I love it XD

I’d say that journalctl is not only boot, but every service that runs on the computer has its logs collected through it, so you can use it as journalctl --grep="your regex". You can also add -k to check kernel logs, -b -n to check nth precedent boot or -b n to check the absolute nth boot. There is a lot that you can check with it and it is quite nice :)

Otherwise, I like eza as an ls replacement, or batcat as a human friendly cat

with zsh, you can use it, and then press space to have the !! replaced by the previous command to be able to edit it :)
