fust

A minimal system fetch tool written in Rust. Shows your system info next to your distro's ascii art. That's it.

What it shows

• Hostname and kernel version
• OS name, uptime, shell
• CPU model
• GPU(s) via pci-ids
• RAM usage and swap
• Disk usage for /
• How long it took to run and how much memory it used

Supported distros

Arch, Alpine, Asahi, CachyOS, EndeavourOS, Ubuntu, Debian, Fedora, NixOS — anything else falls back to a generic Linux logo.

Building

You need Rust installed. Then:

git clone https://github.com/temidaradev/fust
cd fust
cargo build --release

Binary ends up at target/release/fust. Move it wherever you want it.

sudo cp target/release/fust /usr/local/bin/

Running

fust

No flags, no config file. It reads everything straight from /proc and /etc.

Dependencies

• libc — for the statvfs disk stat call
• pci-ids — bundled PCI ID database for GPU detection (no external tools needed)

How GPU detection works

Reads /sys/class/drm/*/device/uevent, parses PCI_ID=VENDOR:DEVICE, looks up vendor and device name via the pci-ids crate. No lspci or pciutils required.
