fzf - Fuzzy finder for your shell
|
|
=================================
|
|
|
|
fzf is a general-purpose fuzzy finder for your shell.
|
|
|
|
|
|
|
|
It was heavily inspired by [ctrlp.vim](https://github.com/kien/ctrlp.vim) and
|
|
the likes.
|
|
|
|
Requirements
|
|
------------
|
|
|
|
fzf requires Ruby (>= 1.8.5).
|
|
|
|
Installation
|
|
------------
|
|
|
|
Download fzf executable and put it somewhere in your search $PATH.
|
|
|
|
```sh
|
|
mkdir -p ~/bin
|
|
wget https://raw.github.com/junegunn/fzf/master/fzf -O ~/bin/fzf
|
|
chmod +x ~/bin/fzf
|
|
```
|
|
|
|
Or you can just clone this repository and run
|
|
[install](https://github.com/junegunn/fzf/blob/master/install) script.
|
|
|
|
```sh
|
|
git clone https://github.com/junegunn/fzf.git
|
|
fzf/install
|
|
```
|
|
|
|
Make sure that ~/bin is included in $PATH.
|
|
|
|
```sh
|
|
export PATH=$PATH:~/bin
|
|
```
|
|
|
|
### 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](https://github.com/junegunn/vim-plug).
|
|
|
|
1. [Install vim-plug](https://github.com/junegunn/vim-plug#usage)
|
|
2. Edit your .vimrc
|
|
|
|
call plug#begin()
|
|
Plug 'junegunn/fzf'
|
|
" ...
|
|
call plug#end()
|
|
|
|
3. Run `:PlugInstall`
|
|
|
|
Usage
|
|
-----
|
|
|
|
```
|
|
usage: fzf [options]
|
|
|
|
-s, --sort=MAX Maximum number of matched items to sort. Default: 500
|
|
+s, --no-sort Keep the sequence unchanged.
|
|
+i Case-sensitive match
|
|
```
|
|
|
|
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`
|
|
```
|
|
|
|
If you want to preserve the exact sequence of the input, provide `--no-sort` (or
|
|
`+s`) option.
|
|
|
|
```sh
|
|
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 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
|
|
|
|
Usage as Vim plugin
|
|
-------------------
|
|
|
|
If you install fzf as a Vim plugin, `:FZF` command will be added.
|
|
|
|
```vim
|
|
:FZF
|
|
:FZF --no-sort
|
|
```
|
|
|
|
You can override the command which produces input to fzf.
|
|
|
|
```vim
|
|
let g:fzf_command = 'find . -type f'
|
|
```
|
|
|
|
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
|
|
--------------------
|
|
|
|
```sh
|
|
# 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 | awk '{print $2}' | xargs kill -${1:-9}
|
|
}
|
|
|
|
# (Assuming you don't use the default CTRL-T and CTRL-R)
|
|
|
|
# CTRL-T - Paste the selected file path into the command line
|
|
bind '"\er": redraw-current-line'
|
|
bind '"\C-t": " \C-u \C-a\C-k$(fzf)\e\C-e\C-y\C-a\C-y\ey\C-h\C-e\er"'
|
|
|
|
# CTRL-R - Paste the selected command from history into the command line
|
|
bind '"\C-r": " \C-e\C-u$(history | fzf +s | sed \"s/ *[0-9]* *//\")\e\C-e\er"'
|
|
