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.
[bin]: https://github.com/junegunn/fzf-bin/releases
### Using git
Clone this repository 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
```
### Using Homebrew
On OS X, you can use [Homebrew](http://brew.sh/) to install fzf.
```sh
brew install fzf
# Install shell extensions
/usr/local/opt/fzf/install
```
### As Vim plugin
You can manually add the directory to `&runtimepath` as follows,
```vim
" If installed using git
set rtp+=~/.fzf
" If installed using Homebrew
set rtp+=/usr/local/opt/fzf
```
But it's recommended that you use a plugin manager like
[vim-plug](https://github.com/junegunn/vim-plug).
```vim
Plug 'junegunn/fzf', { 'dir': '~/.fzf', 'do': './install --all' }
```
### Windows
Pre-built binaries for Windows can be downloaded [here][bin]. fzf is also
available as a [Chocolatey package][choco].
[choco]: https://chocolatey.org/packages/fzf
```sh
choco install fzf
```
However, other components of the project may not work on Windows. You might
want to consider installing fzf on [Windows Subsystem for Linux][wsl] where
everything runs flawlessly.

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 reinstall 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)
```
#### Using the finder
- `CTRL-J` / `CTRL-K` (or `CTRL-N` / `CTRL-P`) 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` option 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% --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` |
| `^music` | prefix-exact-match | Items that start with `music` |
| `.mp3$` | suffix-exact-match | Items that end with `.mp3` |
| `'wild` | exact-match (quoted) | Items that include `wild` |
| `!fire` | inverse-exact-match | Items that do not include `fire` |
| `!.mp3$` | 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='ag -g ""'`
- `FZF_DEFAULT_OPTS`
- Default options
- e.g. `export FZF_DEFAULT_OPTS="--reverse --inline-info"`
#### Options
See the man page (`man fzf`) for the full list of options.
Examples
--------
Many useful examples can be found on [the wiki
page](https://github.com/junegunn/fzf/wiki/examples). Feel free to add your
own as well.
`fzf-tmux` script
-----------------
[fzf-tmux](bin/fzf-tmux) is a bash script that opens fzf in a tmux pane.
```sh
# usage: fzf-tmux [-u|-d [HEIGHT[%]]] [-l|-r [WIDTH[%]]] [--] [FZF OPTIONS]
# (-[udlr]: up/down/left/right)
# 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 `-[udlr]`
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
- Set `FZF_CTRL_T_COMMAND` to override the default command
- Set `FZF_CTRL_T_OPTS` to pass additional options
- `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
- `ALT-C` - cd into the selected directory
- Set `FZF_ALT_C_COMMAND` to override the default command
- Set `FZF_ALT_C_OPTS` to pass additional options
If you're on a tmux session, you can start fzf in a split pane by setting
`FZF_TMUX` to 1, and change the height of the pane with `FZF_TMUX_HEIGHT`
(e.g. `20`, `50%`).
If you use vi mode on bash, you need to add `set -o vi` *before* `source
~/.fzf.bash` in your .bashrc, so that it correctly sets up key bindings for vi
mode.
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 `**`.
- `COMMAND [DIRECTORY/][FUZZY_PATTERN]**`
```sh
# Files under current directory
# - You can select multiple items with TAB key
vim **
# Files under parent directory
vim ../**
# Files under parent directory that match `fzf`
vim ../fzf**
# Files under your home directory
vim ~/**
# Directories under current directory (single-selection)
cd **
# Directories under ~/github that match `fzf`
cd ~/github/fzf**
```
#### Process IDs
Fuzzy completion for PIDs is provided for kill command. In this case
there is no trigger sequence, just press tab key after kill command.
```sh
# Can select multiple processes with or keys
kill -9
```
#### Host names
For ssh and telnet commands, fuzzy completion for host names is provided. The
names are extracted from /etc/hosts and ~/.ssh/config.
```sh
ssh **
telnet **
```
#### Environment variables / Aliases
```sh
unset **
export **
unalias **
```
#### Settings
```sh
# Use ~~ as the trigger sequence instead of the default **
export FZF_COMPLETION_TRIGGER='~~'
# Options to fzf command
export FZF_COMPLETION_OPTS='+c -x'
# Use ag instead of the default find command for listing candidates.
# - The first argument to the function is the base path to start traversal
# - Note that ag only lists files not directories
# - See the source code (completion.{bash,zsh}) for the details.
_fzf_compgen_path() {
ag -g "" "$1"
}
```
#### Supported commands
On bash, fuzzy completion is enabled only for a predefined set of commands
(`complete | grep _fzf` to see the list). But you can enable it for other
commands as well like follows.
```sh
# There are also _fzf_path_completion and _fzf_dir_completion
complete -F _fzf_file_completion -o default -o bashdefault doge
```
Vim plugin
----------
See [README-VIM.md](README-VIM.md).
Tips
----
#### Respecting `.gitignore`, `.hgignore`, and `svn:ignore`
[ag](https://github.com/ggreer/the_silver_searcher) or
[pt](https://github.com/monochromegane/the_platinum_searcher) will do the
filtering:
```sh
# Feed the output of ag into fzf
ag -g "" | fzf
# Setting ag as the default source for fzf
export FZF_DEFAULT_COMMAND='ag -g ""'
# Now fzf (w/o pipe) will use ag instead of find
fzf
# To apply the command to CTRL-T as well
export FZF_CTRL_T_COMMAND="$FZF_DEFAULT_COMMAND"
```
If you don't want to exclude hidden files, use the following command:
```sh
export FZF_DEFAULT_COMMAND='ag --hidden --ignore .git -g ""'
```
#### `git ls-tree` for fast traversal
If you're running fzf in a large git repository, `git ls-tree` can boost up the
speed of the traversal.
```sh
export FZF_DEFAULT_COMMAND='
(git ls-tree -r --name-only HEAD ||
find . -path "*/\.*" -prune -o -type f -print -o -type l -print |
sed s/^..//) 2> /dev/null'
```
#### Fish shell
It's [a known bug of fish](https://github.com/fish-shell/fish-shell/issues/1362)
(will be fixed in 2.6.0) that it doesn't allow reading from STDIN in command
substitution, which means simple `vim (fzf)` won't work as expected. The
workaround is to use the `read` fish command:
```sh
fzf | read -l result; and vim $result
```
or, for multiple results:
```sh
fzf -m | while read -l r; set result $result $r; end; and vim $result
```
The globbing system is different in fish and thus `**` completion will not work.
However, the `CTRL-T` command will use the last token on the commandline as the
root folder for the recursive search. For instance, hitting `CTRL-T` at the end
of the following commandline
```sh
ls /var/
```
will list all files and folders under `/var/`.
When using a custom `FZF_CTRL_T_COMMAND`, use the unexpanded `$dir` variable to
make use of this feature. `$dir` defaults to `.` when the last token is not a
valid directory. Example:
```sh
set -l FZF_CTRL_T_COMMAND "command find -L \$dir -type f 2> /dev/null | sed '1d; s#^\./##'"
