. Once you have captured the window region, you  are  presented
       with a dialog showing a preview of the snapshot and the choice to save the image.

OPTIONS

       The following options are supported:

       --border-effect=effect  Effect to add to the border.

       --delay=int	       Pause for int seconds before capturing the window or screen

       --include-border        Include the window border with the screenshot.

       --interactive	       Interactively set options.

       --window 	       Capture a screenshot of the window in which the mouse pointer is located.
