happyfinder 
hf is a command line utility to quickly find files and execute a command - something like Helm/Anything/CtrlP for the terminal. It tries to find the best match, like other fuzzy finders (Sublime, ido, Helm).
Here is it in action:
If you have any suggestions, please open an issue.

This project wasn't implemented as an improvement to any of the projects below - I only knew about the text editor plugins (Anything, Helm, CtrlP, Sublime's native matching...). I wanted something similar to that for the command line, and a reason to use termbox-go, a great library for creating terminal-based apps.
- fzf is a blazing fast command-line fuzzy finder written in Go
- Selecta is a fuzzy text selector for files and anything else you need to select
- Pick is "just like Selecta, but faster"
- icepick is a reimplementation of Selecta in Rust
Those projects take the elegant route - the Unix way - in the sense they don't reimplement the "find files recursively" part. I didn't consider that route because I wanted hf to work in the Windows prompt as well.
Installation
If you have Go configured in your system, you should be able to install (and update) happyfinder with the command:
go get -u github.com/hugows/hf
Usage
The basic command is:
hf [path] [command]
The default path is the current folder.
The default command is the first valid of $GIT_EDITOR, $EDITOR, or vim
(subl on Windows).
To find in your git project, use:
hf -git [command]
(if -git is provided, then next argument (optional) is assumed to be a command)
If the binary name is 'hfg', the -git option is assumed.
This was done because Windows users have no easy way of creating command aliases.
A -cmd=<yourcmd> option is provided to simplify aliases. For example, I defined
iga (interactive git add) like this:
alias iga='hf -cmd="git add"'
Examples:
hf
hf -git
hf -git vim
hf ~/go/src/
hfg rm
hf . rm
Inside the app:
a-z0-9 Edit input string (those also work: backspace/C-a/C-e/C-k/Home/End)
Up/down Move cursor to next file
Space Toggle mark for current file and move to next
C-t Toggle mark for all files
C-s Toggle "run command in shell"
TAB Jump to edit command (and back)
RET Run command
ESC Quit
When editing the command, the string $FILES is special and will
replaced by the select (or marked) files, properly quoted.
