#1 Post by metman »

Need info on what it is as I have never seen it before. I have Debian 11 with Xfce.

I also had never heard of a task called Ruler, so I did a search. This was the only thing I found. I don't know if that is what you have, but it sounds rather unfriendly.

Can't imagine that you would have that program unless you actually downloaded and installed it. I searched through the Debian Stable package list and there is no package by that name. So I'm stumped.

These should tell you what started it:

By name:

Code: Select all

$ ps -A -f | grep ruler
By ID number:

Code: Select all

$ ps -fp <ID>
Or just search for rhe package:

Code: Select all

# dpkg -l | grep ruler

@ticojohn It does sound ominous but it seems not to be something installed in my system.
@FreewheelinFrank It terminated after only a couple of seconds, so I can't list it. Dpkg search gives nothing.
Thank you for your help guys, anything else?

Spooky! :twisted:
Does it show up randomly or maybe only when you first start the system? Since you are using XFCE you can look at the menu Settings >> Sessions and Startup and maybe determine what might be launching Ruler. Look at the Application Autostart and the Current Session tabs. Maybe you can find a clue there.

Code: Select all

$ top -b -c > top.txt
(Records output to text file.)

Modified from:

https://askubuntu.com/questions/726333/ ... ut-to-file

Make the terminal full screen because output is truncated to terminal width.

Without specifying the number of iterations this goes on forever, so kill it once you have seen the mysterious "ruler"

Good idea from @FreewheelinFrank. I just thought of something that might be faster. Try this. Don't need to be root. Process names are case sensitive.

Code: Select all

pidof Ruler
Assuming it is still running it should show the pid.

To be honest I saw it just once and for very short time. No, process is not active any more. I searched entire disk and am pretty sure I don't have any package called Ruler (or ruler) nor any file that contains that word in its name installed. But I think a process name doesn't have to be same as file name. So... mystery goes on...
