nnn — n³ The Fastest Terminal File Manager Ever Written

What it is

nnn (n-cubed) is a full-featured, ultra-fast terminal file manager written in C. It starts instantly, uses minimal memory, and provides features like type-to-navigate, a plugin ecosystem, disk usage analysis, batch renaming, and filesystem mounting.

nnn targets power users, sysadmins, and developers who spend significant time navigating filesystems in the terminal. It replaces both basic ls/cd workflows and heavier file managers like ranger or mc with a lighter, faster alternative.

The project is actively maintained and suitable for both individual developers and teams looking to integrate it into their existing toolchain. Documentation and community support are available for onboarding.

How it saves time or tokens

nnn launches in under 10 milliseconds and handles directories with thousands of files without lag. Type-to-navigate lets you jump to files by typing the first few characters instead of scrolling. Batch rename operations that would require multi-line shell scripts happen in a single keystroke. Plugins extend functionality without bloating the core binary.

How to use

1. Install via your package manager (brew install nnn, apt install nnn, or build from source).
2. Launch with nnn in any directory. Navigate with arrow keys or vim-style hjkl.
3. Type characters to filter files by name (type-to-nav). Press Enter to open or descend into directories.
4. Use ; to invoke plugins for operations like preview, archive extraction, or batch rename.

Example

# Install nnn with plugin support
brew install nnn

# Launch with hidden files shown and detail mode
nnn -dH

# Set up plugins (one-time)
curl -Ls https://raw.githubusercontent.com/jarun/nnn/master/plugins/getplugs | sh

# Use environment variables for customization
export NNN_PLUG='p:preview-tui;f:fzfcd;d:diffs'
export NNN_FCOLORS='0000E6310000000000000000'

Common pitfalls

• Not installing plugins. Vanilla nnn is deliberately minimal. Most users want the preview, fzf integration, and archive plugins for a complete experience.
• Expecting GUI-like file previews without a terminal image protocol. Preview plugins work best in terminals that support sixel or kitty image protocol.
• Ignoring the NNN_PLUG environment variable. This is how you bind plugins to hotkeys. Without it, you have to type plugin names manually each time.
• Not reading the changelog before upgrading. Breaking changes between versions can cause unexpected failures in production. Pin your version and review release notes.
