I don’t have any books in particular to recommend, but with homelab’ing we should be learning about the command line of our OS(Powershell, terminal(bash, zsh)).

Learning the ins and outs of something like bash, cron, environment variables, for loops, systemd services(managing, creating your own), command line networking…all things I’ve had to learn to either setup, manage, and/or troubleshoot my homelab.

So maybe basic Linux command line books? Probably O’Reilly has some along with bash.
