📸 screenshot: Better macOS screenshots via the Terminal
screenshot is a command line utility that lets you specify an application name and window title in order to take a screenshot of a specific window.
screenshot, you can capture windows belonging to an application, or only an application's windows with certain titles.
Justification and Use Case
screencapture utility is not developer friendly.
To programmatically take a screenshot of an application, or a specific window, you must supply a window ID to
In order to find a window's window ID, you'll need call out to Quartz.
In newer versions of macOS, the
screencapture utility improves the user experience slightly: you can run the command and then click on the window you'd like to capture.
However, that necessitates that the user clicks a window each time. You cannot include this as part of an automated pipeline.
To that end, I use this utility to automatically generate screenshots of web, mobile and desktop applications.
Take a screenshot of the current Terminal window and view it with Preview.app:
open "`screenshot Terminal`"
Take a screenshot of the Pycharm application with the window title containing "screenshot":
screenshot Pycharm -t screenshot
