Exactly. It may be a program that uses 5,000kb of files but only 2,000kb need to be downloaded.
That’s when you’ll see; “somefile already latest” over and over during the install process.
And that is another thing I enjoy to watch. As it is doing operations one file at a time during an install it actually explains with notes what each is and what is happening. You can learn a lot about Linux by reading these install operation notes it shares file by file.
Was it you who told me here one time to “never discount the power of the terminal utility”? If so thank you. You were absolutely right. There is still quite a bit of needed stuff out there that requires a command line install. And they only give Command line instructions for them. And it works slicker than snot. :)
