Digital Router Question:

At a very basic level, there really isn't one. As you progress up the chain however, you start to realize that there actually are a lot of differences in the power available to users (and admins) depending on how much you know about the different interfaces. Each of these utilities is a CLI- Command Line Interface- that allows for direct access to some of the most powerful utilities and settings in their respective operating systems. Command Prompt (cmd) is a Windows utility based very heavily on DOS commands, but has been updated over the years with different options such as long filename support. Bash (short for Bourne-Again Shell) on the other hand is the primary means of managing Unix/Linux operating systems and has a great deal more power than many of its GUI counterparts. Any Windows user that is used to cmd will recognize some of the commands due to the fact that DOS was heavily inspired by Unix and thus many commands have versions that exist in Bash. That being said, they may not be the best ones to use; for example while list contents (dir) exists in Bash, the recommended method would be to use list (ls) as it allows for much easier-to-understand formatting. Powershell, a newer Windows Utility, can be considered a hybrid of these two systems- allowing for the legacy tools of the command prompt with some of the much more powerful scripting functions of Bash.
