This might be a very subjective question, but I'm curious. I'm looking for a book that begins at the beginning and progresses through the intricacies of PowerShell 6. I have the latest edition of Step by Step, version 5.0, but is there a later one? Or is 5.0 material good to begin with and then slowly move up to version 6 through other means? I'm particularly interested in becoming proficient so that I can sell the PowerShell pitch to my Linux-intoxicated friends and associates.
