fzf - Fuzzy finder for your shell

fzf is a general-purpose fuzzy finder for your shell.

It was heavily inspired by ctrlp.vim and the likes.

Requirements

fzf requires Ruby (>= 1.8.5).

Installation

Using install script

Clone this repository and run install script.

git clone https://github.com/junegunn/fzf.git ~/.fzf
~/.fzf/install

The script will generate ~/.fzf.bash and ~/.fzf.zsh and update your .bashrc and .zshrc to load them.

Manual installation

Or you can just download fzf executable and put it somewhere in your search $PATH.

mkdir -p ~/bin
wget https://raw.github.com/junegunn/fzf/master/fzf -O ~/bin/fzf
chmod +x ~/bin/fzf

Install as Ruby gem

fzf can be installed as a Ruby gem

gem install fzf

It's a bit easier to install and update the script but the Ruby gem version takes slightly longer to start.

Install as Vim plugin

You can use any Vim plugin manager to install fzf for Vim. If you don't use one, I recommend you try vim-plug.

1. Install vim-plug

2. Edit your .vimrc

    call plug#begin()
    Plug 'junegunn/fzf'
    " ...
    call plug#end()
   

3. Run :PlugInstall

Usage

usage: fzf [options]

    -m, --multi      Enable multi-select
    -x, --extended   Extended-search mode
    -q, --query=STR  Initial query
    -s, --sort=MAX   Maximum number of matched items to sort. Default: 1000
    +s, --no-sort    Do not sort the result. Keep the sequence unchanged.
    +i               Case-sensitive match
    +c, --no-color   Disable colors

fzf will launch curses-based finder, read the list from STDIN, and write the selected item to STDOUT.

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)

vim $(fzf)

If you want to preserve the exact sequence of the input, provide --no-sort (or +s) option.

history | fzf +s

Key binding

Use CTRL-J and CTRL-K (or CTRL-N and CTRL-P) to change the selection, press enter key to select the item. CTRL-C, CTRL-G, or ESC will terminate the finder.

The following readline key bindings should also work as expected.

• CTRL-A / CTRL-E
• CTRL-B / CTRL-F
• CTRL-W / CTRL-U
• ALT-B / ALT-F

If you enable multi-select mode with -m option, you can select multiple items with TAB or Shift-TAB key.

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

Usage as Vim plugin

If you install fzf as a Vim plugin, :FZF command will be added.

" Look for files under current directory
:FZF

" Look for files under your home directory
:FZF ~

" With options
:FZF --no-sort -m /tmp

You can override the source command which produces input to fzf.

let g:fzf_source = 'find . -type f'

And you can predefine default options to fzf command.

let g:fzf_options = '--no-color --extended'

For more advanced uses, you can call fzf#run function as follows.

:call fzf#run('tabedit', '-m +c')

Most of the time, you will prefer native Vim plugins with better integration with Vim. The only reason one might consider using fzf in Vim is its speed. For a very large list of files, fzf is significantly faster and it does not block.

Useful bash examples

# vimf - Open selected file in Vim
vimf() {
  FILE=$(fzf) && vim "$FILE"
}

# fd - cd to selected directory
fd() {
  DIR=$(find ${1:-*} -path '*/\.*' -prune -o -type d -print 2> /dev/null | fzf) && cd "$DIR"
}

# fda - including hidden directories
fda() {
  DIR=$(find ${1:-*} -type d 2> /dev/null | fzf) && cd "$DIR"
}

# fh - repeat history
fh() {
  eval $(history | fzf +s | sed 's/ *[0-9]* *//')
}

# fkill - kill process
fkill() {
  ps -ef | sed 1d | fzf -m | awk '{print $2}' | xargs kill -${1:-9}
}

bash key bindings

# Required to refresh the prompt after fzf
bind '"\er": redraw-current-line'

# CTRL-T - Paste the selected file path into the command line
fsel() {
  find ${1:-*} | fzf -m | while read item; do
    printf '%q ' "$item"
  done
  echo
}
bind '"\C-t": " \C-u \C-a\C-k$(fsel)\e\C-e\C-y\C-a\C-y\ey\C-h\C-e\er"'

# CTRL-R - Paste the selected command from history into the command line
bind '"\C-r": " \C-e\C-u$(history | fzf +s | sed \"s/ *[0-9]* *//\")\e\C-e\er"'

zsh widgets

# CTRL-T - Paste the selected file path(s) into the command line
fzf-file-widget() {
  local FILES
  local IFS="
"
  FILES=($(
    find * -path '*/\.*' -prune \
    -o -type f -print \
    -o -type l -print 2> /dev/null | fzf -m))
  unset IFS
  FILES=$FILES:q
  LBUFFER="${LBUFFER%% #} $FILES"
  zle redisplay
}
zle     -N   fzf-file-widget
bindkey '^T' fzf-file-widget

# ALT-C - cd into the selected directory
fzf-cd-widget() {
  cd "${$(find * -path '*/\.*' -prune \
          -o -type d -print 2> /dev/null | fzf):-.}"
  zle reset-prompt
}
zle     -N    fzf-cd-widget
bindkey '\ec' fzf-cd-widget

# CTRL-R - Paste the selected command from history into the command line
fzf-history-widget() {
  LBUFFER=$(history | fzf +s | sed "s/ *[0-9]* *//")
  zle redisplay
}
zle     -N   fzf-history-widget
bindkey '^R' fzf-history-widget

Auto-completion (experimental)

Disclaimer: Auto-completion feature is currently experimental, it can change over time

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]**<TAB>

# Files under 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. In this case there is no trigger sequence, just press tab key after 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 host names is provided. The names are extracted from /etc/hosts file.

ssh <TAB>
telnet <TAB>

Settings

# Use ~~ as the trigger sequence instead of the default **
export FZF_COMPLETION_TRIGGER='~~'

# Options to fzf command
export FZF_COMPLETION_OPTS='+c -x'

zsh

Tips

Faster startup with --disable-gems options

If you're running Ruby 1.9 or above, you can improve the startup time with --disable-gems option to Ruby.

• time ruby ~/bin/fzf -h
  • 0.077 sec
• time ruby --disable-gems ~/bin/fzf -h
  • 0.025 sec

You can define fzf function with the option as follows:

fzf() {
  ruby --disable-gems ~/bin/fzf "$@"
}
export -f fzf

However, this is automatically set up in your .bashrc and .zshrc if you use the bundled install script.

Incorrect display on Ruby 1.8

It is reported that the output of fzf can become unreadable on some terminals when it's running on Ruby 1.8. If you experience the problem, upgrade your Ruby to 1.9 or above. Ruby 1.9 or above is also required for displaying Unicode characters.
