fzf - Fuzzy finder for your shell
=================================

fzf is a general-purpose fuzzy finder for your shell.

![](https://raw.github.com/junegunn/i/master/fzf.gif)

It was heavily inspired by [ctrlp.vim](https://github.com/kien/ctrlp.vim) and
the likes.

Requirements
------------

fzf requires Ruby (>= 1.8.5).

Installation
------------

Download [fzf executable](https://raw.github.com/junegunn/fzf/master/fzf) 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 Ruby gem

fzf can be installed as a Ruby gem

```
gem install fzf
```

It's a bit easier to install and update the script but the Ruby gem version
takes slightly longer to start.

### Install as Vim plugin

You can use any Vim plugin manager to install fzf for Vim. 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`

Usage
-----

```
usage: fzf [options]

  -m, --multi      Enable multi-select
  -x, --extended   Extended-search mode
  -s, --sort=MAX   Maximum number of matched items to sort. Default: 500
  +s, --no-sort    Do not sort the result. Keep the sequence unchanged.
  +i               Case-sensitive match
  +c, --no-color   Disable colors
```

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. (You can override the default command with
`FZF_DEFAULT_COMMAND`)

```sh
vim $(fzf)
```

If you want to preserve the exact sequence of the input, provide `--no-sort` (or
`+s`) option.

```sh
history | fzf +s
```

### 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

If you enable multi-select mode with `-m` option, you can select multiple items
with TAB or Shift-TAB key.

### Extended-search mode

With `-x` or `--extended` option, fzf will start in "extended-search mode".

In this mode, you can specify multiple patterns delimited by spaces,
such as: `^music .mp3$ sbtrkt !rmx`

| Token    | Description                      | Match type           |
| -------- | -------------------------------- | -------------------- |
| `^music` | Items that start with `music`    | prefix-exact-match   |
| `.mp3$`  | Items that end with `.mp3`       | suffix-exact-match   |
| `sbtrkt` | Items that match `sbtrkt`        | fuzzy-match          |
| `!rmx`   | Items that do not match `rmx`    | inverse-fuzzy-match  |
| `'wild`  | Items that include `wild`        | exact-match (quoted) |
| `!'fire` | Items that do not include `fire` | inverse-exact-match  |

Usage as Vim plugin
-------------------

If you install fzf as a Vim plugin, `:FZF` command will be added.

```vim
:FZF
:FZF --no-sort
```

You can override the command which produces input to fzf.

```vim
let g:fzf_command = 'find . -type f'
```

Most of the time, you will prefer native Vim plugins with better integration
with Vim. The only reason one might consider using fzf in Vim is its speed. For
a very large list of files, fzf is significantly faster and it does not block.

Useful bash examples
--------------------

```sh
# vimf - Open selected file in Vim
vimf() {
  FILE=$(fzf) && vim "$FILE"
}

# 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"
}

# fh - repeat history
fh() {
  eval $(history | fzf +s | sed 's/ *[0-9]* *//')
}

# fkill - kill process
fkill() {
  ps -ef | sed 1d | fzf -m | awk '{print $2}' | xargs kill -${1:-9}
}

# (Assuming you don't use the default CTRL-T and CTRL-R)

# CTRL-T - Paste the selected file path into 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"'

# CTRL-R - Paste the selected command from history into the command line
bind '"\C-r": " \C-e\C-u$(history | fzf +s | sed \"s/ *[0-9]* *//\")\e\C-e\er"'
```

zsh widgets
-----------

```sh
# CTRL-T - Paste the selected file(s) path into the command line
fzf-file-widget() {
  local FILES
  local IFS="
"
  FILES=($(
    find * -path '*/\.*' -prune \
    -o -type f -print \
    -o -type l -print 2> /dev/null | fzf -m))
  unset IFS
  FILES=$FILES:q
  LBUFFER="${LBUFFER%% #} $FILES"
  zle redisplay
}
zle     -N   fzf-file-widget
bindkey '^T' fzf-file-widget

# ALT-C - cd into the selected directory
fzf-cd-widget() {
  cd "${$(find * -path '*/\.*' -prune \
          -o -type d -print 2> /dev/null | fzf):-.}"
  zle reset-prompt
}
zle     -N    fzf-cd-widget
bindkey '\ec' fzf-cd-widget

# CTRL-R - Paste the selected command from history into the command line
fzf-history-widget() {
  LBUFFER=$(history | fzf +s | sed "s/ *[0-9]* *//")
  zle redisplay
}
zle     -N   fzf-history-widget
bindkey '^R' fzf-history-widget
```

Tips
----

### Faster startup with `--disable-gems` options

If you're running Ruby 1.9 or above, you can improve the startup time with
`--disable-gems` option to Ruby.

- `time ruby ~/bin/fzf -h`
    - 0.077 sec
- `time ruby --disable-gems ~/bin/fzf -h`
    - 0.025 sec

Define fzf alias with the option as follows:

```sh
alias fzf='ruby --disable-gems ~/bin/fzf'
```

### Incorrect display on Ruby 1.8

It is reported that the output of fzf can become unreadable on some terminals
when it's running on Ruby 1.8. If you experience the problem, upgrade your Ruby
to 1.9 or above. Ruby 1.9 or above is also required for displaying Unicode
characters.
