Using Linux Mint with Cinnamon.
I deleted some files using ShiftDel, so that they wouldn't go to the trash, but hoping they would be deleted immediately. However, the files are still there, they have only been renamed with a ~ at the end, making them invisible, but are not gone.
If I were to delete the tilde from the name the files would be restored. I see the functionality as some kind of safety net thug redundant with the trash can. If I was looking for a two step "safe" operation I would just send the files to the trash and then empty the trash.
Only by deleting the renamed files with ShiftDel again I can finally get rid of them.
So what is the One-Step operation to permanently delete files then?
