[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 ``` > [!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. ### Using Linux package managers | 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](#setting-up-shell-integration). [![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], [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 "$(fzf --zsh)" ``` * fish ```fish # Set up fzf key bindings fzf --fish | source ``` > [!NOTE] > `--bash`, `--zsh`, and `--fish` options are only available in > fzf 0.48.0 or above. If you have an older version of fzf, refer to the > package documentation for more information. (e.g. `apt show fzf`) > [!TIP] > You can disable CTRL-T or ALT-C binding by setting `FZF_CTRL_T_COMMAND` or > `FZF_ALT_C_COMMAND` to an empty string when sourcing the script. > For example, to disable ALT-C binding: > * bash: `FZF_ALT_C_COMMAND= eval "$(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 ~/**` runs `fzf_compgen_path()` with the prefix (`~/`) as the first argument > * `cd foo**` runs `fzf_compgen_dir()` with the prefix (`foo`) as the first argument > > The available options are described later in this document. ### Options See the man page (`man fzf`) for the full list of options. ### Demo If you learn by watching videos, check out this screencast by [@samoshkin](https://github.com/samoshkin) to explore `fzf` features. 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 `**`. - `COMMAND [DIRECTORY/][FUZZY_PATTERN]**` ```sh # Files under the 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. ```sh # Can select multiple processes with or keys kill -9 ** ``` ### Host names For ssh and telnet commands, fuzzy completion for hostnames 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='--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. ```sh # 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. ```sh # Custom fuzzy completion for "doge" command # e.g. doge ** _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. ```sh [ -n "$BASH" ] && complete -F _fzf_complete_doge -o default -o bashdefault doge ``` If you need to post-process the output from fzf, define `_fzf_complete_COMMAND_post` as follows. ```sh _fzf_complete_foo() { _fzf_complete --multi --reverse --header-lines=3 -- "$@" < <( 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](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 `$FZF_DEFAULT_OPTS`. - `--nth` makes fzf slower because it has to tokenize each line. - `--with-nth` makes fzf slower as fzf has to tokenize and reassemble each line. ### Executing external programs You can set up key bindings for starting external processes without leaving fzf (`execute`, `execute-silent`). ```bash # Press F1 to open the file with less without leaving fzf # Press CTRL-Y to copy the line to clipboard and aborts fzf (requires pbcopy) fzf --bind 'f1:execute(less -f {}),ctrl-y:execute-silent(echo {} | pbcopy)+abort' ``` See *KEY BINDINGS* section of the man page for details. ### Turning into a different process `become(...)` is similar to `execute(...)`/`execute-silent(...)` described above, but instead of executing the command and coming back to fzf on complete, it turns fzf into a new process for the command. ```sh fzf --bind 'enter:become(vim {})' ``` Compared to the seemingly equivalent command substitution `vim "$(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 ```sh fzf --multi --bind 'enter:become(vim {+})' ``` To be fair, running `fzf --print0 | xargs -0 -o vim` instead of `vim "$(fzf)"` resolves all of the issues mentioned. Nonetheless, `become(...)` still offers additional benefits in different scenarios. * You can set up multiple bindings to handle the result in different ways without any wrapping script ```sh fzf --bind 'enter:become(vim {}),ctrl-e:become(emacs {})' ``` * Previously, you would have to use `--expect=ctrl-e` and check the first line of the output of fzf * You can easily build the subsequent command using the field index expressions of fzf ```sh # Open the file in Vim and go to the line git grep --line-number . | fzf --delimiter : --nth 3.. --bind 'enter:become(vim {1} +{2})' ``` ### Reloading the candidate list By binding `reload` action to a key or an event, you can make fzf dynamically reload the candidate list. See https://github.com/junegunn/fzf/issues/1750 for more details. #### 1. Update the list of processes by pressing CTRL-R ```sh ps -ef | fzf --bind 'ctrl-r:reload(ps -ef)' \ --header 'Press CTRL-R to reload' --header-lines=1 \ --height=50% --layout=reverse ``` #### 2. Switch between sources by pressing CTRL-D or CTRL-F ```sh FZF_DEFAULT_COMMAND='find . -type f' \ fzf --bind 'ctrl-d:reload(find . -type d),ctrl-f:reload(eval "$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. ```sh : | 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"](https://github.com/junegunn/fzf/blob/master/ADVANCED.md#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. ```bash # {} 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](https://github.com/sharkdp/bat) or [Highlight](https://gitlab.com/saalen/highlight): ```bash 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, ```bash 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](https://github.com/junegunn/fzf/blob/master/ADVANCED.md). > [!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 `$FZF_DEFAULT_OPTS`**. > > ```sh > # ********************* > # ** DO NOT DO THIS! ** > # ********************* > export FZF_DEFAULT_OPTS='--preview "bat --style=numbers --color=always --line-range :500 {}"' > > # bat doesn't work with any input other than the list of files > ps -ef | fzf > seq 100 | fzf > history | fzf > ``` ### Previewing an image fzf can display images in the preview window using one of the following protocols: * [Kitty graphics protocol](https://sw.kovidgoyal.net/kitty/graphics-protocol/) * [iTerm2 inline images protocol](https://iterm2.com/documentation-images.html) * [Sixel](https://en.wikipedia.org/wiki/Sixel) See [bin/fzf-preview.sh](bin/fzf-preview.sh) script for more information. ```sh fzf --preview 'fzf-preview.sh {}' ``` Tips ---- ### Respecting `.gitignore` You can use [fd](https://github.com/sharkdp/fd), [ripgrep](https://github.com/BurntSushi/ripgrep), or [the silver searcher](https://github.com/ggreer/the_silver_searcher) to traverse the file system while respecting `.gitignore`. ```sh # Feed the output of fd into fzf fd --type f --strip-cwd-prefix | fzf # Setting fd as the default source for fzf export FZF_DEFAULT_COMMAND='fd --type f --strip-cwd-prefix' # Now fzf (w/o pipe) will use the fd command to generate the list fzf # To apply the command to CTRL-T as well export FZF_CTRL_T_COMMAND="$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: ```sh 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 ```sh 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: ```sh set -g FZF_CTRL_T_COMMAND "command find -L \$dir -type f 2> /dev/null | sed '1d; s#^\./##'" ``` ### fzf Theme Playground [fzf Theme Playground](https://vitormv.github.io/fzf-themes/) created by [Vitor Mello](https://github.com/vitormv) is a webpage where you can interactively create fzf themes.
