The ‘history’ command available in Bash can be used to simply display your shell history, however there’s also a whole lot more that you can do with it, which we’ll demonstrate here.
Bash history allows us to quickly see what has been executed previously on a system, allowing you to hold users at least somewhat accountable for their actions (more on this later). It’s also useful if you’ve run something before and forgot the command, I can’t begin to tell you the number of times that I’ve done this!
