One a related note there is one program that I absolutely miss on Linux called everything (on windows). The closest I can find is mlocate but it does not have a GUI but more importantly it does not index my Windows or NTFS drives. Would appreciate any suggestions if someone knows something like 'everything' for Ubuntu.
From the linux command-line, I like fzf ( https://github.com/junegunn/fzf ), that you can instruct to use the faster fd ( https://github.com/junegunn/fzf#environment-variables ). Fzf even offers keybindings for your shell. For example, it binds Alt+C to fuzzy-finding a directory, and Enter cds to it ( https://github.com/junegunn/fzf#key-bindings-for-command-lin... ).
Fzf is great for other things too; here is a fish function to bing Alt+G to fuzzy-pick a Git branch and jump to it:
function fish_user_key_bindings
bind \eg 'test -d .git; or git rev-parse --git-dir > /dev/null 2>&1; and git checkout (string trim -- (git branch | fzf)); and commandline -f repaint'
bind \eG 'test -d .git; or git rev-parse --git-dir > /dev/null 2>&1; and git checkout (string trim -- (git branch --all | fzf)); and commandline -f repaint'
end
