Bypass the trash

To carry D.L. Johnson's suggestion one further, select the file(s) you want to delete and use the two key combinations:

⌘+Delete

followed by

⌘+Shift+Delete.

That will move the files to the Trash bin and empty the bin in two key combinations.

Or you an use a keyboard macro app like Keyboard Maestro to do both of those keystroke combinations with just one keystroke, i.e. a function key for one key or Control+D, whatever floats your boat.

Automater created Drag & Drop app to delete files immediately. There is no "Undo"!

I got a Trashcan icon from

https://osxdaily.com/2010/07/29/add-a-trash-icon-to-the-desktop/

I did a Right-Click (Control-Click) on the trashcan icon on osxdaily.com, and selected "Save Image as..."

I opened the saved image in Preview, did a Select All, Copy.

Selected my Automator app, then Finder -> File -> Get Info

Click on the Automator icon in the upper left corner of the Get Info dialog box

Pasted the trashcan icon into the Get Info which put the trashcan icon on my Automator Drag & Drop delete app.

Drag & Drop any file on this Automator app, and it is deleted. Do Not Pass Go, Do Not Collect $200. The file is gone, and you cannot get it back.

Hello, gabosalbin.

The trash functions the way it does by design. It's kind of a safety net, if you will, allowing we mortal users to retrieve something we've thrown out. I can't tell you how often the feature has save me from making a mistake. If you've never had to retrieve something from the bin you should count yourself fortunate.

But to answer your question, there is a keystroke that will empty the trash: ⌘⇧⌫ (command-shift-delete).

It's quick and easy!

You could always create a Drag & Drop Automator app that deletes any file dropped on its icon. And then you could put a trashcan icon on the app. Place that somewhere you like on your desktop or on your Dock and you have instant delete.

I had to retrieve some of the files from the bin, but if I would to permanently delete something then I wouldn't retrieve it.

Which is why current personal computer operating systems use the trashcan/trashbin concept, and you periodicity empty the bin (sometimes you even review to make sure it is safe to really delete the files).

As I work from the command line 95% of the time at work (Unix software developer), I really REALY understand deleting my mistake with no "Give Backs".

I'm glad you found a way to live with the trashbin.

You already received a few brilliant suggestions for your consideration, but you can also configure your Mac to permanently empty Trash items after 30 days: Empty Trash Automatically.

I like the way you think.

I am so not used to considering all that Automator can do.

Glad to know you've resolved the issue. 🙂
