[bin]: https://github.com/junegunn/fzf/releases ### Using Homebrew or Linuxbrew You can use [Homebrew](http://brew.sh/) or [Linuxbrew](http://linuxbrew.sh/) to install fzf. ```sh brew install fzf # To install useful key bindings and fuzzy completion: $(brew --prefix)/opt/fzf/install ``` 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 ``` ### Using Linux package managers | Package Manager | Linux Distribution | Command | | --- | --- | --- | | APK | Alpine Linux | `sudo apk add fzf` | | APT | Debian 9+/Ubuntu 19.10+ | `sudo apt-get 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` | | pkg_add | OpenBSD | `pkg_add fzf` | | XBPS | Void Linux | `sudo xbps-install -S fzf` | | Zypper | openSUSE | `sudo zypper install fzf` | > :warning: **Key bindings (CTRL-T / CTRL-R / ALT-C) and fuzzy auto-completion > may not be enabled by default.** > > Refer to the package documentation for more information. (e.g. `apt-cache show fzf`) ### Windows Pre-built binaries for Windows can be downloaded [here][bin]. fzf is also available via [Chocolatey][choco] and [Scoop][scoop]: | Package manager | Command | | --- | --- | | Chocolatey | `choco install fzf` | | Scoop | `scoop install fzf` | [choco]: https://chocolatey.org/packages/fzf [scoop]: https://github.com/ScoopInstaller/Main/blob/master/bucket/fzf.json Known issues and limitations on Windows can be found on [the wiki page][windows-wiki]. [windows-wiki]: https://github.com/junegunn/fzf/wiki/Windows ### 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 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` 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"` #### 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 -------- 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 [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 - 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 tmux split-pane or in a tmux popup window by setting `FZF_TMUX_OPTS` (e.g. `-d 40%`). 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. In this case, there is no trigger sequence; just press the tab key after the 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='+c -x' # Use fd (https://github.com/sharkdp/fd) instead of the default find # command 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" } # (EXPERIMENTAL) 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 "$@" --preview 'dig {}' ;; *) fzf "$@" ;; 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 and is [getting even faster][perf]. Performance should not be a problem in most use cases. However, you might want to be aware of the options that 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 `$FZF_DEFAULT_OPTS`. - `--nth` makes fzf slower because it has to tokenize each line. - `--with-nth` makes fzf slower as fzf has to tokenize and reassemble each line. - If you absolutely need better performance, you can consider using `--algo=v1` (the default being `v2`) to make fzf use a faster greedy algorithm. However, this algorithm is not guaranteed to find the optimal ordering of the matches and is not recommended. [perf]: https://junegunn.kr/images/fzf-0.17.0.png ### Executing external programs You can set up key bindings for starting external processes without leaving fzf (`execute`, `execute-silent`). ```bash # Press F1 to open the file with less without leaving fzf # Press CTRL-Y to copy the line to clipboard and aborts fzf (requires pbcopy) fzf --bind 'f1:execute(less -f {}),ctrl-y:execute-silent(echo {} | pbcopy)+abort' ``` See *KEY BINDINGS* section of the man page for details. ### Reloading the candidate list By binding `reload` action to a key or an event, you can make fzf dynamically reload the candidate list. See https://github.com/junegunn/fzf/issues/1750 for more details. #### 1. Update the list of processes by pressing CTRL-R ```sh FZF_DEFAULT_COMMAND='ps -ef' \ fzf --bind 'ctrl-r:reload($FZF_DEFAULT_COMMAND)' \ --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($FZF_DEFAULT_COMMAND)' \ --height=50% --layout=reverse ``` #### 3. Interactive ripgrep integration The following example uses fzf as the selector interface for ripgrep. We bound `reload` action to `change` event, so every time you type on fzf, the ripgrep process will restart with the updated query string denoted by the placeholder expression `{q}`. Also, note that we used `--phony` option so that fzf doesn't perform any secondary filtering. ```sh INITIAL_QUERY="" RG_PREFIX="rg --column --line-number --no-heading --color=always --smart-case " FZF_DEFAULT_COMMAND="$RG_PREFIX '$INITIAL_QUERY'" \ fzf --bind "change:reload:$RG_PREFIX {q} || true" \ --ansi --phony --query "$INITIAL_QUERY" \ --height=50% --layout=reverse ``` If ripgrep doesn't find any matches, it will exit with a non-zero exit status, and fzf will warn you about it. To suppress the warning message, we added `|| true` to the command, so that it always exits with 0. ### Preview window When the `--preview` option is set, fzf automatically starts an external process with the current line as the argument and shows the result in the split window. Your `$SHELL` is used to execute the command with `$SHELL -c COMMAND`. The window can be scrolled using the mouse or custom key bindings. ```bash # {} is replaced with the single-quoted string of the focused line fzf --preview 'cat {}' ``` Preview window supports ANSI colors, so you can use any program that syntax-highlights the content of a file, such as [Bat](https://github.com/sharkdp/bat) or [Highlight](http://www.andre-simon.de/doku/highlight/en/highlight.php): ```bash fzf --preview 'bat --style=numbers --color=always --line-range :500 {}' ``` You can customize the size, position, and border of the preview window using `--preview-window` option, and the foreground and background color of it with `--color` option. For example, ```bash fzf --height 40% --layout reverse --info inline --border \ --preview 'file {}' --preview-window down:1:noborder \ --color 'fg:#bbccdd,fg+:#ddeeff,bg:#334455,preview-bg:#223344,border:#778899' ``` See the man page (`man fzf`) for the full list of options. For more advanced examples, see [Key bindings for git with fzf][fzf-git] ([code](https://gist.github.com/junegunn/8b572b8d4b5eddd8b85e5f4d40f17236)). [fzf-git]: https://junegunn.kr/2016/07/fzf-git/ ---- Since fzf is a general-purpose text filter rather than a file finder, **it is not a good idea to add `--preview` option to your `$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 ``` 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) instead of the default find command to traverse the file system while respecting `.gitignore`. ```sh # Feed the output of fd into fzf fd --type f | fzf # Setting fd as the default source for fzf export FZF_DEFAULT_COMMAND='fd --type f' # Now fzf (w/o pipe) will use fd instead of find fzf # To apply the command to CTRL-T as well export FZF_CTRL_T_COMMAND="$FZF_DEFAULT_COMMAND" ``` If you want the command to follow symbolic links and don't want it to exclude hidden files, use the following command: ```sh export FZF_DEFAULT_COMMAND='fd --type f --hidden --follow --exclude .git' ``` #### Fish shell `CTRL-T` key binding of fish, unlike those of bash and zsh, will use the last token on the command-line as the root directory for the recursive search. For instance, hitting `CTRL-T` at the end of the following command-line ```sh ls /var/ ``` will list all files and directories under `/var/`. When using a custom `FZF_CTRL_T_COMMAND`, use the unexpanded `$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#^\./##'" ``` Related projects ---------------- https://github.com/junegunn/fzf/wiki/Related-projects [License](LICENSE) ------------------ The MIT License (MIT) Copyright (c) 2013-2021 Junegunn Choi
