We often use quite complex commands in our terminals. We usually either search for them over and over again, save them somewhere to refer to later, or try to remember them. However, there is another option — to use autocompletion in terminal based on the history of used commands.

Unix system terminal stores the history of recent commands.
For Windows users the new version of Powershell also supports this too.
So we can quickly search in that history list using

By default terminal, history will store the last 500 commands, but you can manually set size by setting in your

I definitely would suggest using at least one of the above options on your everyday work in the terminal, because it worths it. Also, you can combine some of them, like using
