I get the following interactive prompt (navigatable using Up Down)when I press Ctrl+R using bash. What is this plugin/configuration? I'd like to install this on my other servers. Tried to search on google to no avail.
That behavior is part of the command
fzf. You can follow this guide: fzf - command line fuzzy finder to install it on your operating system.
In my case (once installed) I had to source these files:
source /usr/share/bash-completion/completions/fzf source /usr/share/bash-completion/completions/fzf-key-bindings
In other cases might source the files from a different path:
source /usr/share/doc/fzf/examples/completion.bash source /usr/share/doc/fzf/examples/key-bindings.bash
If you want to avoid typing each time those commands you can add those lines to your
echo -e 'source /usr/share/bash-completion/completions/fzf\nsource /usr/share/bash-completion/completions/fzf-key-bindings' >> ~/.bashrc echo -e 'source /usr/share/bash-completion/completions/fzf\nsource /usr/share/bash-completion/completions/fzf-key-bindings' >> ~/.bash_profile
