:) Reminds me of the transition from using DOS to using Windows Explorer for file management. Click/swipe/whoops... where did it go? When you're walking a neophyte through something on the phone, at the DOS prompt it was easy enough to instruct someone how to do something.
I personally think that every school kid should spend their first year on a computer at the DOS/CMD prompt. It leads to a much greater understanding of the file system.
For many years I had a lecture that I developed for folks that I called "The fully qualified filename". It took about an hour to go through, but at the end, you had a really good understanding of files, paths, and especially the "." and ".." directories.
Works great with SCP too. I love the shorthand that you can use with that.
That is a fully qualified name down to the system username used to access it.
KDE took this a little bit further, and actually borrowed a bit from ftp URLs using the "fish" protocol.
On a KDE system, an application that understands fish:// can retrieve a file securely by specifying something like this:
That tells it to use SSH to login to mysystem.foo.com as user zeugma, and get file1.txt from the /home/zeugma/Downloads directory. If you had your keys set up properly, you could do it without a password prompt. Nice.
