I really wish you wrote a free PDF book with all this explanation for beginner to intermediate level. Believe me I read several books about Linux. Nothing gets even closer to your clarity, simplicity, and in-deep explanation you give to your subscribers. I am really loyal followers of you and I glad your channel crossed my Linux Journey a long time ago! Sir you are great!

Hi! You are the only youtuber that have my likes even before watch the contents!. Many thanks for your videos. Keep on.

[MrEric]

Thank you so much for that. Now I have a better understanding of the ps command I never did before. One thing you left me wanting though was to sort by CPU and Mem so I looked it up.
ps aux --sort pcpu
or
ps aux --sort pmem

sort by percent CPU or sort by percent memory.

Again thank you for making the linux experience more enjoyable.

Awesome Jay, ps makes a prerequisite to top, I guess

[Heck-edsr]

Hey Jay, noticed @7:31 you mentioned a capital S means the process is in uninterruptible sleep. Did you mean interruptible sleep instead? The man page tells me 'S' is for interruptible sleep and 'D' is for uninterruptible sleep.

One of the first commands I learned are ps ax | grep *processname* and then I could tap kill -9 PID

[Heck-edsr]

Can someone help to explain why I get the same result when running 'ps aux' and 'ps -aux'? Doesn't the options mean different things when written in Linux and BSD style?

[vamankumar]

Hi Jay...I have one question from my side. When the tty shows as "?" ...what would that tell us. Is the process not running at that time?

[MrMackster]

When I first saw ‘TTY’ in Linux, I thought it was short for TTYL ‘talk to you later ‘ 😂🤨

[Raphael-qlpf]

What's the difference ps and ps fx? Processes Inside outside terminal

[Mikesco]

I would have just mentioned stop on the outro just as a bonus

[swinnburn]

I wish I could do this with my brain!?

[darren]

What do you you guys learn Linux for? Is there a point if your not a programmer or IT networking Tech

[thomasblackwell]

Sorry to bother you, but I noticed that you changed the font size while you were using it. What is the command that you are using to do that? Thank you.

[Jkauppa]

does not give gpu usage, nor does system monitor, or top

Why is BSD style still so popular?
Because it saves you hitting one dash key?
There are only few Unix commands where you can avoid the dash.
E.g. tar, like in
gzip -dc tarball.tgz | (cd /path/to/untar/target && tar xvf -)
This used to be the way to untar to different directory on Unices before the advent of GNU tar with its -C option.
Another dashless options command that comes to mind is the convert and copy command dd.
Although I'm old enough to have known BSD style I never could get used to it and quickly adopted POSIX style with the single dashes and later on GNU style with the double dashes for long opts.
