I always thought I could drag-drop a
target file onto a
src executable in Finder, and make macOS perform
But I don't seem to be able to do it and I’m not even able to recall if this was something that used to work or there’s a change where a program needs to have some attributes to allow this.
At the command line, the
dec program would take core.enc as standard in or an argument.
Is this something Finder can do with any programs or just ones that have some documented metadata / associated files?
