Anything you can do from a command line you can just type it as a line in a .BAT file (create it with notepad) and it will execute. I used to have a video program which would crash the computer unless I changed some settings before starting it. Of course, I always forgot this, so I wrote a BAT file automating this.
I understand your situation but I am not sure what to recommend. First, while you might be able to achieve something like what you are saying, it may be more trouble than it’s worth. Things change continually and you will find yourself making changes to whatever you did to automate the tasks.
I have had a couple of old aunts of mine ask me similar things: They want to use a computer without the trouble of having to learn how to use a computer. I have told them both it is not worth the trouble and they can live without email. Let’s face it, people who put a lot of effort into learning about computers, still have trouble. I do not think it is realistic to expect someone to be able to use a computer without some learning. Too many things can go wrong at any time. Trying to automate too much for people like that generally doesn’t work because so many things can go wrong. The slightest change throws the whole thing out the window. It might be easier if you do all the downloading, processing etc, and then email it to him and he just prints it out.
Otherwise I would be more inclined to sit down with him and go over the procedure step by step and have him write it down as a list. That way, after a few times he would begin to actually understand what he is doing. I have used this approach with another aunt. Heer initial attitude was “I am too dumb for this, I can’t do it, it’s too difficult”. She gave up without trying. By making her do it step by step and take notes, after a few times she realized, it was not so difficult and she was not so dumb.
Some people just have a negative attitude. I had a cousin who just refused to learn and use some basic vocabulary and would call me saying things like “I hit the thingie and nothing happened” . What can I make of that? Even though I told her a hundred times, she refused to say “icon” and preferred “thingie”. I guess “icon” sounded too nerdy.
My attitude is that people can learn if the want to and, if they don’t want to, then they should not expect to be able to use the computer.
But going back to automating tasks, I have also found out my computer is much more stable and less prone to crashing if I start tasks one by one manually. If they all start together from a BAT file or from the startup folder, they seem to interfere with each other.
Anyway, some things you might want to think about as they may be helpful:
.BAT files
Java script (also an executable text file but can do much more than a simple BAT file)
Task scheduler
Macros in the Applications programs
VPN (Virtual Private Network) allows you to access the other computer over the Net like it is on your local network.
