The screencapture
utility has a -w
switch which allows capturing the front window, but only after highlighting the window and getting a click from the user.
Is there any way to capture the front window non-interactively using some shell command?

The
-l
option allows capturing a window by ID. It is only shown in the help message and not on the man page.I don't know any way to find the window IDs that would work with all applications though. This doesn't work with Preview, Activity Monitor, or Chrome:
screencapture -l $(osascript -e 'tell application (path to frontmost application as text) to id of window 1') /tmp/screencapture.png
