A good friend who has used Macs professionally for years has asked me to send him a big stack of HTML documents, and my instinct is to put them into a tarball, b2zip it, and send him that. I asked whether he could handle it, and he told me to send each document separately, uncompressed. Ugh. I use Linux, so I know you folks have an excellent OS that is BSD-based and can handle lots of bash commands I use. Accordingly I want to tell my friend how to do it all in one easy step from the CLI. He has no idea what I'm talking about, does not know how to get to the CLI, and did not even know Macs have them until I mentioned it to him. So could you kindly provide my friend with a no-assumptions, comprehensive, clear list of beginner's instructions that will tell him exactly what to do to? He needs to: 1. Get into the CLI 2. Locate the tarball he downloaded from Gmail 3. Unzip it and open it 4. Get out of the CLI and back into the GUI. I would deal with the tarball this way: $ tar xjvf ./texts.tar.bz2 Could he use that command? I don't have any idea how to leave the graphic world on a Mac. My view is that fulfilling his request will be a real pain for me and a lot of work for him as well if I don't use a tarball, and he needs to learn something about the OS he's using. I'll be interested to see how Mac users do it, as well. Yes, I expect the job can be done in the GUI on a Mac, but as I say, I would like to expand his universe (and mine) just a bit. Dragging him out of the GUI won't hurt him, and the learning experience could give him a bit more respect for the power and flexibility of the OS he uses daily. TIA!
