they have their uses as a teaching tool, but the only way to really learn and understand Linux, is to install it and use it
Thank you @Brickwizard and @osprey for the fast replies.The answer is pretty much a no. Below is a pic of a painful few minutes waiting for the "terminal" to actually respond, and it ended up with a "system error" that stopped the trial altogether. Far better to access the linux terminal from a live disk which will provide a much more responsive experience. Better still is an actual installation of a linux distribution on a computer.
For software development though, where one is storing one's code in whatever forms, it would really benefit from a full linux installation on a computer so that access and storage are readily accessible.
