It's extremely light and fast (**[performance](https://github.com/jarun/nnn/wiki/Performance)**). `nnn` is also a disk usage analyzer, a fuzzy app launcher, a batch file renamer and a file picker. 30+ **[plugins](https://github.com/jarun/nnn/tree/master/plugins)** extend the capabilities further. There's an independent [(neo)vim plugin](https://github.com/mcchrish/nnn.vim). Custom plugins are easy to add. It runs smoothly on the Raspberry Pi, Termux on Android ([demo video](https://www.youtube.com/watch?v=AbaauM7gUJw)), Linux, macOS, BSD, Cygwin and Linux subsystem for Windows. `nnn` works seamlessly with DEs and GUI utilities. It's nearly zero-config (with sensible defaults) and can be setup in less than 5 minutes. Visit the **[Wiki](https://github.com/jarun/nnn/wiki)** for operational concepts, how tos, use cases, chronology and insights. ## Features - Modes - Detail (default), light - Disk usage analyzer (block/apparent) - File picker, (neo)vim plugin - Navigation - *Navigate-as-you-type* with dir auto-select - 4 contexts (_aka_ tabs/workspaces) - Bookmarks; pin and visit a directory - Familiar, easy shortcuts (arrows, ~, -, @) - Change directory at exit (*easy* shell integration) - Sorting - Ordered pure numeric names by default (visit _/proc_) - Case-insensitive version (_aka_ natural) sort - By file name, modification/access time, size, extension - Search - Instant filtering with *search-as-you-type* - Regex and substring match - Subtree search to open or edit files (using plugin) - Mimes - Open with desktop opener or specify a custom app - Create, list, extract archives - Option to open all text files in EDITOR - Information - Detailed file information - Media information (using plugin) - Convenience - Minimal configuration - Plugin keybinds - Select files across dirs; all/range selection - Copy, move, delete, archive, link selection - Batch rename selection or dir entries - FreeDesktop compliant trash (needs trash-cli) - SSHFS mounts (needs sshfs) - Create, rename, duplicate files and directories - Per-context directory color (default: blue) - Spawn a shell, run apps, run commands, execute file - Take quick notes, lock terminal (needs a locker) - Shortcut reference a keypress away - Unicode support - Follows Linux kernel coding style - Highly optimized, static analysis integrated code - Minimal library dependencies - Widely available ## Installation #### Library dependencies `nnn` needs a curses library with wide character support (like ncursesw), libreadline and standard libc. It's possible to drop libreadline using the Makefile target `norl`. #### Utility dependencies | Dependency | Installation | Operation | | --- | --- | --- | | xdg-open (Linux), open(1) (macOS), cygstart (Cygwin) | base | desktop opener | | file, coreutils (cp, mv, rm), findutils (xargs) | base | file type, copy, move and remove | | tar, (un)zip [atool/bsdtar for more formats] | base | create, list, extract tar, gzip, bzip2, zip | | sshfs, fusermount(3) | if needed | mount, unmount over SSHFS | | trash-cli | optional | trash files (default action: delete) | | vlock (Linux), bashlock (macOS), lock(1) (BSD) | optional | terminal locker (fallback: [cmatrix](https://github.com/abishekvashok/cmatrix)) | | advcpmv (Linux) ([integration](https://github.com/jarun/nnn/wiki/Advanced-use-cases#show-cp-mv-progress)) | optional | copy, move progress | | `$VISUAL` (else `$EDITOR`), `$PAGER`, `$SHELL` | optional | fallback vi, less, sh | #### From a package manager `nnn` may be available in the default repos of your distro already.
