How about Fedora? Will it be usable, out of the box without learning new commands?Excellent free udemy : Master the commandline in 11.5 hours course.
This course stands out from the rest because it doesnt simply have you parrot commands, but it acutally teaches you how commands are out together.
It will teach you about commands, options, arguments, input / output redirection, piping, using the tee command with piping, making alias's , bash scripting concepts and an excellent overview of the file system
