How to Stop Commands from Appearing in Bash History

I usually don't want my secrets to show up in my bash history in the $HOME/.bash_history file. Long ago, folks told me that using a trailing space will solve this issue, but it didn't. Apparently, there's some extra stuff to do

Just do

HISTCONTROL=ignoreboth

The above also helps with getting rid of duplicate commands from the bash history, which is pretty cool 🆒😎👌 since I use fzf https://github.com/junegunn/fzf to search through my history and choose commands, and when I search through a command with some strings, sometimes same result shows up multiple times - so many times that it's crazy and I just wish it just showed one unique result and get rid of duplicates, now this is possible because fzf looks at my $HOME/.bash_history only to look at all my past commands and if the bash history file contains unique commands, all is good, right? ;) By the way, I use fzf as part of my Ctrl + r keybinding for reverse search over all commands.

fzf has so many ideas for keybindings themselves - https://github.com/junegunn/fzf?tab=readme-ov-file#key-bindings-for-command-line , apart from community's ideas 💡😄
