#267831 — Useful Unix compatible commands

[Multipart message — attachments visible in raw view] — view raw

Sorry for the misleading post the other day. However, I have been reading a Unix system administrators textbook. 

ps -e

This lists the processes

In that display (if I'm correct) if you see a program that has extremely high time, then you should kill the process.

kill process

There is also

ls -R

This command lists the files in each subdirectory.

If you know any more that can work on GNU compatible software or Unix compatible software please indicate the commands in your reply.

_Definitely_ not blindly.

For example, among the highest-time processes on my system I currently
see xfce4-panel, Xorg, apcupsd, rclone and a few ZFS housekeeping
processes. Among slightly lower times, there's xfwm4, pipewire and
systemd-journal. (All of these share the trait that they also have
been running for a long period of wallclock time.) Another that could
show up would likely be qemu/KVM related processes for long-running
VMs, but I don't have any up and running currently. And if I'm doing
something like watching a movie, mpv or one of its friends would
probably be right up there as well.

Killing those would have potentially severe negative impacts on my
ability to actually use the computer to perform normal, useful tasks.

_That a process is doing a lot of work doesn't by itself mean that it
shouldn't be running._

Perhaps you want to read the Debian Administrator's Handbook? 

https://www.debian.org/doc/manuals/debian-handbook/

Or an introduction to Linux command line work?

Or to BASH?

Your question is very unfocused.

This is a decent introduction to the important commands:
