Personally I prefer the kebab/dot conventions simply because they allow for easy "navigation" with (ctrl+arrow keys) between each part. What are your preferences when it comes to this? Did I miss any schemes?
25% Camel case, 25% Pascal and 50% of the time flatcase. It drives me insane when I try and autocomplete a folder only to realise it was Downloads instead of downloads. I keep telling myself i will go through and make it all flatcase but I put it off because i tell myself i will rebuild my computer next week every week.
Zsh is a shell like bash that supports shell scripting like bash (though with some syntactical differences). It's a bit more like ksh than bash, but anyone familiar with bash will have no problems with zsh.
You can check out oh-my-zsh for an accessible preconfigured version of it (though I'd suggest installing via your package manager rather than the script on their website). I like the jreese theme.
Never thought about making the home folders flatcase, thanks, takes all of 2 minutes btw.
If anybody else wants to do it, remember to edit ~/.config/user-dirs.dirs with your new flatcase folders.
