etc.

[![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].

### 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 `--exact` is set,
`'`-prefix "unquotes" the term.
A single bar character term acts as an OR operator. For example, the following
query matches entries that start with `core` and end with either `go`, `rb`,
or `py`.
```
^core go$ | rb$ | py$
```
### Environment variables
- `FZF_DEFAULT_COMMAND`
- Default command to use when input is tty
- e.g.
