Prock - Process Explorer for Linux

Prock is a fast, graphical alternative to htop/btop, inspired by the Sysinternals Process Explorer. It shows a process tree, live system charts, per-process charts, and detailed inspectors for libraries, sockets, threads, and environment — with controls to suspend, kill, or reprioritize processes.

How to try it?

There are two ways to try it:

• Clone the repo and run the install script (provides a desktop entry and easy updates, so a bit more convenient).
• Download the single binary from the releases page.

Features

Process Monitoring

• Filter by name, PID; Use '+' to filter to a subtree
• Sort by any column
• Choose the order and which columns to display
• Copy process info or entire table
• Kill SIGTERM, force kill SIGKILL, or kill entire process tree
• Tree view or a sortable list showing parent-child relationships
• Set CPU affinity and nice priority
• Suspend SIGSTOP / resume SIGCONT processes
• Create a core dump (via gcore) without terminating the process

System Charts

• CPU usage (total, kernel, interrupts)
• Toggle to show per-core and stacked charts (per-core toggles the format for all views globally)
• Memory usage (used vs available)
• Disk I/O throughput (read/write MB/s)
• Network throughput (send/receive MB/s)

Per-Process Details

• Right-click any process to open:
  • Charts (CPU, memory, I/O)
  • Properties
  • Loaded libraries with mapped/file sizes
  • Memory maps with address, permissions, RSS/PSS/swap, and grouping by mapping
  • Sockets
  • Threads
  • Open files (fd, type, access, size, path)
  • Environment variables
• Double-click to open all windows at once

Listening Ports

• System-wide view of listening ports
• Kill the owning process directly from the table

Charts & Navigation

• Toggle "Auto-Follow" on all charts and tables (Space)
• Toggle continuous Y-axis auto-fit (Shift+Space)
• Per-core and stacked CPU chart views
• Zoom the UI in / out (Ctrl++ / Ctrl+-)
• Command palette for all actions (Ctrl+P)
• Vim-style navigation (Ctrl+J/K/H/L as Down/Up/Left/Right)
• Context menu for the selected table row (Ctrl+Enter)
• Menu bar, optionally shown only on Alt

Appearance & Preferences

• Themes: Dark, Light, Classic, Enemymouse, Nord, OneNord, Everforest Dark, Everforest Light
• Custom TTF font
• Adjustable window opacity, UI scale, target FPS, and update interval

Runtime Dependencies

The released prock binary targets glibc 2.17+, so it runs on most Linux distros. It dynamically loads the libraries below, which are already present on a standard desktop install:

• glibc 2.17+ — libc, libm, libpthread, libdl
• OpenGL ES 2.0 + EGL — libGLESv2.so.2, libEGL.so.1
• FreeType — libfreetype.so.6
• A display backend, one of:
  • X11 — libX11.so.6 libXcursor, libXi, libXrandr, libXinerama
  • Wayland — libwayland-client.so.0, libwayland-cursor.so.0, libwayland-egl.so.1, libxkbcommon.so.0

Optionally, the "Create Dump File" action shells out to gcore (shipped with gdb); install gdb to enable it.

On a minimal or headless system, install them explicitly:

Debian/Ubuntu:

sudo apt install libgles2 libegl1 libfreetype6 libx11-6 libxcursor1 libxi6 libxrandr2 libxinerama1 libwayland-client0 libwayland-cursor0 libwayland-egl1 libxkbcommon0

Arch Linux:

sudo pacman -S mesa libglvnd freetype2 libx11 libxcursor libxi libxrandr libxinerama wayland libxkbcommon
