fzf is a general-purpose command-line fuzzy finder.

It's an interactive Unix filter for command-line that can be used with any
list; files, command history, processes, hostnames, bookmarks, git commits,
etc.

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

fzf project consists of the following components:

- `fzf` executable
- `fzf-tmux` script for launching fzf in a tmux pane
- Shell extensions
    - Key bindings (`CTRL-T`, `CTRL-R`, and `ALT-C`) (bash, zsh, fish)
    - Fuzzy auto-completion (bash, zsh)
- Vim/Neovim plugin

You can [download fzf executable][bin] alone if you don't need the extra
stuff.

to install fzf.

```sh
brew install fzf

# To install useful key bindings and fuzzy completion:
$(brew --prefix)/opt/fzf/install
```

fzf is also available [via MacPorts][portfile]: `sudo port install fzf`

[portfile]: https://github.com/macports/macports-ports/blob/master/sysutils/fzf/Portfile

### Using git

Alternatively, you can "git clone" this repository to any directory and run
[install](https://github.com/junegunn/fzf/blob/master/install) script.

```sh
git clone --depth 1 https://github.com/junegunn/fzf.git ~/.fzf
~/.fzf/install
```

[![Packaging status](https://repology.org/badge/vertical-allrepos/fzf.svg)](https://repology.org/project/fzf/versions)

### Windows

Pre-built binaries for Windows can be downloaded [here][bin]. fzf is also
available via [Chocolatey][choco], [Scoop][scoop], and [Winget][winget]:

| Package manager | Command              |
| --------------- | -------------------- |
| Chocolatey      | `choco install fzf`  |
| Scoop           | `scoop install fzf`  |
| Winget          | `winget install fzf` |

[choco]: https://chocolatey.org/packages/fzf
[scoop]: https://github.com/ScoopInstaller/Main/blob/master/bucket/fzf.json
[winget]: https://github.com/microsoft/winget-pkgs/tree/master/manifests/j/junegunn/fzf

Known issues and limitations on Windows can be found on [the wiki
page][windows-wiki].

[windows-wiki]: https://github.com/junegunn/fzf/wiki/Windows

### As Vim plugin

If you use
[vim-plug](https://github.com/junegunn/vim-plug), add this line to your Vim
configuration file:

```vim
Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
```

`fzf#install()` makes sure that you have the latest binary, but it's optional,
so you can omit it if you use a plugin manager that doesn't support hooks.

For more installation options, see [README-VIM.md](README-VIM.md).

Upgrading fzf
-------------

fzf is being actively developed, and you might want to upgrade it once in a
while. Please follow the instruction below depending on the installation
method used.

- git: `cd ~/.fzf && git pull && ./install`
- brew: `brew update; brew upgrade fzf`
- macports: `sudo port upgrade fzf`
- chocolatey: `choco upgrade fzf`
- vim-plug: `:PlugUpdate fzf`

Building fzf
------------

See [BUILD.md](BUILD.md).

Usage
-----

fzf will launch interactive 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)
```

> *:bulb: A more robust solution would be to use `xargs` but we've presented
> the above as it's easier to grasp*
> ```sh
> fzf --print0 | xargs -0 -o vim
> ```

>
> *:bulb: fzf also has the ability to turn itself into a different process.*
>
> ```sh
> fzf --bind 'enter:become(vim {})'
> ```
>
> *See [Turning into a different process](#turning-into-a-different-process)
> for more information.*

### Using the finder

- `CTRL-K` / `CTRL-J` (or `CTRL-P` / `CTRL-N`) to move cursor up and down
- `Enter` key to select the item, `CTRL-C` / `CTRL-G` / `ESC` to exit
- On multi-select mode (`-m`), `TAB` and `Shift-TAB` to mark multiple items
- Emacs style key bindings
- Mouse: scroll, click, double-click; shift-click and shift-scroll on
  multi-select mode

### Layout

fzf by default starts in fullscreen mode, but you can make it start below the
cursor with `--height` option.

```sh
vim $(fzf --height 40%)
```

Also, check out `--reverse` and `--layout` options if you prefer
"top-down" layout instead of the default "bottom-up" layout.

```sh
vim $(fzf --height 40% --reverse)
```

You can add these options to `$FZF_DEFAULT_OPTS` so that they're applied by
default. For example,

```sh
export FZF_DEFAULT_OPTS='--height 40% --layout=reverse --border'
```

### Search syntax

Unless otherwise specified, fzf starts in "extended-search mode" where you can
type in multiple search terms delimited by spaces. e.g. `^music .mp3$ sbtrkt
!fire`

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

If you don't prefer fuzzy matching and do not wish to "quote" every word,
start fzf with `-e` or `--exact` option. Note that when
