Today I finished this Linux terminal commands tutorial. I started it yesterday, but only got halfway through it then, and I only finished it today because at this point some of the sections at the end are irrelevant for me, so I just read through them.
Stopped at the move/rename 'mv' command yesterday, and started with the copy 'cp' command today, so this was straightforward to use. For both of these it is recommended to use the -i option so it warns you of existing files, so you don't accidentally permanently overwrite something important.
And for directories if you want to copy/move in full, with all files within, you need to use the -R recursive option, otherwise it will only copy/move the directory as a file and not as a directory. Here's an explanation I found.
I found it confusing that sometimes -r means different thing, but in these commands at least -R is always referencing resistivity. -r however can be many many different things in different commands, and I do not know if only this tutorial loves to use these options or if these options are always particularly important (because if so then it seems to be always a good idea to check the manual before assuming what the -r option is doing for a particular command).
remove direcotry (rmdir) and remove (rm) explanations were clear.
As I worked through the tutorial, more and more explanations were neglected that I felt like they should be included. I still think the tutorial is good, you just have to be prepared to look up more things because the pace picked up and (IMO) essential parts were not explained.
One such example is the choice for explaining the use of 'locate' instead of 'find', especially so because, as I learned, 'locate' is not included as default in many Linux distributions (like mine). It would have been nice if this is mentioned in the tutorial, with at least a link to steps to install -- or if 'find' were explained, regardless if it's more complex or not.
The quick tip about the documentation symbols for regular user executing commands vs root user commands ($ and # respectively) was something really important, that I could have used previously but never seen explained before anywhere.
The bit about installing was also useful, and the side note about 'piping a command' was also something that could have used a paragraph worth of explanation of what it is, and not just be assumed you know what it means on an basics tutorial... Here's an article for it.
After this point, the only other section of interest for me right now was the one about file compression, but here too were many things that I needed to look up because of lack of explanation, that I think would have made the tutorial better if included.
For example here's a site about the tar (tape archive) command that explains the options that were used in the tutorial but not explained why they are used... huge oversight IMO.
Overall I recommend the tutorial, it started off really good, and it was good all the way, just needed more looking up towards the end. I guess the article was getting too long and maybe the author did not want to make it even longer, who knows. Now I just need to come up with some ideas to use this knowledge in the near future, so it doesn't just disappear out from my brain with time.
