nnn

nnn is a terminal file manager for working with files and directories. It supports copying, moving, deleting, archiving, and linking selections, along with batch renaming, disk-usage analysis, app launching, and file picking. Navigation options include contexts, sessions, bookmarks, and directory marks; searches can use instant filtering, fuzzy matching, regular expressions, or string filters. Directory and text previews are built in, and plugins can add live previews, disk mounting, file comparison, or uploads. nnn can create, list, extract, and mount archives. Remote mounts require optional sshfs or rclone integrations. The project describes nnn as privacy-aware, with no unconfirmed user data collection. It has no configuration file, uses defaults, and permits optional environment-variable settings. It is free and open source under the BSD-2-Clause license. The project says it typically uses less than 3.5 MB of resident memory. It is available for Android, Linux, macOS, and Windows; the listed platform facts indicate no Windows support. Installation options include packages, a statically linked binary, and compiling from source.

nnn combines file operations, previews, search, and plugin options in a terminal file manager. Remote mounting depends on optional integrations, and some features require external utilities.

nnn suits users who want a terminal-based file manager with multiple navigation and search options. Its documented quickstarts address both beginners and power users.

nnn is a free, open-source terminal file manager for people who want file operations, search, and previews in a compact tool. It is best for users comfortable working in a terminal; the lack of a dual-pane view and reliance on optional utilities narrow its fit for other workflows.

Overview

nnn combines everyday file handling with disk-usage analysis, batch renaming, app launching, and file picking. It can copy, move, delete, archive, and link selections, so it serves as more than a directory navigator. The project says it typically uses less than 3.5 MB of resident memory, a useful trait on resource-constrained systems.

It starts without a configuration file, relying on sensible defaults, while environment variables allow optional customization. That keeps setup light for users content with the defaults, but offers less of a visual workspace than a conventional graphical manager. The project describes its privacy approach as avoiding unconfirmed user-data collection.

Key features

Navigation and search

Contexts, sessions, bookmarks, and directory marks give users several ways to organize movement between locations. Search-as-you-type, fuzzy search, string filters, and regex search help narrow file lists without relying on a single search style. These tools add flexibility for terminal workflows, but the interface itself is not a fit for users who prefer graphical file browsing.

Previews, archives, and plugins

Directory and text previews, plus preview plugins, help inspect files without leaving the manager. nnn can create, list, extract, and mount archives, extending its usefulness for users who handle compressed files regularly. Language-agnostic plugins can add live previews, file comparison, uploads, and disk mounting; that flexibility comes with more setup and dependency management than a self-contained graphical app.

Remote access and integrations

Remote mounts work through sshfs or rclone, both optional dependencies, so remote access is possible but not built into the core installation. Desktop openers, shell integration, and FreeDesktop-compliant trash utilities broaden the workflows it can join. Some features also depend on external utilities, so users seeking a uniform, ready-to-go setup may prefer another manager.

Pricing

There is no paid tier or free trial. The BSD-2-Clause license makes nnn free to use, while installation options include packages, a statically linked binary, and compiling from source. Its wide-character curses library and libc are required; libreadline is optional.

Platforms

nnn supports Android, Linux, and macOS. Windows is not supported. Installation is offered through packages or a static binary, with source compilation as another option.

Who it's for

nnn is a strong match for terminal users who want navigation, search, file operations, archives, and previews without starting from a configuration file. Its low stated memory use and plugin options also suit users who value a compact tool they can extend. It is less suitable for people who need a dual-pane layout, want a graphical-first manager, or expect remote mounting and other integrations to work without optional utilities.

Pros and cons

Pros

• Broad file operations, including batch renaming, disk-usage analysis, and archive handling, reduce the need to switch tools for routine work.
• Contexts, sessions, bookmarks, and multiple search modes support varied navigation habits.
• Directory and text previews, plugins, and optional remote mounts extend the core workflow.
• Free and open source, with a stated typical resident-memory footprint below 3.5 MB.

Cons

• No dual-pane layout, which limits side-by-side file management.
• Remote mounts require optional sshfs or rclone, and some other features need external utilities.
• The terminal interface excludes users who want a conventional graphical manager.
• GitHub reports no SECURITY.md file and no published security advisories, so users seeking published project security guidance may want another option.
