So compared to plain bash without autocomplete and Ctrl+R it may be useful. It is probably a step back for everyone else.

I think it could be much worse than even a plain shell with ^R, as the llm will be slower than the normal history search and probably has less context than the $HISTFILE.

Yes, stablediffusion

afaik yes, at least the arch kernel has selinux enabled, but you need to install the user space tools from the AUR.

I think a tag system as suggested by others makes the most sense, as NSFW and NSFL aren’t mutually exclusive.

You don’t even need to look at the extension to identify most file formats, as there are unique magic numbers stored at the beginning of most (binary) formats. Only when a single binary format is reused to appear as two different formats to the user, e.g. zip and cbz are extensions relevant. This is how the file command and most (?) Linux file explorers identify files, and why file extensions are traditionally largely irrelevant on Linux/Unix.

This means your idea of suggesting software based on the file type is even more practicable than you described.

Keeping the details about vim in the extras is what I would do as well, but I would definitely tell the students that vim and vi exist, because they are the only editors available on many systems.

I would consider that ifconfig is deprecated on many distros and would therefore teach about iproute2 (mostly the ip and ss commands) instead. Additionally I would consider editing files essential, even if it is with nano.

Maybe mention more modern and simpler help tools like tldr, as they could be even more useful to beginners.

To introduce the shell and utilities, I would try to find a somewhat realistic use case that combines multiple aspects, like analyzing some files or spellchecking instead of simply mentioning every feature one by one.

Why not write your own version? Getting the temperatures is easy and portable with the sensors command from lm-sensors. The rest of the info is easy to get using various commands (e.g. uptime, free) combined with a bit of sed/grep/awk for formatting.

If you are looking for cheap storage, i recommend you check out diskprices.com . At least it helped me sometimes to find the disk with a low price per TB.

Of course anecdotes are of very limited usefulness, but I had exactly the opposite experience. The HDDs that failed on me, failed slowly with SMART errors that gave enough time to make a backup, and never failed completely. On the other hand I had a cheap SSD die completely and without any warning after only limited use, and experienced bit rot even on reputable vendors.

tl;dr choose what you want but make backups
