什么是 viu？

viu is a small but powerful command-line image viewer written in Rust that displays images directly in your terminal. It adapts to your terminal's capabilities, using the best available protocol — from the high-fidelity Kitty and iTerm2 graphics protocols down to Unicode block characters as a universal fallback.

            🚀 Why Latest Versions Matter: viu continuously improves support for new image formats, terminal protocols, and display options. The latest releases include AVIF support, improved Kitty protocol rendering, better GIF animation handling, and performance optimizations for large images.
        

⚡ Key Features of viu

🖼️ Multiple Display Protocols

Supports Kitty terminal graphics protocol, iTerm2 inline images, Sixel graphics, and Unicode block characters — automatically picks the best one for your terminal.

📦 Wide Format Support

Displays PNG, JPEG, GIF, BMP, ICO, TIFF, WebP, AVIF, and many more formats via Rust's image crate.

🎞️ GIF Animation

Plays animated GIFs directly in the terminal, looping through frames at the correct frame rate.

📏 Flexible Sizing

Control width, height, or let viu auto-fit the image to your terminal window. Useful for pipelines and scripting.

🔗 Pipe-Friendly

Reads from stdin or file arguments, making it composable with tools like curl, find, and shell pipelines.

⚡ Fast & Lightweight

Written in Rust — minimal startup time, low memory footprint, and no runtime dependencies beyond the binary.

🖥️ Supported Terminal Protocols

Kitty: Full-resolution pixel-perfect images (kitty, Ghostty, WezTerm)
iTerm2: Inline image protocol (iTerm2, WezTerm, Tabby, VSCode)
Sixel: Compatible with foot, Windows Terminal, and many classic terminals
Unicode blocks: Universal fallback — works in every terminal

📦 Installation from deb.griffo.io

运行命令

步骤 1：添加仓库

sudo install -d -m 0755 /etc/apt/keyrings
curl -fsSL https://deb.griffo.io/EA0F721D231FDD3A0A17B9AC7808B4DD62C41256.asc | sudo gpg --dearmor --yes -o /etc/apt/keyrings/deb.griffo.io.gpg
echo "deb [signed-by=/etc/apt/keyrings/deb.griffo.io.gpg] https://deb.griffo.io/apt $(lsb_release -sc 2>/dev/null) main" | sudo tee /etc/apt/sources.list.d/deb.griffo.io.list > /dev/null
sudo apt update

install -d -m 0755 /etc/apt/keyrings
curl -fsSL https://deb.griffo.io/EA0F721D231FDD3A0A17B9AC7808B4DD62C41256.asc | gpg --dearmor --yes -o /etc/apt/keyrings/deb.griffo.io.gpg
echo "deb [signed-by=/etc/apt/keyrings/deb.griffo.io.gpg] https://deb.griffo.io/apt $(lsb_release -sc 2>/dev/null) main" | tee /etc/apt/sources.list.d/deb.griffo.io.list > /dev/null
apt update

sudo apt install extrepo
sudo extrepo enable griffo
sudo apt update

🆓 有一个永久免费的镜像。 deb-free.griffo.io 永久免费提供软件包 — 无需账号、无需订阅，最多落后上游 2 个月，安全修复立即发布。目前收录 cliamp、Ghostty、lazydocker、Oh My Posh 和 Zed；viu 不在其中，因此今天只能通过上面的仓库安装 — 提出请求即可将其加入。

免费镜像的工作方式 →

🧩 关于 extrepo 选项。 extrepo 是 Debian 官方用于管理第三方仓库的工具：它会替你写好 sources 文件并安装签名密钥，并在使用前先对照签名元数据校验该密钥。本仓库以 griffo 之名登记其中，永久免费镜像则为 griffo-free，因此在 Debian（bookworm、trixie、forky、sid）上，上面的命令就是全部配置。

extrepo 只负责 sources 文件和密钥，订阅凭据仍然要写入 /etc/apt/auth.conf.d/deb.griffo.io.conf。Ubuntu 不在覆盖范围内，因为 extrepo 只发布 Debian 各套件的元数据：在 Ubuntu 上请使用 sudo 或 root 的命令。

步骤 2：安装 viu

# Install latest viu
sudo apt install viu

# Verify installation
viu --version

# Install latest viu
apt install viu

# Verify installation
viu --version

🎯 使用示例

Basic usage:

# Display a single image
viu image.png

# Display multiple images
viu *.jpg

# Display from stdin
curl -sL https://example.com/photo.jpg | viu -

# Display a GIF animation
viu animation.gif

Sizing options:

# Set width in terminal columns
viu -w 80 image.png

# Set height in terminal rows
viu -h 24 image.png

# Disable auto-resizing
viu -s image.png

Pipeline examples:

# Browse images in a directory
for f in ~/Pictures/*.jpg; do viu -w 40 "$f"; done

# Use with fzf to browse and preview
find . -name "*.png" | fzf --preview "viu -w 60 {}"
