I’m sure this is obvious to people who study computer programming but to mere mortals it’s not!
Having done a few installs of e/os now, I have to say that the documentation is missing one vital piece of information for non-tech folk like me using the command line method:
Whenever it says “replace <…>” with the “name of your file” in the instructions, what it fails to mention is this will not work by replacing the name only.
In fact what you should do is drag the file you are wanting to flash (for example) to the Command Line or Terminal from its location on your hard drive and drop it onto the line you are writing… at the exact point of the “<…>” in the line. A small white preview box will appear as you hover over the point.
Then the command line will show the location in-line and all will be well!
The e/os install documentation does not mention this anwhere as far as I can see.
It’s not a guaranteed functionality you can assume as working this way for every user of different OS flavours and terminals/command lines out there.
But it’s good if it works this way.
terminal ergonomics: drag-n-drop gives you the absolute (“full”) path - but probably easiest is to work from the place where you downloaded (and extracted) the images into and use TAB-key completion after entering the first few letters of the filename.
In Linux, I either start by placing the file in the Home directory, then launching Terminal (which defaults to the Home directory when starting), then backspacing over the “<…>”, and then either type or paste the name of the file to that space on the command line.
Or, if I leave the file in Downloads (etc.), I launch Terminal and change from the default Home directory to the Downloads directory: cd Downloads. From there, I continue the operation.
