Installation
------------
fzf project consists of the following components:
- `fzf` executable
- `fzf-tmux` script for launching fzf in a tmux pane
- Shell integration
- Key bindings (`CTRL-T`, `CTRL-R`, and `ALT-C`) (bash, zsh, fish)
- Fuzzy completion (bash, zsh)
- Vim/Neovim plugin
You can [download fzf executable][bin] alone if you don't need the extra
stuff.
[bin]: https://github.com/junegunn/fzf/releases
### Using Homebrew
You can use [Homebrew](https://brew.sh/) (on macOS or Linux)
to install fzf.
```sh
brew install fzf
# To build fzf from the latest source: brew install --HEAD fzf
```
> [!IMPORTANT]
> To set up shell integration (key bindings and fuzzy completion),
> see [the instructions below](#setting-up-shell-integration).
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
```
The install script will add lines to your shell configuration file to modify
`$PATH` and set up shell integration.

### Windows
Pre-built binaries for Windows can be downloaded [here][bin]. fzf is also
available via [Chocolatey][choco], [Scoop][scoop], [Winget][winget], and [MSYS2][msys2]:
| Package manager | Command |
| --------------- | ------------------------------------- |
| Chocolatey | `choco install fzf` |
| Scoop | `scoop install fzf` |
| Winget | `winget install fzf` |
| MSYS2 (pacman) | `pacman -S $MINGW_PACKAGE_PREFIX-fzf` |
[choco]: https://chocolatey.org/packages/fzf
[scoop]: https://github.com/ScoopInstaller/Main/blob/master/bucket/fzf.json
[winget]: https://github.com/microsoft/winget-pkgs/tree/master/manifests/j/junegunn/fzf
[msys2]: https://packages.msys2.org/base/mingw-w64-fzf
Known issues and limitations on Windows can be found on [the wiki
page][windows-wiki].
[windows-wiki]: https://github.com/junegunn/fzf/wiki/Windows
### Setting up shell integration
Add the following line to your shell configuration file.
* bash
```sh
# Set up fzf key bindings and fuzzy completion
eval "$(fzf --bash)"
```
* zsh
```sh
# Set up fzf key bindings and fuzzy completion
eval "$(fzf --zsh)"
```
* fish
```fish
# Set up fzf key bindings
fzf --fish | source
```
> [!NOTE]
> `--bash`, `--zsh`, and `--fish` options are only available in fzf 0.48.0 or
> later. If you have an older version of fzf, or want finer control, you can
> source individual script files in the [/shell](/shell) directory. The
> location of the files may vary depending on the package manager you use.
> Please refer to the package documentation for more information.
> (e.g. `apt show fzf`)
> [!TIP]
> You can disable CTRL-T or ALT-C binding by setting `FZF_CTRL_T_COMMAND` or
> `FZF_ALT_C_COMMAND` to an empty string when sourcing the script.
> For example, to disable ALT-C binding:
>
> * bash: `FZF_ALT_C_COMMAND= eval "$(fzf --bash)"`
> * zsh: `FZF_ALT_C_COMMAND= eval "$(fzf --zsh)"`
> * fish: `fzf --fish | FZF_ALT_C_COMMAND= source`
>
> Setting the variables after sourcing the script will have no effect.
### 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 traverse the file system under the current
directory to get the list of files.
```sh
vim $(fzf)
```
> [!NOTE]
> You can override the default behavior
> * Either by setting `$FZF_DEFAULT_COMMAND` to a command that generates the desired list
> * Or by setting `--walker`, `--walker-root`, and `--walker-skip` options in `$FZF_DEFAULT_OPTS`
> [!WARNING]
> 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
> ```
> [!TIP]
> 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. `export FZF_DEFAULT_COMMAND='fd --type f'`
- `FZF_DEFAULT_OPTS`
- Default options
- e.g. `export FZF_DEFAULT_OPTS="--layout=reverse --inline-info"`
- `FZF_DEFAULT_OPTS_FILE`
- If you prefer to manage default options in a file, set this variable to
point to the location of the file
- e.g. `export FZF_DEFAULT_OPTS_FILE=~/.fzfrc`
> [!WARNING]
> `FZF_DEFAULT_COMMAND` is not used by shell integration due to the
> slight difference in requirements.
>
> * `CTRL-T` runs `$FZF_CTRL_T_COMMAND` to get a list of files and directories
> * `ALT-C` runs `$FZF_ALT_C_COMMAND` to get a list of directories
> * `vim ~/**
Examples
--------
* [Wiki page of examples](https://github.com/junegunn/fzf/wiki/examples)
* *Disclaimer: The examples on this page are maintained by the community
and are not thoroughly tested*
* [Advanced fzf examples](https://github.com/junegunn/fzf/blob/master/ADVANCED.md)
`fzf-tmux` script
-----------------
[fzf-tmux](bin/fzf-tmux) is a bash script that opens fzf in a tmux pane.
```sh
# usage: fzf-tmux [LAYOUT OPTIONS] [--] [FZF OPTIONS]
# See available options
fzf-tmux --help
# select git branches in horizontal split below (15 lines)
git branch | fzf-tmux -d 15
# select multiple words in vertical split on the left (20% of screen width)
cat /usr/share/dict/words | fzf-tmux -l 20% --multi --reverse
```
It will still work even when you're not on tmux, silently ignoring `-[pudlr]`
options, so you can invariably use `fzf-tmux` in your scripts.
Alternatively, you can use `--height HEIGHT[%]` option not to start fzf in
fullscreen mode.
```sh
fzf --height 40%
```
Key bindings for command-line
-----------------------------
The install script will setup the following key bindings for bash, zsh, and
fish.
- `CTRL-T` - Paste the selected files and directories onto the command-line
- The list is generated using `--walker file,dir,follow,hidden` option
- You can override the behavior by setting `FZF_CTRL_T_COMMAND` to a custom command that generates the desired list
- Or you can set `--walker*` options in `FZF_CTRL_T_OPTS`
- Set `FZF_CTRL_T_OPTS` to pass additional options to fzf
```sh
# Preview file content using bat (https://github.com/sharkdp/bat)
export FZF_CTRL_T_OPTS="
--walker-skip .git,node_modules,target
--preview 'bat -n --color=always {}'
--bind 'ctrl-/:change-preview-window(down|hidden|)'"
```
- Can be disabled by setting `FZF_CTRL_T_COMMAND` to an empty string when
sourcing the script
- `CTRL-R` - Paste the selected command from history onto the command-line
- If you want to see the commands in chronological order, press `CTRL-R`
again which toggles sorting by relevance
- Set `FZF_CTRL_R_OPTS` to pass additional options to fzf
```sh
# CTRL-/ to toggle small preview window to see the full command
# CTRL-Y to copy the command into clipboard using pbcopy
export FZF_CTRL_R_OPTS="
--preview 'echo {}' --preview-window up:3:hidden:wrap
--bind 'ctrl-/:toggle-preview'
--bind 'ctrl-y:execute-silent(echo -n {2..} | pbcopy)+abort'
--color header:italic
--header 'Press CTRL-Y to copy command into clipboard'"
```
- `ALT-C` - cd into the selected directory
- The list is generated using `--walker dir,follow,hidden` option
- Set `FZF_ALT_C_COMMAND` to override the default command
- Or you can set `--walker-*` options in `FZF_ALT_C_OPTS`
- Set `FZF_ALT_C_OPTS` to pass additional options to fzf
```sh
# Print tree structure in the preview window
export FZF_ALT_C_OPTS="
--walker-skip .git,node_modules,target
--preview 'tree -C {}'"
```
- Can be disabled by setting `FZF_ALT_C_COMMAND` to an empty string when
sourcing the script
If you're on a tmux session, you can start fzf in a tmux split-pane or in
a tmux popup window by setting `FZF_TMUX_OPTS` (e.g. `export FZF_TMUX_OPTS='-p80%,60%'`).
See `fzf-tmux --help` for available options.
More tips can be found on [the wiki page](https://github.com/junegunn/fzf/wiki/Configuring-shell-key-bindings).
Fuzzy completion for bash and zsh
---------------------------------
### Files and directories
Fuzzy completion for files and directories can be triggered if the word before
the cursor ends with the trigger sequence, which is by default `**`.
