----
|
||||
|
||||
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! **
|
||||
# *********************
|
||||
export FZF_DEFAULT_OPTS='--preview "bat --style=numbers --color=always {} | head -500"'
|
||||
|
||||
# bat doesn't work with any input other than the list of files

#### `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 ||
|
||||

sed s/^..//) 2> /dev/null'

#### Fish shell
|
||||
|
||||
Fish shell before version 2.6.0 [doesn't allow](https://github.com/fish-shell/fish-shell/issues/1362)
|
||||
reading from STDIN in command substitution, which means simple `vim (fzf)`
|
||||
doesn't work as expected. The workaround for fish 2.5.0 and earlier is to use
|
||||
the `read` fish command:
|
||||
|
||||
```sh
|
||||
fzf | read -l result; and vim $result
|
||||
```
|
||||
|
||||
or, for multiple results:
|
||||
|
||||
```sh
|
||||
fzf -m | while read -l r; set result $result $r; end; and vim $result
|
||||
```
|
||||
|
||||
The globbing system is different in fish and thus `**` completion will not work.
|
||||
However, the `CTRL-T` command will use the last token on the command-line as the
|
||||
root folder for the recursive search. For instance, hitting `CTRL-T` at the end
|
||||
of the following command-line
|
||||
`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
|
||||
|
||||
```sh

ls /var/

```
