etop

A full-screen terminal dashboard for CPU, memory, disk, network, processes and containers — built on libsysmon's collectors, drawn with Ink.

Install (optional)

npx @aibulat/etop needs no install. If you reach for it often enough to want a shorter command:

npm install -g @aibulat/etop
etop

Node 22 or newer. If you only want numbers to script against, install libsysmon instead — it runs on Node 18, has one runtime dependency, and cpumon --json pipes into jq.

Keys

? inside the dashboard shows them all. The essentials:

| Key | | | --- | --- | | q | quit | | Tab | move between screens | | w 1–6 | move between panels, on the dashboard | | Space | freeze the view (sampling continues) | | / | filter processes by name or pid | | c m p n s | sort the process table | | + - | change the sampling interval | | K | send a signal — needs --allow-kill |

Options

npx @aibulat/etop [options]

  -i, --interval <ms>  sampling interval in milliseconds  (default: 1000)
      --mount <path>   filesystem the disk panel reports on
      --theme <name>   auto, default, ansi16 or mono
      --graph <style>  auto, block, braille or ascii
      --allow-kill     enable sending signals to processes from the table
      --no-color       draw without colour

Notes

Screens, then panels. Tab walks whole screens — the dashboard, a full-height process table, containers, compose stacks, systemd units, tcp and udp connections, and wifi. Inside the dashboard, w and 1–6 move between the tiles.

It adapts to the terminal rather than assuming one. Truecolor, 256-colour, 16-colour and monochrome all get a theme that stays legible; a non-UTF-8 locale or the Linux console gets ASCII graphs and borders with nothing outside ASCII in the frame. Panels are dropped whole rather than squeezed as the window shrinks, down to a single-panel mode that w walks; the tab bar sheds tabs from the end rather than the one you are on.

It is honest about what it cannot read. Network, per-process figures and containers need /proc, so on macOS and Windows those panels are removed and the rest reflow, with one line saying why. A read that failed for a reason you could act on keeps its panel and reports the reason instead.

Signals are off by default. --allow-kill turns them on; the confirmation names the process, pins it when the modal opens, freezes the list underneath, defaults to SIGTERM, and confirms on y rather than Enter.
