[](https://travis-ci.org/junegunn/fzf) === fzf is a general-purpose command-line fuzzy finder.  Pros ---- - No dependency - Blazingly fast - e.g. `locate / | fzf` - Flexible layout - Runs in fullscreen or in horizontal/vertical split using tmux - The most comprehensive feature set - Try `fzf --help` and be surprised - Batteries included - Vim/Neovim plugin, key bindings and fuzzy auto-completion Installation ------------ fzf project consists of the followings: - `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 only) - Vim/Neovim plugin You can [download fzf executable][bin] alone, but it's recommended that you install the extra stuff using the attached install script. [bin]: https://github.com/junegunn/fzf-bin/releases #### Using git (recommended) 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 curl In case you don't have git installed: ```sh mkdir -p ~/.fzf curl -L https://github.com/junegunn/fzf/archive/master.tar.gz | tar xz --strip-components 1 -C ~/.fzf ~/.fzf/install ``` #### Using Homebrew On OS X, you can use [Homebrew](http://brew.sh/) to install fzf. ```sh brew reinstall --HEAD fzf # Install shell extensions /usr/local/Cellar/fzf/HEAD/install ``` #### Install as Vim plugin Once you have cloned the repository, add the following line to your .vimrc. ```vim set rtp+=~/.fzf ``` Or you can have [vim-plug](https://github.com/junegunn/vim-plug) manage fzf (recommended): ```vim Plug 'junegunn/fzf', { 'dir': '~/.fzf', 'do': 'yes \| ./install' } ``` #### 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. - git: `cd ~/.fzf && git pull && ./install` - brew: `brew reinstall --HEAD fzf` - vim-plug: `:PlugUpdate fzf` Usage ----- fzf will launch curses-based 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 $(fzf) ``` #### Using the finder - `CTRL-J` / `CTRL-K` (or `CTRL-N` / `CTRL-P)` to move cursor up and down - `Enter` key to select the item, `CTRL-C` / `CTRL-G` / `ESC` to exit - On multi-select mode (`-m`), `TAB` and `Shift-TAB` to mark multiple items - Emacs style key bindings - Mouse: scroll, click, double-click; shift-click and shift-scroll on multi-select mode #### Extended-search mode With `-x` or `--extended` option, fzf will start in "extended-search mode". In this mode, you can specify multiple patterns delimited by spaces, such as: `^music .mp3$ sbtrkt !rmx` | Token | Description | Match type | | -------- | -------------------------------- | -------------------- | | `^music` | Items that start with `music` | prefix-exact-match | | `.mp3$` | Items that end with `.mp3` | suffix-exact-match | | `sbtrkt` | Items that match `sbtrkt` | fuzzy-match | | `!rmx` | Items that do not match `rmx` | inverse-fuzzy-match | | `'wild` | Items that include `wild` | exact-match (quoted) | | `!'fire` | Items that do not include `fire` | inverse-exact-match | If you don't need fuzzy matching and do not wish to "quote" every word, start fzf with `-e` or `--extended-exact` option. 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. Key bindings for command line ----------------------------- The install script will setup the following key bindings for bash, zsh, and fish. - `CTRL-T` - Paste the selected file path(s) into the command line - `CTRL-R` - Paste the selected command from history into the command line - Sort is disabled by default to respect chronological ordering - Press `CTRL-R` again to toggle sort - `ALT-C` - cd into the selected directory If you're on a tmux session, `CTRL-T` will launch fzf in a new split-window. You may disable this tmux integration by setting `FZF_TMUX` to 0, or change the height of the window 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. If you want to customize the key bindings, consider editing the installer-generated source code: `~/.fzf.bash`, `~/.fzf.zsh`, and `~/.config/fish/functions/fzf_key_bindings.fish`. `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. Fuzzy completion for bash ------------------------- #### 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' ``` Usage as Vim plugin ------------------- (Note: To use fzf in GVim, an external terminal emulator is required.) #### `:FZF[!]` If you have set up fzf for Vim, `:FZF` command will be added. ```vim " Look for files under current directory :FZF " Look for files under your home directory :FZF ~ " With options :FZF --no-sort -m /tmp " Bang version starts in fullscreen instead of using tmux pane or Neovim split :FZF! ``` Similarly to [ctrlp.vim](https://github.com/kien/ctrlp.vim), use enter key, `CTRL-T`, `CTRL-X` or `CTRL-V` to open selected files in the current window, in new tabs, in horizontal splits, or in vertical splits respectively. Note that the environment variables `FZF_DEFAULT_COMMAND` and `FZF_DEFAULT_OPTS` also apply here. #### `fzf#run([options])` For more advanced uses, you can call `fzf#run()` function which returns the list of the selected items. `fzf#run()` may take an options-dictionary: | Option name | Type | Description | | -------------------------- | ------------- | ---------------------------------------------------------------- | | `source` | string | External command to generate input to fzf (e.g. `find .`) | | `source` | list | Vim list as input to fzf | | `sink` | string | Vim command to handle the selected item (e.g. `e`, `tabe`) | | `sink` | funcref | Reference to function to process each selected item | | `sink*` | funcref | Similar to `sink`, but takes the list of output lines at once | | `options` | string | Options to fzf | | `dir` | string | Working directory | | `up`/`down`/`left`/`right` | number/string | Use tmux pane with the given size (e.g. `20`, `50%`) | | `window` (*Neovim only*) | string | Command to open fzf window (e.g. `vertical aboveleft 30new`) | | `launcher` | string | External terminal emulator to start fzf with (Only used in GVim) | _However on Neovim `fzf#run` is asynchronous and does not return values so you should use `sink` or `sink*` to process the output from fzf._ ##### Examples If `sink` option is not given, `fzf#run` will simply return the list. ```vim let items = fzf#run({ 'options': '-m +c', 'dir': '~', 'source': 'ls' }) ``` But if `sink` is given as a string, the command will be executed for each selected item. ```vim " Each selected item will be opened in a new tab let items = fzf#run({ 'sink': 'tabe', 'options': '-m +c', 'dir': '~', 'source': 'ls' }) ``` We can also use a Vim list as the source as follows: ```vim " Choose a color scheme with fzf nnoremap C :call fzf#run({ \ 'source': \ map(split(globpath(&rtp, "colors/*.vim"), "\n"), \ "substitute(fnamemodify(v:val, ':t'), '\\..\\{-}$', '', '')"), \ 'sink': 'colo', \ 'options': '+m', \ 'left': 20, \ 'launcher': 'xterm -geometry 20x30 -e bash -ic %s' \ }) ``` `sink` option can be a function reference. The following example creates a handy mapping that selects an open buffer. ```vim " List of buffers function! s:buflist() redir => ls silent ls redir END return split(ls, '\n') endfunction function! s:bufopen(e) execute 'buffer' matchstr(a:e, '^[ 0-9]*') endfunction nnoremap :call fzf#run({ \ 'source': reverse(buflist()), \ 'sink': function('bufopen'), \ 'options': '+m', \ 'down': len(buflist()) + 2 \ }) ``` More examples can be found on [the wiki page](https://github.com/junegunn/fzf/wiki/Examples-(vim)). #### Articles - [fzf+vim+tmux](http://junegunn.kr/2014/04/fzf+vim+tmux) Tips ---- #### Rendering issues If you have any rendering issues, check the followings: 1. Make sure `$TERM` is correctly set. fzf will use 256-color only if it contains `256` (e.g. `xterm-256color`) 2. If you're on screen or tmux, `$TERM` should be either `screen` or `screen-256color` 3. Some terminal emulators (e.g. mintty) have problem displaying default background color and make some text unable to read. In that case, try `--black` option. And if it solves your problem, I recommend including it in `FZF_DEFAULT_OPTS` for further convenience. 4. If you still have problem, try `--no-256` option or even `--no-color`. #### 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 -l -g "" | fzf # Setting ag as the default source for fzf export FZF_DEFAULT_COMMAND='ag -l -g ""' # Now fzf (w/o pipe) will use ag instead of find fzf ``` #### `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 * -name ".*" -prune -o -type f -print -o -type l -print) 2> /dev/null' ``` #### Using fzf with tmux panes The supplied [fzf-tmux](bin/fzf-tmux) script should suffice in most of the cases, but if you want to be able to update command line like the default `CTRL-T` key binding, you'll have to use `send-keys` command of tmux. The following example will show you how it can be done. ```sh # This is a helper function that splits the current pane to start the given # command ($1) and sends its output back to the original pane with any number of # optional keys (shift; $*). fzf_tmux_helper() { [ -n "$TMUX_PANE" ] || return local cmd=$1 shift tmux split-window -p 40 \ "bash -c \"\$(tmux send-keys -t $TMUX_PANE \"\$(source ~/.fzf.bash; $cmd)\" $*)\"" } # This is the function we are going to run in the split pane. # - "find" to list the directories # - "sed" will escape spaces in the paths. # - "paste" will join the selected paths into a single line fzf_tmux_dir() { fzf_tmux_helper \ 'find * -path "*/\.*" -prune -o -type d -print 2> /dev/null | fzf --multi | sed "s/ /\\\\ /g" | paste -sd" " -' Space } # Bind CTRL-X-CTRL-D to fzf_tmux_dir bind '"\C-x\C-d": "$(fzf_tmux_dir)\e\C-e"' ``` #### Fish shell It's [a known bug of fish](https://github.com/fish-shell/fish-shell/issues/1362) 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 store the result of fzf to a temporary file. ```sh function vimf if fzf > $TMPDIR/fzf.result vim (cat $TMPDIR/fzf.result) end end function fe set tmp $TMPDIR/fzf.result fzf --query="$argv[1]" --select-1 --exit-0 > $tmp if [ (cat $tmp | wc -l) -gt 0 ] vim (cat $tmp) end end ``` #### Handling UTF-8 NFD paths on OSX Use iconv to convert NFD paths to NFC: ```sh find . | iconv -f utf-8-mac -t utf8//ignore | fzf ``` License ------- [MIT](LICENSE) Author ------ Junegunn Choi
