Just to clarify, does ~/ mean home directory? I got confused when the reading started talking about passwords. maybe more on the tilde Also, I'm a bit confused about how drop works. Every time you want to drop stuff, are you creating a new file just for that?  Going over the commands again would be really helpful, as I have not quite memorized them yet, especially the drop and copy commands ssh and scp I don't really get what the shell and ssh are, and how the server works. / I am still a bit confused scp and ssh. / I'm a little bit confused with the part regarding ssh and scp. I was wondering if we could talk more about tar files: How are they opened? How are they used? Also, what are the pros and cons of using tar/gzip vs. zip/unzip? / I would like to learn more about the tarfiles. / I'd like to go over the tarfile concepts in more depth to further understand how they work and how to utilize them. I would like to talk more about when to use relative and absolute paths when linking something onto a webpage. How wildcards work i'm not sure how to save any work i've done or how to properly close/log out of unix still slightly unsure of the difference/functions of code and cat I am still unfamiliar with the idea of remote and whose database we are working on. Do different databases mean different trees? Or different subtrees within the same tree? Pretty confusing to visualize for me! I would like to get more practice with working in the terminal overall, however I think I especially would like to talk about the different deletion methods and possible safeguards/things to look out for when using them. I also would like to talk more about/practice how to drop files. What rm* does and what 'mv' means? Also, can I understand tar and gzip as doing the opposite functions? Tar & gzip; difference between the function of "drop" and commands about removing files & directories (other than "drop" only works on the CS server). Thank you! I do not think I fully understand "tar" or "scp" commands yet/ none. I think it would be nice to have a clearer list, perhaps, of all of the commands that we have learned thus far + an example of their notation, just so we can see exactly how they are used right next to it.
