`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.

Upgrading fzf
|
|
|
|
-------------
|
|
|
|
|
2021-01-12 19:26:10 +00:00
|
|
|
fzf is being actively developed, and you might want to upgrade it once in a
|
2017-01-31 12:43:41 +00:00
|
|
|
while. Please follow the instruction below depending on the installation
|
|
|
|
method used.
|
|
|
|
|
|
|
|
- git: `cd ~/.fzf && git pull && ./install`
|
2021-01-07 07:50:08 +00:00
|
|
|
- brew: `brew update; brew upgrade fzf`
|
2020-02-26 08:58:54 +00:00
|
|
|
- macports: `sudo port upgrade fzf`
|
2017-03-29 16:59:41 +00:00
|
|
|

Building fzf
|
|
|
|
------------
|
|
|
|
|
|
|
|

Usage
|
|
|
|
-----
|
|
|
|
|
2017-04-05 17:08:49 +00:00
|
|
|
fzf will launch interactive finder, read the list from STDIN, and write the
|
2013-10-23 01:26:55 +00:00
|
|
|
selected item to STDOUT.
|
|
|
|
|
|
|
|
```sh
|
|
|
|
find * -type f | fzf > selected
|
|
|
|
```
|
|
|
|
|
|
|
|
Without STDIN pipe, fzf will use find command to fetch the list of
|
2013-11-02 03:56:43 +00:00
|
|
|
files excluding hidden ones. (You can override the default command with
|
|
|
|
`FZF_DEFAULT_COMMAND`)
|
2013-10-23 01:26:55 +00:00
|
|
|
|
|
|
|
```sh
|
2013-11-06 11:54:02 +00:00
|
|
|
vim $(fzf)
|
2013-10-23 01:26:55 +00:00
|
|
|
```
|
|
|

### Using the finder
|
2013-11-09 18:56:18 +00:00
|
|
|
|
2021-08-15 06:57:07 +00:00
|
|
|
- `CTRL-K` / `CTRL-J` (or `CTRL-P` / `CTRL-N`) to move cursor up and down
|
2015-03-06 09:57:36 +00:00
|
|
|
- `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
|
2014-03-06 11:52:38 +00:00
|
|
|
|
2023-01-22 17:23:25 +00:00
|
|
|
### Layout
|
2017-01-07 16:30:31 +00:00
|
|
|
|
|
|
|
fzf by default starts in fullscreen mode, but you can make it start below the
|
|
|
|
cursor with `--height` option.
|
|
|
|
|
|
|
|
```sh
|
|
|
|
vim $(fzf --height 40%)
|
|
|
|
```
|
|
|
|
|
2021-01-12 19:26:10 +00:00
|
|
|
Also, check out `--reverse` and `--layout` options if you prefer
|
2018-06-09 16:41:50 +00:00
|
|
|
"top-down" layout instead of the default "bottom-up" layout.
|
2017-01-07 16:30:31 +00:00
|
|
|
|
|
|
|
```sh
|
|
|
|
vim $(fzf --height 40% --reverse)
|
|
|
|
```
|
|
|
|
|
|
|
|
You can add these options to `$FZF_DEFAULT_OPTS` so that they're applied by
|
2017-02-04 12:51:22 +00:00
|
|
|
default. For example,
|
2017-01-07 16:30:31 +00:00
|
|
|
|
|
|
|
```sh
|
2018-06-09 16:41:50 +00:00
|
|
|
export FZF_DEFAULT_OPTS='--height 40% --layout=reverse --border'
|
2017-01-07 16:30:31 +00:00
|
|
|
```
|
|
|
|
|
2023-01-22 17:23:25 +00:00
|
|
|
### Search syntax
|
2015-11-03 18:16:36 +00:00
|
|
|
|
|
|
|
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
|
2016-10-03 17:17:36 +00:00
|
|
|
!fire`
|
|
|
|
|
2018-03-06 07:33:33 +00:00
|
|
|
| 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` |
|
2013-11-15 11:40:57 +00:00
|
|
|
|
2015-09-12 04:31:07 +00:00
|
|
|
If you don't prefer fuzzy matching and do not wish to "quote" every word,
|
2015-11-03 13:49:32 +00:00
|
|
|
start fzf with `-e` or `--exact` option. Note that when `--exact` is set,
|
|
|
|
`'`-prefix "unquotes" the term.
|
2014-03-04 12:29:45 +00:00
|
|
|
|
2015-11-08 15:58:20 +00:00
|
|
|
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$
|
|
|
|
```
|
|
|
|
|

`fzf-tmux` script
|
|
|
|
-----------------
|
|
|
|
|
|
|
|
[fzf-tmux](bin/fzf-tmux) is a bash script that opens fzf in a tmux pane.
|
|
|
|
|
|
|
|
```sh
|
2020-03-31 13:18:09 +00:00
|
|
|
# usage: fzf-tmux [LAYOUT OPTIONS] [--] [FZF OPTIONS]
|
|
|
|
|
|
|
|
# See available options
|
|
|
|
fzf-tmux --help
|
2016-05-02 15:07:53 +00:00
|
|
|
|
|
|
|
# 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
|
|
|
|
```
|
|
|
|
|
2020-03-31 13:18:09 +00:00
|
|
|
It will still work even when you're not on tmux, silently ignoring `-[pudlr]`
|
2016-05-02 15:07:53 +00:00
|
|
|
options, so you can invariably use `fzf-tmux` in your scripts.
|
|
|
|
|
2017-01-07 16:30:31 +00:00
|
|
|
Alternatively, you can use `--height HEIGHT[%]` option not to start fzf in
|
|
|
|
fullscreen mode.
|
|
|
|
|
|
|
|
```sh
|
|
|
|
fzf --height 40%
|
|
|
|
```
|

|
|
|

If you're on a tmux session, you can start fzf in a tmux split-pane or in
|
2023-01-19 04:25:08 +00:00
|
|
|
a tmux popup window by setting `FZF_TMUX_OPTS` (e.g. `export FZF_TMUX_OPTS='-p80%,60%'`).
|

2021-01-12 19:26:10 +00:00
|
|
|
the cursor ends with the trigger sequence, which is by default `**`.

### Supported commands
|
2015-11-12 04:47:52 +00:00
|
|
|
|
|
|
|
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
|
2019-12-06 03:03:34 +00:00
|
|
|
commands as well by using `_fzf_setup_completion` helper function.
|
2015-11-12 04:47:52 +00:00
|
|
|
|
|
|
|
```sh
|
2019-12-20 09:39:22 +00:00
|
|
|
# usage: _fzf_setup_completion path|dir|var|alias|host COMMANDS...
|
2019-12-06 03:03:34 +00:00
|
|
|
_fzf_setup_completion path ag git kubectl
|
|
|
|
_fzf_setup_completion dir tree
|
2015-11-12 04:47:52 +00:00
|
|
|
```
|
|
|
|
|
2023-01-22 17:23:25 +00:00
|
|
|
### Custom fuzzy completion
|
2020-03-11 09:29:39 +00:00
|
|
|
|
|
|
|
_**(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 **<TAB>
|
|
|
|
_fzf_complete_doge() {
|
|
|
|
_fzf_complete --multi --reverse --prompt="doge> " -- "$@" < <(
|
|
|
|
echo very
|
|
|
|
echo wow
|
|
|
|
echo such
|
|
|
|
echo doge
|
|
|
|
)
|
|
|
|
}
|
|
|
|
```
|
|
|
|
|
|
|
|
- The arguments before `--` are the options to fzf.
|
|
|
|
- After `--`, simply pass the original completion arguments unchanged (`"$@"`).
|
2021-01-12 19:26:10 +00:00
|
|
|
- Then, write a set of commands that generates the completion candidates and
|
2020-03-11 09:29:39 +00:00
|
|
|
feed its output to the function using process substitution (`< <(...)`).
|
|
|
|
|
|
|
|
zsh will automatically pick up the function using the naming convention but in
|
2021-01-12 19:26:10 +00:00
|
|
|
bash you have to manually associate the function with the command using the
|
2020-03-11 09:29:39 +00:00
|
|
|
`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
|
|
|
|
```

Advanced topics

|
|
|
|
|
### Performance
|
|
|
|
|
2023-01-13 12:10:18 +00:00
|
|
|
fzf is fast. Performance should not be a problem in most use cases. However,
|
|
|
|
you might want to be aware of the options that can affect performance.
|
2017-07-29 08:08:51 +00:00
|
|
|
|
2021-01-12 19:26:10 +00:00
|
|
|
- `--ansi` tells fzf to extract and parse ANSI color codes in the input, and it
|
2017-07-29 08:08:51 +00:00
|
|
|
makes the initial scanning slower. So it's not recommended that you add it
|
|
|
|
to your `$FZF_DEFAULT_OPTS`.
|
2021-01-12 19:26:10 +00:00
|
|
|
- `--nth` makes fzf slower because it has to tokenize each line.
|
2017-07-29 08:08:51 +00:00
|
|
|
- `--with-nth` makes fzf slower as fzf has to tokenize and reassemble each
|
|
|
|
line.
|
|
|
|
|
|
|
|
### Executing external programs
|
|
|
|
|
2017-07-29 08:12:46 +00:00
|
|
|
You can set up key bindings for starting external processes without leaving
|
|
|
|
fzf (`execute`, `execute-silent`).
|
2017-07-29 08:08:51 +00:00
|
|
|
|
2017-07-29 08:12:46 +00:00
|
|
|
```bash
|
|
|
|
# Press F1 to open the file with less without leaving fzf
|
2017-07-29 08:08:51 +00:00
|
|
|
# Press CTRL-Y to copy the line to clipboard and aborts fzf (requires pbcopy)
|
|
|
|
fzf --bind 'f1:execute(less -f {}),ctrl-y:execute-silent(echo {} | pbcopy)+abort'
|
|
|
|
```
|
|
|
|
|
|
|
|
See *KEY BINDINGS* section of the man page for details.
|
|
|
|
|
2023-02-12 15:57:51 +00:00
|
|
|
### Turning into a different process
|
|
|
|
|
|
|
|
`become(...)` is similar to `execute(...)`/`execute-silent(...)` described
|
|
|
|
above, but instead of executing the command and coming back to fzf on
|
|
|
|
complete, it turns fzf into a new process for the command.
|
|
|
|
|
|
|
|
```sh
|
|
|
|
fzf --bind 'enter:become(vim {})'
|
|
|
|
```
|
|
|
|
|
|
|
|
Compared to the seemingly equivalent command substitution `vim "$(fzf)"`, this
|
|
|
|
approach has several advantages:
|
|
|
|
|
|
|
|
* Vim will not open an empty file when you terminate fzf with
|
|
|
|
<kbd>CTRL-C</kbd>
|
|
|
|
* Vim will not open an empty file when you press <kbd>ENTER</kbd> on an empty
|
|
|
|
result
|
|
|
|
* Can handle multiple selections even when they have whitespaces
|
|
|
|
```sh
|
|
|
|
fzf --multi --bind 'enter:become(vim {+})'
|
|
|
|
```
|
|
|
|
|
|
|
|
To be fair, running `fzf --print0 | xargs -0 -o vim` instead of `vim "$(fzf)"`
|
|
|
|
resolves all of the issues mentioned. Nonetheless, `become(...)` still offers
|
|
|
|
additional benefits in different scenarios.
|
|
|
|
|
|
|
|
* You can set up multiple bindings to handle the result in different ways
|
|
|
|
without any wrapping script
|
|
|
|
```sh
|
|
|
|
fzf --bind 'enter:become(vim {}),ctrl-e:become(emacs {})'
|
|
|
|
```
|
|
|
|
* Previously, you would have to use `--expect=ctrl-e` and check the first
|
|
|
|
line of the output of fzf
|
|
|
|
* You can easily build the subsequent command using the field index
|
|
|
|
expressions of fzf
|
|
|
|
```sh
|
|
|
|
# Open the file in Vim and go to the line
|
|
|
|
git grep --line-number . |
|
|
|
|
fzf --delimiter : --nth 3.. --bind 'enter:become(vim {1} +{2})'
|
|
|
|
```
|
|
|

|

|
### 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
|
2023-05-25 14:54:55 +00:00
|
|
|
ps -ef |
|
|
|
|
fzf --bind 'ctrl-r:reload(ps -ef)' \
|
2020-10-05 10:16:40 +00:00
|
|
|
--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' \
|
2022-07-29 13:02:10 +00:00
|
|
|
fzf --bind 'ctrl-d:reload(find . -type d),ctrl-f:reload(eval "$FZF_DEFAULT_COMMAND")' \
|
2020-10-05 10:16:40 +00:00
|
|
|
--height=50% --layout=reverse
|
|
|
|
```
|
|
|
|
|
|
|
|
#### 3. Interactive ripgrep integration
|
|
|
|
|
|
|
|
The following example uses fzf as the selector interface for ripgrep. We bound
|
2021-01-12 19:26:10 +00:00
|
|
|
`reload` action to `change` event, so every time you type on fzf, the ripgrep
|
2020-10-05 10:16:40 +00:00
|
|
|
process will restart with the updated query string denoted by the placeholder
|
2021-08-14 11:33:22 +00:00
|
|
|
expression `{q}`. Also, note that we used `--disabled` option so that fzf
|
2021-03-25 11:36:01 +00:00
|
|
|
doesn't perform any secondary filtering.
|
2020-10-05 10:16:40 +00:00
|
|
|
|
|
|
|
```sh
|
2023-05-25 14:54:55 +00:00
|
|
|
: | rg_prefix='rg --column --line-number --no-heading --color=always --smart-case' \
|
|
|
|
fzf --bind 'start:reload:$rg_prefix ""' \
|
|
|
|
--bind 'change:reload:$rg_prefix {q} || true' \
|
|
|
|
--bind 'enter:become(vim {1} +{2})' \
|
|
|
|
--ansi --disabled \
|
|
|
|
--height=50% --layout=reverse
|
2020-10-05 10:16:40 +00:00
|
|
|
```
|
|
|
|
|
|
|
|
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
|
|
|
|
|
2020-10-18 08:03:33 +00:00
|
|
|
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`.
|
2020-06-04 02:57:01 +00:00
|
|
|
The window can be scrolled using the mouse or custom key bindings.
|
2017-07-29 08:08:51 +00:00
|
|
|
|
2017-07-29 08:12:46 +00:00
|
|
|
```bash
|
2021-01-12 19:26:10 +00:00
|
|
|
# {} is replaced with the single-quoted string of the focused line
|
2017-07-29 08:08:51 +00:00
|
|
|
fzf --preview 'cat {}'
|
|
|
|
```
|
|
|
|
|
2019-12-13 03:43:34 +00:00
|
|
|
Preview window supports ANSI colors, so you can use any program that
|
2020-10-18 08:03:33 +00:00
|
|
|
syntax-highlights the content of a file, such as
|
2020-06-04 02:57:01 +00:00
|
|
|
[Bat](https://github.com/sharkdp/bat) or
|
|
|
|
[Highlight](http://www.andre-simon.de/doku/highlight/en/highlight.php):
|
2017-07-29 08:08:51 +00:00
|
|
|
|
2017-07-29 08:12:46 +00:00
|
|
|
```bash
|
2023-01-13 12:10:18 +00:00
|
|
|
fzf --preview 'bat --color=always {}' --preview-window '~3'
|
2017-07-29 08:08:51 +00:00
|
|
|
```
|
|
|
|
|
2019-12-13 03:43:34 +00:00
|
|
|
You can customize the size, position, and border of the preview window using
|
2019-12-17 16:07:25 +00:00
|
|
|
`--preview-window` option, and the foreground and background color of it with
|
|
|
|
`--color` option. For example,
|
2017-07-29 08:08:51 +00:00
|
|
|
|
2017-07-29 08:12:46 +00:00
|
|
|
```bash
|
2019-12-17 16:07:25 +00:00
|
|
|
fzf --height 40% --layout reverse --info inline --border \
|
2021-04-06 13:53:59 +00:00
|
|
|
--preview 'file {}' --preview-window up,1,border-horizontal \
|
2023-01-13 12:10:18 +00:00
|
|
|
--bind 'ctrl-/:change-preview-window(50%|hidden|)' \
|
2019-12-17 16:07:25 +00:00
|
|
|
--color 'fg:#bbccdd,fg+:#ddeeff,bg:#334455,preview-bg:#223344,border:#778899'
|
2017-07-29 08:08:51 +00:00
|
|
|
```
|
|
|
|
|
2019-12-13 03:43:34 +00:00
|
|
|
See the man page (`man fzf`) for the full list of options.

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! **
|
|
|
|
# *********************
|
2020-06-04 02:57:01 +00:00
|
|
|
export FZF_DEFAULT_OPTS='--preview "bat --style=numbers --color=always --line-range :500 {}"'
|
2019-12-13 03:43:34 +00:00
|
|
|
|
|
|
|
# bat doesn't work with any input other than the list of files
|
|
|
|
ps -ef | fzf
|
|
|
|
seq 100 | fzf
|
|
|
|
history | fzf
|

### Previewing an image
|
|
|
|
|
2024-01-17 04:21:00 +00:00
|
|
|
fzf can display images in the preview window using one of the following protocols:
|
|
|
|
|
|
|
|
* [Kitty graphics protocol](https://sw.kovidgoyal.net/kitty/graphics-protocol/)
|
|
|
|
* [iTerm2 inline images protocol](https://iterm2.com/documentation-images.html)
|
|
|
|
* [Sixel](https://en.wikipedia.org/wiki/Sixel)
|
|
|
|
|
|
|
|
See [bin/fzf-preview.sh](bin/fzf-preview.sh) script for more information.

### Respecting `.gitignore`
|
2014-04-06 06:25:58 +00:00
|
|
|
|
2017-10-29 14:34:26 +00:00
|
|
|
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`.
|
2014-04-06 06:25:58 +00:00
|
|
|
|
|
|
|
```sh
|
2017-10-29 14:34:26 +00:00
|
|
|
# Feed the output of fd into fzf
|
2022-08-08 04:38:21 +00:00
|
|
|
fd --type f --strip-cwd-prefix | fzf
|
2014-04-06 06:25:58 +00:00
|
|
|
|
2017-10-29 14:34:26 +00:00
|
|
|
# Setting fd as the default source for fzf
|
2022-08-08 04:38:21 +00:00
|
|
|
export FZF_DEFAULT_COMMAND='fd --type f --strip-cwd-prefix'
|
2014-04-06 06:25:58 +00:00
|
|
|
|
2017-10-29 14:34:26 +00:00
|
|
|
# Now fzf (w/o pipe) will use fd instead of find
|
2014-04-06 06:25:58 +00:00
|
|
|
fzf
|
2015-06-30 04:17:48 +00:00
|
|
|
|
|
|
|
# To apply the command to CTRL-T as well
|
|
|
|
export FZF_CTRL_T_COMMAND="$FZF_DEFAULT_COMMAND"
|
2014-04-06 06:25:58 +00:00
|
|
|
```
|
|
|
|
|
2021-01-12 19:26:10 +00:00
|
|
|
If you want the command to follow symbolic links and don't want it to exclude
|
2017-10-29 14:34:26 +00:00
|
|
|
hidden files, use the following command:
|
2016-09-12 19:11:28 +00:00
|
|
|
|
|
|
|
```sh
|
2022-08-08 04:38:21 +00:00
|
|
|
export FZF_DEFAULT_COMMAND='fd --type f --strip-cwd-prefix --hidden --follow --exclude .git'
|
2016-09-12 19:11:28 +00:00
|
|
|
```
|
|
|
|
|
2023-03-20 04:00:33 +00:00

|
### Fish shell
|
2014-05-02 02:27:32 +00:00
|
|
|
|
2019-12-13 03:43:34 +00:00
|
|
|
`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
|
2016-12-14 06:37:27 +00:00
|
|
|
|
|
|
|
```sh
|
|
|
|
ls /var/
|
|
|
|
```
|
|
|
|
|
2019-12-13 03:43:34 +00:00
|
|
|
will list all files and directories under `/var/`.
|
2016-12-14 06:37:27 +00:00
|
|
|
|
|
|
|
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
|
2017-06-22 16:50:45 +00:00
|
|
|
set -g FZF_CTRL_T_COMMAND "command find -L \$dir -type f 2> /dev/null | sed '1d; s#^\./##'"
|
2014-05-02 02:27:32 +00:00
|
|
|
```
|
|
|
|
|
