+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`.
