fzf

It’s a general purpose fuzzy finder written in Go that can be used with any list of things: files, processes, command history, git branches, etc.

For Zsh, it provides the following key bindings (overwrite existing ones), and they are very handy:

M-C: Directory search, cd into the selected directory
C-t: Paste the selected file path(s) into the command line. Useful to insert quickly paths into arguments of commands.
vi $(fd \.yaml|fzf): run a command with the selected item from fzf as argument
mv $(fd -t directory|fzf) ~/Temp/, DANGER: move a directory from selected path to ~/Temp/

Fuzzy completion mode

Select Files under parent directory: vi ../**<TAB>
Select Files under parent directory that match fzf: vi ../fzf**<TAB>
Select Files under your home directory: vi ~/**<TAB>

Select Host names: ssh **<TAB>
