Linux Candy: pscircle visualizes Linux processes in a form of radial tree

In Operation

pscircle is a CLI program so you’ll need to see the available options (and there are lots of them). The options are displayed with $ pscircle --help

By default, pscircles outputs to the X11 root window.

Many desktop environments such as GNOME and KDE don’t display the root window. As we’re running GNOME, we need to save the image to a file using --output=file.png.

The list below explains some of the options available:

  • By default pscircle calculates CPU utilization and processes PCPU values from system start time and process start time. But using --interval=1 the values are calculated over a specified interval.
  • Run pscircle in the background as a daemon with the option of a loop delay.
  • Define the output height and width.
  • Set the maximum number of child processes.
  • Color options for processes with RSS/CPU etc above and below a defined value.
  • Various tree options such as setting the position of a tree center, set the difference between radii of concentric circles, define tree rotation angle and more.
  • Define colors for different elements such as the background color of the dots.
  • Option to display processes owned by root.

Here’s an example with lots of different options set.

$ pscircle --background-color=1e2226 --link-color-min=375143a0 --link-color-max=375143 --dot-color-min=7c762f --dot-color-max=b56e46 --tree-font-size=18 --tree-font-color=94bfd1 --tree-font-face="Noto Sans" --toplists-row-height=35 --toplists-font-size=24 --toplists-font-color=C8D2D7 --toplists-pid-font-color=7B9098 --toplists-font-face="Liberation Sans" --toplists-bar-height=7 --toplists-bar-background=444444 --toplists-bar-color=7d54dd --output=pscircle-example.png

The image generated from that command is shown below.

Summary

We wouldn’t describe pscircle as an essential utility. But it offers a different take on the venerable ps command.

Given that most users use a desktop environment like KDE or GNOME that don’t display the X11 root window as desktop wallpaper, the usefulness of pscircle is rather niche. If you’re running such a desktop environment you’ll be limited to saving the image to a file, and then set the path to the image in your wallpaper system config. More enterprising users could craft a script to update the wallpaper automatically.
