tuxctl

tuxctl is a lightweight, keyboard-first control-center TUI for Linux, written in Rust with Ratatui and Crossterm. One terminal window shows the system at a glance, the processes, systemd services, the journal and the network interfaces, and it stays cheap while it runs: about 0.6 % of one core and under 3 MiB of memory when idle (static build; loading NVML for an NVIDIA GPU adds about 20 MiB).

What it does

• Overview: cards for CPU, GPU, memory, network, storage and pinned processes, with graphs, temperatures and power, colored by load.
• Processes: a sortable, searchable process list with pinning and safe SIGTERM / SIGKILL, confirmed before anything is sent.
• Services: systemd units and their states, filtered and searchable.
• Logs: the systemd journal, followed live, filtered by priority.
• Network: interfaces with live rates, addresses and counters.

Every screen works with the keyboard; the mouse can switch tabs, select rows, sort, scroll and press buttons.

Principles

• Restrained: a readable interface rather than as much as possible on screen.
• Cheap while idle: data is collected in the background at a chosen interval, and the screen is redrawn only when something visible changed.
• Safe: text from other users can never reach the terminal as escape sequences, and signals go only to the exact process that was confirmed.
• Linux-native: it reads /proc, /sys, systemctl and journalctl directly and asks for no privileges.

Start with Installation, then the Controls.
