For those serious about security on their Raspberry Pi 4 computers, regularly clearing the terminal history or bash history is advisable.
A chronological history of your entered terminal commands is automatically retained, which is great when you need to repeat or lookup a prior command. However, this can also become a security concern. What if someone gains access to your machine, opens a terminal window, and browses through your terminal history? If you are human, no doubt you will have (at some point) accidentally entered a password in a non-password field.
This article will show you how to quickly and easily clear the history of your terminal window.
