# Show A File Preview When Searching With FZF
|
|
|
|
[FZF](https://github.com/junegunn/fzf) by itself is a great way to fuzzy
|
|
find files. It gets even better when you can view a preview of a file before
|
|
opening it up. The `--preview` flag lets you do just this.
|
|
|
|
Add a basic file preview with `cat`:
|
|
|
|
```bash
|
|
$ fzf --preview 'cat {}'
|
|
```
|
|
|
|
The `{}` will get replaced a single-quoted string of the highlighted file.
|
|
|
|
You can spice up the preview a bit with color and line numbers using
|
|
[`bat`](https://github.com/sharkdp/bat):
|
|
|
|
```bash
|
|
$ fzf --preview 'bat --color "always" {}'
|
|
```
|
|
|
|
The `--color` flag tells `bat` to produce syntax highlighted output even
|
|
though it isn't in interactive mode.
|
|
|
|
Lastly, you can keep it performant by only showing the first 100 lines:
|
|
|
|
```bash
|
|
$ fzf --preview 'bat --color "always" --line-range 0:100 {}'
|
|
```
|
|
|
|
See `man fzf` for more details.
