fzf is a general-purpose command-line fuzzy finder.
It's an interactive filter program for any kind of list; files, command history, processes, hostnames, bookmarks, git commits, etc. It implements a "fuzzy" matching algorithm, so you can quickly type in patterns with omitted characters and still get the results you want.
Pros
- Portable, no dependencies
- Blazingly fast
- Extremely versatile
- Batteries included
- bash/zsh/fish integration, tmux integration, Vim/Neovim plugin

Installation
Using Homebrew
You can use Homebrew (on macOS or Linux) to install fzf.
brew install fzf
Important
To set up shell integration (key bindings and fuzzy completion), see the instructions below.
fzf is also available via MacPorts: sudo port install fzf
Linux packages
Package Manager | Linux Distribution | Command |
---|---|---|
APK | Alpine Linux | sudo apk add fzf |
APT | Debian 9+/Ubuntu 19.10+ | sudo apt install fzf |
Conda | conda install -c conda-forge fzf |
|
DNF | Fedora | sudo dnf install fzf |
Nix | NixOS, etc. | nix-env -iA nixpkgs.fzf |
Pacman | Arch Linux | sudo pacman -S fzf |
pkg | FreeBSD | pkg install fzf |
pkgin | NetBSD | pkgin install fzf |
pkg_add | OpenBSD | pkg_add fzf |
Portage | Gentoo | emerge --ask app-shells/fzf |
Spack | spack install fzf |
|
XBPS | Void Linux | sudo xbps-install -S fzf |
Zypper | openSUSE | sudo zypper install fzf |
Important
To set up shell integration (key bindings and fuzzy completion), see the instructions below.
Windows packages
On Windows, fzf is available via Chocolatey, Scoop, Winget, and MSYS2:
Package manager | Command |
---|---|
Chocolatey | choco install fzf |
Scoop | scoop install fzf |
Winget | winget install fzf |
MSYS2 (pacman) | pacman -S $MINGW_PACKAGE_PREFIX-fzf |
Using git
Alternatively, you can "git clone" this repository to any directory and run install script.
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
$PATH
and set up shell integration.
Binary releases
You can download the official fzf binaries from the releases page.
Setting up shell integration
Add the following line to your shell configuration file.
- bash
# Set up fzf key bindings and fuzzy completion eval "$(fzf --bash)"
- zsh
# Set up fzf key bindings and fuzzy completion source <(fzf --zsh)
- 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 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
orFZF_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= source <(fzf --zsh)
- fish:
fzf --fish | FZF_ALT_C_COMMAND= source
Setting the variables after sourcing the script will have no effect.
Vim/Neovim plugin
If you use vim-plug, add this to your Vim configuration file:
Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
Plug 'junegunn/fzf.vim'
junegunn/fzf
provides the basic library functionsfzf#install()
makes sure that you have the latest binary
junegunn/fzf.vim
is a separate project that provides a variety of useful commands
To learn more about the Vim integration, see README-VIM.md.
Tip
If you use Neovim and prefer Lua-based plugins, check out fzf-lua.
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.
Usage
fzf will launch interactive finder, read the list from STDIN, and write the selected item to STDOUT.
find * -type f | fzf > selected
Without STDIN pipe, fzf will traverse the file system under the current directory to get the list of files.
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 graspfzf --print0 | xargs -0 -o vim
Tip
fzf also has the ability to turn itself into a different process.
fzf --bind 'enter:become(vim {})'
See Turning into a different process for more information.
Using the finder
CTRL-K
/CTRL-J
(orCTRL-P
/CTRL-N
) to move cursor up and downEnter

/CTRL-G
/ESC
to exit- On multi-select mode (
-m
),TAB
andShift-TAB
to mark multiple items - Emacs style key bindings
- Mouse: scroll, click, double-click; shift-click and shift-scroll on multi-select mode
Display modes
fzf by default runs in fullscreen mode, but there are other display modes.
--height
mode
With --height HEIGHT[%]
, fzf will start below the cursor with the given height.
fzf --height 40%
reverse
layout and --border
goes well with this option.
fzf --height 40% --layout reverse --border
By prepending ~
to the height, you're setting the maximum height.
# Will take as few lines as possible to display the list
seq 3 | fzf --height ~100%
seq 3000 | fzf --height ~100%
Height value can be a negative number.
# Screen height - 3
fzf --height -3
--tmux
mode
With --tmux
option, fzf will start in a tmux popup.
# --tmux [center|top|bottom|left|right][,SIZE[%]][,SIZE[%]]
fzf --tmux center # Center, 50% width and height
fzf --tmux 80% # Center, 80% width and height
fzf --tmux 100%,50% # Center, 100% width and 50% height
fzf --tmux left,40% # Left, 40% width
fzf --tmux left,40%,90% # Left, 40% width, 90% height
fzf --tmux top,40% # Top, 40% height
fzf --tmux bottom,80%,40% # Bottom, 80% height, 40% height
--tmux
is silently ignored when you're not on tmux.
Note
If you're stuck with an old version of tmux that doesn't support popup, or if you want to open fzf in a regular tmux pane, check out fzf-tmux script.
Tip
You can add these options to
$FZF_DEFAULT_OPTS
so that they're applied by default. For example,# Open in tmux popup if on tmux, otherwise use --height mode export FZF_DEFAULT_OPTS='--height 40% --tmux bottom,40% --layout reverse --border top'
Search syntax
Unless otherwise specified, fzf starts in "extended-search mode" where you can
type in multiple search terms delimited by spaces. e.g. ^music .mp3$ sbtrkt !fire
Token | Match type | Description |
---|---|---|
sbtrkt |
fuzzy-match | Items that match sbtrkt |
'wild |
exact-match (quoted) | Items that include wild |
'wild' |
exact-boundary-match (quoted both ends) | Items that include wild at word boundaries |
^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.

Key bindings for command-line
By setting up shell integration, you can use the following key bindings in 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 inFZF_CTRL_T_OPTS
- You can override the behavior by setting
- Set
FZF_CTRL_T_OPTS
to pass additional options to fzf# 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
- The list is generated using
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 - Press
CTRL-/
orALT-/
to toggle line wrapping - Set
FZF_CTRL_R_OPTS
to pass additional options to fzf# CTRL-Y to copy the command into clipboard using pbcopy export FZF_CTRL_R_OPTS=" --bind 'ctrl-y:execute-silent(echo -n {2..} | pbcopy)+abort' --color header:italic --header 'Press CTRL-Y to copy command into clipboard'"
- If you want to see the commands in chronological order, press
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 inFZF_ALT_C_OPTS
- Or you can set
- Set
FZF_ALT_C_OPTS
to pass additional options to fzf# 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
- The list is generated using
Display modes for these bindings can be separately configured via
FZF_{CTRL_T,CTRL_R,ALT_C}_OPTS
or globally via FZF_DEFAULT_OPTS
.
(e.g. FZF_CTRL_R_OPTS='--tmux bottom,60% --height 60% --border top'
)

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]**<TAB>
# Files under the current directory
# - You can select multiple items with TAB key
vim **<TAB>
# Files under parent directory
vim ../**<TAB>
# Files under parent directory that match `fzf`
vim ../fzf**<TAB>
# Files under your home directory
vim ~/**<TAB>
# Directories under current directory (single-selection)
cd **<TAB>
# Directories under ~/github that match `fzf`
cd ~/github/fzf**<TAB>
Process IDs
Fuzzy completion for PIDs is provided for kill command.
# Can select multiple processes with <TAB> or <Shift-TAB> keys
kill -9 **<TAB>
Host names
For ssh and telnet commands, fuzzy completion for hostnames is provided. The names are extracted from /etc/hosts and ~/.ssh/config.
ssh **<TAB>
telnet **<TAB>
Environment variables / Aliases
unset **<TAB>
export **<TAB>
unalias **<TAB>
Settings
# Use ~~ as the trigger sequence instead of the default **
export FZF_COMPLETION_TRIGGER='~~'
# Options to fzf command
export FZF_COMPLETION_OPTS='--border --info=inline'
# Use fd (https://github.com/sharkdp/fd) for listing path candidates.
# - The first argument to the function ($1) is the base path to start traversal
# - See the source code (completion.{bash,zsh}) for the details.
_fzf_compgen_path() {
fd --hidden --follow --exclude ".git" . "$1"
}
# Use fd to generate the list for directory completion
_fzf_compgen_dir() {
fd --type d --hidden --follow --exclude ".git" . "$1"
}
# Advanced customization of fzf options via _fzf_comprun function
# - The first argument to the function is the name of the command.
# - You should make sure to pass the rest of the arguments to fzf.
_fzf_comprun() {
local command=$1
shift
case "$command" in
cd) fzf --preview 'tree -C {} | head -200' "$@" ;;
export|unset) fzf --preview "eval 'echo \$'{}" "$@" ;;
ssh) fzf --preview 'dig {}' "$@" ;;
*) fzf --preview 'bat -n --color=always {}' "$@" ;;
esac
}
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 by using _fzf_setup_completion
helper function.
# usage: _fzf_setup_completion path|dir|var|alias|host COMMANDS...
_fzf_setup_completion path ag git kubectl
_fzf_setup_completion dir tree
Custom fuzzy completion
(Custom completion API is experimental and subject to change)
For a command named "COMMAND", define _fzf_complete_COMMAND
function using
_fzf_complete
helper.
# Custom fuzzy completion for "doge" command
# e.g. doge **<TAB>
_fzf_complete_doge() {
_fzf_complete --multi --reverse --prompt="doge> " -- "$@" < <(
echo very
echo wow
echo such
echo doge
)
}
- The arguments before
--
are the options to fzf. - After
--
, simply pass the original completion arguments unchanged ("$@"
). - Then, write a set of commands that generates the completion candidates and
feed its output to the function using process substitution (
< <(...)
).
zsh will automatically pick up the function using the naming convention but in
bash you have to manually associate the function with the command using the
complete
command.
[ -n "$BASH" ] && complete -F _fzf_complete_doge -o default -o bashdefault doge
If you need to post-process the output from fzf, define
_fzf_complete_COMMAND_post
as follows.
_fzf_complete_foo() {
_fzf_complete --multi --reverse --header-lines=3 -- "$@" < <(
ls -al
)
}
_fzf_complete_foo_post() {
awk '{print $NF}'
}
[ -n "$BASH" ] && complete -F _fzf_complete_foo -o default -o bashdefault foo
Vim plugin
See README-VIM.md.
Advanced topics
Performance
fzf is fast. Performance should not be a problem in most use cases. However, you might want to be aware of the options that can affect performance.
--ansi
tells fzf to extract and parse ANSI color codes in the input, and it makes the initial scanning slower. So it's not recommended that you add it to your$FZF_DEFAULT_OPTS
.--nth
makes fzf slower because it has to tokenize each line.--with-nth
makes fzf slower as fzf has to tokenize and reassemble each line.
Executing external programs
You can set up key bindings for starting external processes without leaving
fzf (execute
, execute-silent
).
# Press F1 to open the file with less without leaving fzf
# Press CTRL-Y to copy the line to clipboard and aborts fzf (requires pbcopy)
fzf --bind 'f1:execute(less -f {}),ctrl-y:execute-silent(echo {} | pbcopy)+abort'
See KEY BINDINGS section of the man page for details.
Turning into a different process
become(...)
is similar to execute(...)
/execute-silent(...)
described
above, but instead of executing the command and coming back to fzf on
complete, it turns fzf into a new process for the command.
fzf --bind 'enter:become(vim {})'
Compared to the seemingly equivalent command substitution vim "$(fzf)"
, this
approach has several advantages:
- Vim will not open an empty file when you terminate fzf with CTRL-C
- Vim will not open an empty file when you press ENTER on an empty result
- Can handle multiple selections even when they have whitespaces
fzf --multi --bind 'enter:become(vim {+})'
To be fair, running fzf --print0 | xargs -0 -o vim
instead of vim "$(fzf)"
resolves all of the issues mentioned. Nonetheless, become(...)
still offers
additional benefits in different scenarios.
- You can set up multiple bindings to handle the result in different ways
without any wrapping script
fzf --bind 'enter:become(vim {}),ctrl-e:become(emacs {})'
- Previously, you would have to use
--expect=ctrl-e
and check the first line of the output of fzf
- Previously, you would have to use
- You can easily build the subsequent command using the field index
expressions of fzf
# Open the file in Vim and go to the line git grep --line-number . | fzf --delimiter : --nth 3.. --bind 'enter:become(vim {1} +{2})'
Reloading the candidate list
By binding reload
action to a key or an event, you can make fzf dynamically
reload the candidate list. See https://github.com/junegunn/fzf/issues/1750 for
more details.
1. Update the list of processes by pressing CTRL-R
ps -ef |
fzf --bind 'ctrl-r:reload(ps -ef)' \
--header 'Press CTRL-R to reload' --header-lines=1 \
--height=50% --layout=reverse
2. Switch between sources by pressing CTRL-D or CTRL-F
FZF_DEFAULT_COMMAND='find . -type f' \
fzf --bind 'ctrl-d:reload(find . -type d),ctrl-f:reload(eval "$FZF_DEFAULT_COMMAND")' \
--height=50% --layout=reverse
3. Interactive ripgrep integration
The following example uses fzf as the selector interface for ripgrep. We bound
reload
action to change
event, so every time you type on fzf, the ripgrep
process will restart with the updated query string denoted by the placeholder
expression {q}
. Also, note that we used --disabled
option so that fzf
doesn't perform any secondary filtering.
: | rg_prefix='rg --column --line-number --no-heading --color=always --smart-case' \
fzf --bind 'start:reload:$rg_prefix ""' \
--bind 'change:reload:$rg_prefix {q} || true' \
--bind 'enter:become(vim {1} +{2})' \
--ansi --disabled \
--height=50% --layout=reverse
If ripgrep doesn't find any matches, it will exit with a non-zero exit status,
and fzf will warn you about it. To suppress the warning message, we added
|| true
to the command, so that it always exits with 0.
See "Using fzf as interactive Ripgrep launcher" for more sophisticated examples.
Preview window
When the --preview
option is set, fzf automatically starts an external process
with the current line as the argument and shows the result in the split window.
Your $SHELL
is used to execute the command with $SHELL -c COMMAND
.
The window can be scrolled using the mouse or custom key bindings.
# {} is replaced with the single-quoted string of the focused line
fzf --preview 'cat {}'
Preview window supports ANSI colors, so you can use any program that syntax-highlights the content of a file, such as Bat or Highlight:
fzf --preview 'bat --color=always {}' --preview-window '~3'
You can customize the size, position, and border of the preview window using
--preview-window
option, and the foreground and background color of it with
--color
option. For example,
fzf --height 40% --layout reverse --info inline --border \
--preview 'file {}' --preview-window up,1,border-horizontal \
--bind 'ctrl-/:change-preview-window(50%|hidden|)' \
--color 'fg:#bbccdd,fg+:#ddeeff,bg:#334455,preview-bg:#223344,border:#778899'
See the man page (man fzf
) for the full list of options.
More advanced examples can be found here.
Warning
Since fzf is a general-purpose text filter rather than a file finder, it is not a good idea to add
--preview
option to your$FZF_DEFAULT_OPTS
.# ********************* # ** DO NOT DO THIS! ** # ********************* export FZF_DEFAULT_OPTS='--preview "bat --style=numbers --color=always --line-range :500 {}"' # bat doesn't work with any input other than the list of files ps -ef | fzf seq 100 | fzf history | fzf
Previewing an image
fzf can display images in the preview window using one of the following protocols:
See bin/fzf-preview.sh script for more information.
fzf --preview 'fzf-preview.sh {}'
Tips
Respecting .gitignore
You can use fd,
ripgrep, or the silver
searcher to traverse the file
system while respecting .gitignore
.
# Feed the output of fd into fzf
fd --type f --strip-cwd-prefix | fzf
# Setting fd as the default source for fzf
export FZF_DEFAULT_COMMAND='fd --type f --strip-cwd-prefix'
# Now fzf (w/o pipe) will use the fd command to generate the list
fzf
# To apply the command to CTRL-T as well
export FZF_CTRL_T_COMMAND="$FZF_DEFAULT_COMMAND"
If you want the command to follow symbolic links and don't want it to exclude hidden files, use the following command:
export FZF_DEFAULT_COMMAND='fd --type f --strip-cwd-prefix --hidden --follow --exclude .git'
Fish shell
CTRL-T
key binding of fish, unlike those of bash and zsh, will use the last
token on the command-line as the root directory for the recursive search. For
instance, hitting CTRL-T
at the end of the following command-line
ls /var/
will list all files and directories 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:
set -g FZF_CTRL_T_COMMAND "command find -L \$dir -type f 2> /dev/null | sed '1d; s#^\./##'"
