I want to use the quick action: Remove Background, which is available in the Finder of MacOS Ventura (right click -> quick actions -> Remove Background)

Does someone know how to do it with a Terminal command-line / shell script?

I tried to record the action in Automator, but without any luck. It ends up with a Watch Me Do action which I can't do anything with. But maybe i'm doing something wrong and there is another way. With the action I don't want the Finder to come up front. So on a way that the app with the shell function keeps upfront. I'm using Max from cycling'74 for the shell commands.

Thanks in advance!

    There is a shortcuts command and an automator command that you can use to trigger Shortcuts and Automator workflows.

  • Thanks a lot! I never used Shortcuts, but i made a shortcut which removes the background and with shortcut command-line it's perfect.

  • @Aart could you share your Shortcut? can you batch remove backgrounds? shortcuts run "Remove Background" -i /path/to/folder/*.jpg [?]

  • You can start by using screencapture -iW ~/Desktop/screenshot.png. This will capture a screenshot without the background. You can then use open -a "Preview" ~/Desktop/screenshot.png to open the image in Preview.

  • Of course, you could make this a shell script, make it executable with chmod +x remove_background.sh and run it with ./remove_background.sh. (remove_background is just a sample name for the script)

I use GraphicsMagick (FOSS) to run a one-liner to remove the background from images. Below is the command I use to make the background transparent.

gm convert infile.png -fuzz 5% -transparent "#ffffff" outfile.png

What this is doing is taking the infile.png file and with the convert command, making transparent the color defined in hex; in this case white (#ffffff)

You may have to adjust the “fuzz” factor depending on how precise you need it. -fuzz gives you some wiggle room by allowing close to the color you specified to be selected.
