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.

• https://github.com/junegunn/fzf/releases

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

script generates a file in the autoload directory. If you didn't use the install script, you can manually set it up:

• Nushell -- Nushell does not support piping into source , so the install

Generate the integration script

mkdir ( $nu . default - config - dir | path join " autoload " )

fzf -- nushell | save - f ( $nu . default - config - dir | path join " autoload " " _fzf_integration.nu " )

Note --bash , --zsh , --fish , and --nushell options are only available in recent versions of fzf. 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, CTRL-R, or ALT-C bindings by setting the corresponding *_COMMAND variable to an empty string when sourcing the script. For example, to disable CTRL-R and ALT-C:

• bash: FZF_CTRL_R_COMMAND= FZF_ALT_C_COMMAND= eval "$(fzf --bash)"

• zsh: FZF_CTRL_R_COMMAND= FZF_ALT_C_COMMAND= source <(fzf --zsh)

• fish: fzf --fish | FZF_CTRL_R_COMMAND= FZF_ALT_C_COMMAND= source

$env.FZF_CTRL_R_COMMAND = ""; $env.FZF_ALT_C_COMMAND = ""

• nushell: add to your env.nu :

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 functions

• fzf#install() makes sure that you have the latest binary

that provides a variety of useful commands

• junegunn/fzf.vim is a separate project

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 grasp

fzf --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 (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

multi-select mode

• Mouse: scroll, click, double-click; shift-click and shift-scroll on

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

--popup mode

With --popup option, fzf will start in a popup window (requires tmux 3.3+ or Zellij 0.44+).

--popup [center|top|bottom|left|right][,SIZE[%]][,SIZE[%][,border-native]]

fzf --popup center # Center, 50% width and height fzf --popup 80% # Center, 80% width and height fzf --popup 100%,50% # Center, 100% width and 50% height fzf --popup left,40% # Left, 40% width fzf --popup left,40%,90% # Left, 40% width, 90% height fzf --popup top,40% # Top, 40% height fzf --popup bottom,80%,40% # Bottom, 80% width, 40% height

--popup is silently ignored when you're not on tmux or Zellij.

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 a popup if on tmux or Zellij, otherwise use --height mode

export FZF_DEFAULT_OPTS= ' --height 40% --popup 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

point to the location of the file

• If you prefer to manage default options in a file, set this variable to

• 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 ~/**<tab> runs fzf_compgen_path() with the prefix ( ~/ ) as the first argument

cd foo**<tab> runs fzf_compgen_dir() with the prefix ( foo ) as the first argument

The available options are described later in this document.

Customizing the look

The user interface of fzf is fully customizable with a large number of configuration options. For a quick setup, you can start with one of the style presets -- default , full , or minimal -- using the --style option.

fzf --style full \ --preview ' fzf-preview.sh {} ' --bind ' focus:transform-header:file --brief {} '

Preset Screenshot

default

full

minimal

Here's an example based on the full preset:

Details

git ls-files | fzf --style full \

--border --padding 1,2 \ --border-label ' Demo ' --input-label ' Input ' --header-label ' File Type ' \ --preview ' fzf-preview.

sh {} ' \ --bind ' result:transform-list-label: if [[ -z $FZF_QUERY ]]; then echo " $FZF_MATCH_COUNT items " else echo " $FZF_MATCH_COUNT matches for [$FZF_QUERY] " fi ' \ --bind ' focus:transform-preview-label:[[ -n {} ]] && printf " Previewing [%s] " {} ' \ --bind ' focus:+transform-header:file --brief {} || echo "No file selected" ' \ --bind ' ctrl-r:change-list-label( Reloading the list )+reload(sleep 2; git ls-files) ' \ --color ' border:#aaaaaa,label:#cccccc ' \ --color ' preview-border:#9999cc,preview-label:#ccccff ' \ --color ' list-border:#669966,list-label:#99cc99 ' \ --color ' input-border:#996666,input-label:#ffcccc ' \ --color ' header-border:#6699cc,header-label:#99ccff '

Key bindings for command-line

By setting up shell integration , you can use the following key bindings in bash, zsh, fish, and Nushell.

• 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

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|)' "

sourcing the script

• Can be disabled by setting FZF_CTRL_T_COMMAND to an empty string when

• CTRL-R - Paste the selected command from history onto the command-line.

• Select multiple commands with TAB .

• If you want to see the commands in chronological order, press CTRL-R

of a match. In this mode, you can press CTRL-N and CTRL-P to move between the matching items only.

• Press ALT-R to toggle "raw" mode where you can see the surrounding items

• Press CTRL-/ or ALT-/ to toggle line wrapping

• Press SHIFT-DELETE to delete the selected commands (bash and fish)

• Fish shell only:

• Press ALT-ENTER to reformat and insert the selected commands

• Press ALT-T to cycle through command prefix (timestamp, date/time, none)

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' "

Fish shell: Set date/time as default prefix

set -gx FZF_CTRL_R_OPTS " --with-nth 1,3.. --bind 'alt-t:change-with-nth(2..|3..|1,3..)' "

Or display no prefix by default

set -gx FZF_CTRL_R_OPTS " --with-nth 3.. --bind 'alt-t:change-with-nth(2..|1,3..|3..)' "

sourcing the script

• Can be disabled by setting FZF_CTRL_R_COMMAND to an empty string when

• Custom override via a non-empty FZF_CTRL_R_COMMAND is not yet supported and will emit a warning

• 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

Print tree structure in the preview window

export FZF_ALT_C_OPTS= "

--walker-skip .git,node_modules,target --preview 'tree -C {}' "

sourcing the script

• Can be disabled by setting FZF_ALT_C_COMMAND to an empty string when

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='--popup bottom,60% --height 60% --border top' )

More tips can be found on the wiki page .

Fuzzy completion

Shell integration also provides fuzzy completion for bash, zsh, fish, and Nushell.

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 command, fuzzy completion for hostnames is provided. The names are extracted from /etc/hosts and ~/.ssh/config.

ssh ** < TAB >

Environment variables / Aliases

bash and zsh

unset ** < TAB >

export ** < TAB >

unalias ** < TAB >

fish

set < SHIFT-TAB >

Customizing fuzzy completion for bash and zsh

Customizing fzf options for completion

Use ~~ as the trigger sequence instead of the default **

export FZF_COMPLETION_TRIGGER= ' ~~ '

Options to fzf command

export FZF_COMPLETION_OPTS= ' --border --info=inline '

Options for path completion (e.g. vim **<TAB>)

export FZF_COMPLETION_PATH_OPTS= ' --walker file,dir,follow,hidden '

Options for directory completion (e.g. cd **<TAB>)

export FZF_COMPLETION_DIR_OPTS= ' --walker dir,follow '

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 {} ' " $@ " ;;

esac }

• ) fzf --preview ' bat -n --color=always {} ' " $@ " ;;

Customizing completion source for paths and directories

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 " }

Supported commands (bash)

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 ( "$@" ).

feed its output to the function using process substitution ( < <(...) ).

• Then, write a set of commands that generates the completion candidates and

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

Fuzzy completion for fish

Fuzzy completion for fish differs from bash and zsh in that:

on Shift-TAB (replacing the native pager search mode), while TAB preserves fish's native completion behavior.

• It doesn't require a trigger sequence like ** . Instead, if activates

rather than performing a recursive file system traversal. For recursive searching, use the CTRL-T binding instead.

• It relies on fish's native completion system to populate the candidate list,

the wildcard expansion path list (instead of the native behavior of inserting all the results in command line). Because the shell is used for the expansion, there is a limit in the number of results.

• If the current command line token is a wildcard pattern, it performs search on

FZF_EXPANSION_OPS .

• The only supported configuration variables are FZF_COMPLETION_OPTS and

fzf_complete , which only accepts fzf options as arguments, and can be also called without any redirected input, to just modify fzf options while presenting the native completion results.

For compatibility with other shells, a function named _fzf_complete is provided, that can accept -- $argv in its command line arguments, after fzf options.

• The function that is used by custom completion functions is named

For commands that are not covered by fish completions, it is better to create regular fish completion functions (which will work for both TAB and Shift-TAB ), and create fzf completion functions only when needing to modify fzf options for a specific command or want different results for Shift-TAB :

Customize git completion

function _fzf_complete_git

Show header text with active branch for all git completions

set -lx -- FZF_COMPLETION_OPTS --header = " ' " (git branch --show-current 2> /dev/null) " ' "

No other changes when less than 3 arguments, or when completing options

if not set -q argv[3]; or string match -q -- ' -* ' $argv [-1] fzf_complete return end

Check subcommand

switch $argv [2] case checkout diff log show

Set preview and display all branches and commits for subcommands: checkout, diff, log, show

begin

git branch --all --format = ' %(refname:short) '

git log --all --oneline --color =always

end | fzf_complete --no-multi --ansi --accept-nth =1 --query = $argv [-1] --preview = ' git show --color=always {1} '

case add rm mv

Only set preview for subcommands: add, rm, mv

Special characters in fish completion lists are escaped, so the r flag must be used.

fzf_complete --preview = " git diff --color=always {r1} "

case ' * '

No changes for other subcommands

fzf_complete end end

Similar to bash and zsh, the output of fzf can be processed before inserted in command line, by defining a function named _fzf_complete_COMMAND_post or _fzf_post_complete_COMMAND :

function _fzf_complete_foo ls -sh --zero --color =always | fzf_complete --read0 --print0 --ansi --no-multi-line --header-lines =1 end

function _fzf_post_complete_foo while read -lz result string escape -n -- $result | string trim -l -c ' \ ' | string split -m 1 -f 2 ' ' end end

Fuzzy completion for Nushell

Fuzzy completion in Nushell works via the external completer mechanism. There are some differences compared to bash and zsh:

built-in commands (e.g. cd , ls ). Fuzzy completion with **<TAB> only works for external commands.

• On Nushell >= 0.103.0, the external completer is no longer called for

your config.nu . Each entry is a closure that receives the prefix and the command spans, and returns either a list of candidate strings or a record { candidates: [.], opts: [.] } for custom fzf options: $env .

FZF_COMPLETERS = { pacman: { | prefix , spans | let sub = $spans | skip 1 | first let candidates = ( if ( $sub = ~ " -[SF] " ) { ^pacman - Slq | lines } else if ( $sub = ~ " -[QR] " ) { ^pacman - Qq | lines } else { [] }) { candidates: $candidates , opts: [ " --preview " , " pacman -Si {} " ] } } }

• Custom completers can be defined via the $env.FZF_COMPLETERS record in

See shell/completion-examples.nu for more examples.

FZF_COMPLETION_TRIGGER , FZF_COMPLETION_OPTS , FZF_COMPLETION_PATH_OPTS , FZF_COMPLETION_DIR_OPTS , FZF_COMPLETION_DIR_COMMANDS .

• The following environment variables are supported:

Customizing for different types of input

Since fzf is a general-purpose text filter, its algorithm was designed to "generally" work well with any kind of input.

However, admittedly, there is no true one-size-fits-all solution, and you may want to tweak the algorithm and some of the settings depending on the type of the input. To make this process easier, fzf provides a set of "scheme"s for some common input types.

Scheme Description

--scheme=default Generic scheme designed to work well with any kind of input

--scheme=path Suitable for file paths

--scheme=history Suitable for command history or any input where chronological ordering is important

(See fzf --man for the details)

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.

makes the initial scanning slower. So it's not recommended that you add it to your $FZF_DEFAULT_OPTS .

• --ansi tells fzf to extract and parse ANSI color codes in the input, and it

• --nth makes fzf slower because it has to tokenize each line.

delimiter.

• A plain string --delimiter should be preferred over a regular expression

line.

• --with-nth makes fzf slower as fzf has to tokenize and reassemble each

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/EVENT 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:

CTRL-C

• Vim will not open an empty file when you terminate fzf with

result

• Vim will not open an empty file when you press ENTER on an empty

fzf --multi --bind ' enter:become(vim {+}) '

• Can handle multiple selections even when they have whitespaces

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.

without any wrapping script fzf --bind ' enter:become(vim {}),ctrl-e:become(emacs {}) '

• You can set up multiple bindings to handle the result in different ways

line of the output of fzf

• Previously, you would have to use --expect=ctrl-e and check the first

expressions of fzf

• You can easily build the subsequent command using the field index

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 #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

1. 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

1. 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
