fzf: fuzzy finder for your shell
================================
fzf is a general-purpose fuzzy finder for your shell.
It was heavily inspired by [ctrlp.vim](https://github.com/kien/ctrlp.vim).
Requirements
------------
fzf requires Ruby.
Installation
------------
Download fzf executable and put it somewhere in your search $PATH.
```sh
mkdir -p ~/bin
wget https://raw.github.com/junegunn/fzf/master/fzf -O ~/bin/fzf
chmod +x ~/bin/fzf
```
Or you can just clone this repository and run
[install](https://github.com/junegunn/fzf/blob/master/install) script.
```sh
git clone https://github.com/junegunn/fzf.git
fzf/install
```
Make sure that ~/bin is included in $PATH.
```sh
export PATH=$PATH:~/bin
```
Install as Vim plugin
---------------------
You can use any plugin manager. If you don't use one, I recommend you try
[vim-plug](https://github.com/junegunn/vim-plug).
1. [Install vim-plug](https://github.com/junegunn/vim-plug#usage)
2. Edit your .vimrc
call plug#begin()
Plug 'junegunn/fzf'
" ...
call plug#end()
3. Run `:PlugInstall`
Then, you have `:FZF [optional command]` command.
```vim
:FZF
:FZF find ~/github -type d
```
Usage
-----
fzf will launch curses-based finder, read the list from STDIN, and write the
selected item to STDOUT.
```sh
find * -type f | fzf > selected
```
Without STDIN pipe, fzf will use find command to fetch the list of
files (excluding hidden ones).
```sh
vim `fzf`
```
### Key binding
Use CTRL-J and CTRL-K (or CTRL-N and CTRL-P) to change the selection, press
enter key to select the item. CTRL-C will terminate the finder.
The following readline key bindings should also work as expected.
- CTRL-A / CTRL-E
- CTRL-B / CTRL-F
- CTRL-W / CTRL-U
Useful bash binding and settings
--------------------------------
```sh
# vimf - Open selected file in Vim
alias vimf='vim `fzf`'
# fd - cd to selected directory
fd() {
DIR=`find ${1:-*} -path '*/\.*' -prune -o -type d -print 2> /dev/null | fzf` && cd "$DIR"
}
# fda - including hidden directories
fda() {
DIR=`find ${1:-*} -type d 2> /dev/null | fzf` && cd "$DIR"
}
# CTRL-T - Open fuzzy finder and paste the selected item to the command line
bind '"\er": redraw-current-line'
bind '"\C-t": " \C-u \C-a\C-k$(fzf)\e\C-e\C-y\C-a\C-y\ey\C-h\C-e\er"'
```
