Usage examples can be found in the Examples section below.
+#### Get notified on file hover
+
+If `NNN_FIFO` is set, `nnn` will open it and write every hovered files. This can be used in plugins, e.g. to implement file previews.
+
+If a `NNN_FIFO` is set globally, each `nnn` instance will write to it, and a process reading from the pipe will get hovered path from every instance, interleaved.
+
+If you want to prevent this and be sure to have a private pipe to one `nnn` instance, you can unlink (remove) the FIFO file. If you had opened the FIFO before and you have read from it (so that `nnn` have it opened too), you can still read from it while you don't close it. But new `nnn` instances will recreate a new FIFO not linked to the previous one.
+
+Don't forget to fork in the background to avoid blocking `nnn`.

#### Examples
There are many plugins provided by `nnn` which can be used as examples. Here are a few simple selected examples.
printf "%s" "0c$dir" > "$NNN_PIPE"
```

-Example (send every hovered file to X selection):
-
-```sh
-#!/usr/bin/env sh
-if [ -z "$NNN_FIFO" ] ; then
- exit 1
-fi
-
-while read FILE ; do
- if [ -n "$NNN_FIFO" ] ; then
- # If you want to remove the FIFO,
- # don't do it before first read,
- # nnn won't have it opened yet
- rm "$NNN_FIFO"
- NNN_FIFO=
- fi
- printf "%s" "$FILE" | xsel
-done < "$NNN_FIFO" &
-disown
-```
