Viewing processes

You can view a table that shows currently running processes and information about them.

There are several tools for this:– Both of these update in real time so you can see what is going on

One is top

man top
top

top

The other is htop, which is the same as top, but has a colour output.

man htop
htop

htop

These are really useful tools, there is also ps

man ps

$ ps
    PID TTY          TIME CMD
  51221 pts/0    00:00:00 bash
  51239 pts/0    00:00:00 ps

ps -a
    PID TTY          TIME CMD
  51251 pts/0    00:00:00 ps

ps -u
USER         PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
psutton    51221  0.0  0.0  11284  5504 pts/0    Ss   22:51   0:00 bash
psutton    51256  0.0  0.0  13760  4608 pts/0    R+   22:53   0:00 ps -u

ps -x

PID TTY      STAT   TIME COMMAND
   2016 ?        Ss     0:00 /usr/lib/systemd/systemd --user
   2017 ?        S      0:00 (sd-pam)
   2029 ?        S<sl   0:13 /usr/bin/pipewire
   2030 ?        Ssl    0:00 /usr/bin/pipewire -c filter-chain.conf
   2031 ?        S<sl   0:00 /usr/bin/wireplumber
   2033 ?        S<sl   0:21 /usr/bin/pipewire-pulse

Note : Above is NOT full output,

If you are ever unsure as to what a process is, you can try seeing if there is a man page.

NAME
       pipewire - The PipeWire media server

If not, you can look it up using a search tool such as duckduckgo, which from this I found info on wireplumber on the Arch Linux wiki.

Ventoy Concerns

I noticed a post on Mastodon, suggesting that due to a number of component blobs that don't have associated source code available, there could be concerns regarding Ventoy

I am just sharing this as concerns were raised, I still feel Ventoy is safe to use. As with anything, due diligence needs to be used when installing any software or OS. If you are concerned, then make the USB media, with the chosen OS and install that way.

Privacy tools list

A discussion on Mastodon on Sunday, resulted in being directed to this excellent list of privacy tools, There is a lot to go through here so if you are looking for alternatives to proprietary solutions this is very worth checking out.

top and htop process viewing and management

Donate using Liberapay

When using a GNU Linux system it is really useful to be able to manage what running process are doing, this could be simply seeing what system resources are being used, or stopping processes from running, to changing how they run with tools such as nice / renice.

The console / terminal top, gives you a view of all the running processes and allows you to control these processes easily.

TOP

top

HTOP

If you would like a slightly different tool that allows you to move up / down the process list, you may want to loop at htop. This seems to offer the same functionality as top. Top is probably better for running so you can keep an eye on what things are doing.

htop

OTHER RELATED TOOLS

These tools offer the sort of functionality that is achieved by commands such as :

  • ps
  • nice
  • renice
  • kill
  • killall

But you need to look these up and read up about them on on the man page(s).
