Anchor htop to one specific process?

rated 0 times [ 37] [ 0] / answers: 1 / hits: 21828 / 1 Year ago, wed, march 22, 2023, 10:04:50

I have a long list of processes displayed in htop, but I am only interested in one of them. As old processes terminate and new processes are spawned, htop keeps updating the displayed list of processes, which means that the one process I am interested in keeps jumping up and down the list.

Is it possible to disable this behavior somehow?

That is, I would like to anchor the scroll to this particular process. How can I do this?

You can't anchor a given process line to the top but htop can follow a process if you press Shift+F. From the man page:

   F    "Follow" process: if the sort order causes the currently  selected

        process  to  move  in  the list, make the selection bar follow it.

        This is useful for monitoring a process: this way, you can keep  a

        process  always  visible  on  screen. When a movement key is used,

        "follow" loses effect.

Here I'm following my Firefox process:

Note that if you're only interested in one particular process, the -p <pid> will do what you want (12352 is the pid of Firefox on my system):

$ htop -p 12352
