fzf is a pretty neat command history search tool. It’s not found in the Xubuntu 18.04 repositories. Here’s how to install it:
First, open a terminal and paste or type this:
git clone --depth 1 https://github.com/junegunn/fzf.git ~/.fzf
Now the git repository has been cloned onto your system. Next, run the installer:
~/.fzf/install
With the install complete, restart your terminal or use the following command:
source ~/.bashrc
All done! Now to use fzf, press Ctrl+R while using the terminal. This will let you search past commands and you can use the arrow keys to navigate and select past commands.
