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:
$ 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:
$ 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:
$ fzf --preview 'bat --color "always" --line-range 0:100 {}'See man fzf for more details.
