How to Install and Use a TUI File Manager

A TUI file manager brings visual, navigable file browsing directly into the terminal — genuinely faster for many keyboard-oriented workflows than switching to a separate graphical file manager application.

Step 1: choose a TUI file manager

ranger   — vim-inspired keybindings, built-in file previews
nnn      — extremely lightweight and fast, plugin-extensible
lf       — minimal, highly scriptable, written in Go

Each has a genuinely different philosophy — ranger prioritizes rich previews and vim-like navigation, nnn prioritizes raw speed and minimal resource usage, lf prioritizes scriptability and configuration simplicity.

Step 2: install your chosen file manager

# ranger
sudo apt install ranger      # Debian/Ubuntu
brew install ranger          # macOS

# nnn
sudo apt install nnn
brew install nnn

Step 3: launch it and learn the core navigation keys

j/k   move down/up
h/l   go up a directory / enter a directory
q     quit

Most TUI file managers default to vim-style keybindings for navigation — consistent with the broader terminal tooling ecosystem’s general preference for keyboard-first, modal interaction.

Step 4: preview files without opening them in a separate application

ranger: automatically shows text file contents, image
  previews (with the right terminal and dependencies),
  and archive contents in a side pane

Built-in previews are one of the biggest practical advantages over a plain ls-based workflow — you can visually confirm a file’s contents before deciding to open, move, or delete it.

Step 5: perform standard file operations

ranger:
  dd    cut
  yy    copy
  pp    paste
  dD    delete
  cw    rename

These operate exactly like their vim editing-equivalent mnemonics (d for cut/delete, y for yank/copy, p for paste), a deliberate design choice making the keybindings easier to remember for anyone already familiar with vim.

Step 6: use bulk rename for renaming multiple files at once

ranger: select multiple files (Space), then press "bulkrename"
  — opens your $EDITOR with a list of filenames to edit as text,
  applying the renames when you save and close

Editing filenames as plain text in your normal editor, rather than renaming one file at a time through dialogs, is a genuinely efficient way to handle batch renames.

Step 7: navigate directly to a specific directory quickly

ranger: type a partial path, or use bookmarks (m to set,
  ' to jump to a bookmark)
nnn: type '/ then a search term for a built-in fuzzy jump

Step 8: integrate with the actual shell you’re using

# ranger can change your shell's actual working directory
# on exit via a shell function wrapper — check the specific
# tool's documentation for your shell

By default, a TUI file manager’s navigation only affects its own internal state — configuring shell integration so that quitting the file manager leaves your actual shell in the directory you navigated to is a commonly desired, well-documented setup step worth doing.

Why a TUI file manager is worth learning alongside plain shell commands

cd, ls, and mv remain the right tools for scripted, repeatable file operations — a TUI file manager’s real advantage is interactive, exploratory browsing: previewing unfamiliar files, visually confirming a directory’s contents before acting on them, and performing bulk operations more efficiently than issuing individual shell commands one at a time.
