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
Clone this repository and run install script.
git clone https://github.com/junegunn/fzf.git ~/.fzf
~/.fzf/install
The script will setup:
fzf
executable- Key bindings (
CTRL-T
,CTRL-R
, etc.) - Fuzzy auto-completion for bash
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.
-
Edit your .vimrc
call plug#begin() Plug 'junegunn/fzf' " ... call plug#end()
-
Run
:PlugInstall
Usage
usage: fzf [options]
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-insensitive match (default: smart-case match)
+i Case-sensitive match
+c, --no-color Disable colors
--no-mouse Disable mouse
Environment variables
FZF_DEFAULT_COMMAND Default command to use when input is tty
FZF_DEFAULT_OPTS Defaults options. (e.g. "-x -m --sort 10000")
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 $(fzf)
If you want to preserve the exact sequence of the input, provide --no-sort
(or
+s
) option.
history | fzf +s
Key binding
Use CTRL-J and CTRL-K (or CTRL-N and CTRL-P) to change the selection, press enter key to select the item. CTRL-C, CTRL-G, or ESC will terminate the finder.
The following readline key bindings should also work as expected.
- CTRL-A / CTRL-E
- CTRL-B / CTRL-F
- CTRL-W / CTRL-U
- ALT-B / ALT-F
If you enable multi-select mode with -m
option, you can select multiple items
with TAB or Shift-TAB key.
You can also use mouse. Click on an item to select it or shift-click to select multiple items. Use mouse wheel to move the cursor up and down.
Extended-search mode
With -x
or --extended
option, fzf will start in "extended-search mode".
In this mode, you can specify multiple patterns delimited by spaces,
such as: ^music .mp3$ 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 |
Useful 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}
}
Key bindings for command line
The install script will setup the following key bindings.
bash
CTRL-T
- Paste the selected file path(s) into the command lineCTRL-R
- Paste the selected command from history into the command line
The source code can be found in ~/.fzf.bash
.
zsh
CTRL-T
- Paste the selected file path(s) into the command lineCTRL-R
- Paste the selected command from history into the command lineALT-C
- cd into the selected directory
The source code can be found in ~/.fzf.zsh
.
Auto-completion
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 and ~/.ssh/config.
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
TODO 😃
(Pull requests are appreciated.)
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.
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.
Ranking algorithm
fzf sorts the result first by the length of the matched substring, then by the length of the whole string. However it only does so when the number of matches is less than the limit which is by default 1000, in order to avoid the cost of sorting a large list and limit the response time of the query.
This limit can be adjusted with -s
option, or with the environment variable
FZF_DEFAULT_OPTS
.
export FZF_DEFAULT_OPTS="--sort 20000"
