It takes a lot of delusions/lack of experience to imagine Linux is completely fragmented and uses completely different programs, daemons and configuration

1. Linux has used the same base commands (grep, cat, tail, etc) for decades. Longer than powershell (and longer than MacOS)
2. What "tutorial"? Bash learning one? What exactly are you "learning" in CLI? Unix scripting was part of my University course, and NOTHING has changed since doing it 20 years ago
3. All the major distros are using SystemD now, the freedesktop base,Pulseaudio (or pipewire) and the only distinction is generally package managers. But, even a lot of software is available on flatpak.
4. The real difference is configuration tools. The majority are the same. And, if you're doing learning server administration and struggle to differentiate a tutorial between SUSE Server and Ubuntu server, then you SHOULDN'T be administrating servers
5. Most Daemons are the same too (everyone uses Samba, etc)
6. There are literally GUI tools for mostly everything.
7. Any common distribution has EXCELLENT documentation regarding almost anything.
8. The claim that 1% of that help is malicious is laughable.

As per always, this post is lacking actual examples, of where people use CLI these days. Probably thats because in practice, there are very few that affect newbies that actually exist.
