Same here since 1999... Only used kill with -1, -2, -9... fg and bg were new to me. But as a lazy dev I've used it from' top' (even better 'htop') or directly with 'xkill' - point and click style :).

I don't think I ever hear such clear explanations. Thank you very much! Instead of using 'clear', you could use 'CTRL+L'.
This was an excellent video that got me up to speed in a hurry. Very well organized and nicely explained. A great jumping off point for my own exploration. Thank you!
11:54 We can use `watch -n 2 jobs` to monitor jobs command every 2 seconds. so we can show the realtime result from pane 1 when the process killed at pane 2. some energy efficiency and fun than manually type a repetitive command.
I am learning this at college, but everyone one is struggling due to our harsh teacher making the most hardest test questions. He does not give good material to study, but thank God I came across your channel. I finally understand the real purposes of these commands and enjoy this now!
I wish knew your name to properly address my thanks to you and this great video...The quality f your explanation but also the goodwill to share it with the community, my deep respect!!!
this was so incredibly well explained. my prof was making a shit show out of this chapter by just throwing a bunch of words at us. going back and reading his lecture notes, i can understand it now, and i furthur can see how poorly written his lecture was. thank so much for this.
The few videos of yours I've seen are excellent and simple explanations! I will be sharing these with my friends (who are learning) and also my users from my Raspberry Pi series. cheers!
I wonder what distro are you using since your 'kill -l' output is so different than mine. Yours is more complete and is numbered while mine is just a list of signals, completely useless. As usual great video, very well prepared and organized, and your communication skills are superb ;) you are a very good teacher. I've been a linux user since 1998 and still learning things. Very much appreciated.
Most shells supply a "builtin" version of kill, try: "type kill". The presenter uses the Bash shell. I use Z-Shell, and its builtin is quite terse. try "/bin/kill -L".
Thank You man! I really like your videos. I know what those commands do, but Your explanation of what is really happening in Linux is golden! Yo have a gift to explain things and teach people. Great, great stuff. It's helping me a lot.
UNBELIEVABLE !!!...why??? Personally I have the habit to check the ratio dislike/like of all videos I intend to watch. I don't go around looking for higher or lower ratios, I just do it before watching it. That said, most of excelent videos I have watched has a ratio score between 1% and 3%. This video of yours has the impressively amazing ratio of 0.35% (5/1400)... You got a new susbscriber and a big fan on a 20 years linux admin.
Ctrl c sends a SIGINT signal. Init is the first process pid = 1 Bash first fork (copies ) the process and than exec (replaces ) the process as child process. T = stopped state S = Interuptable sleep state ( Running in bg) Kill -15 Kill -2 Kill -1 Kill -9 ( my fav )
One thing I find very useful is having a process run outside of their parent process So For example if i run a long running process on the bash terminal I can exit the terminal and check on the process later on. You can do this with the screen command.
3:05 Perhaps make it clearer by pointing out that the “exec” command is a bash builtin which tells it to skip the fork() call before running the rest of the line as the actual command.
hey just started watching your videos and they have helped me a lot. i like they way you explain. Would you be willing to do a video explaining named pipes for server-client, using multithreading or select() for parallel requests? Thank your for your videos, and keep up the great work :)
Processes are very powerful if you understand them. Theres this wonderful site called man7 that covers processes, daemons, and much much more. Theres also lots of IBM documentation on how to write a processe. Anyway thanks for the vid I haven't studied it in a while.
thanks for the wonderful explanation , can you tell us how the kill-3 command is used for taking thread dumps .. i mean i know that this command takes the java thread dump but wanted to know the working as i see kill -3 is sigquit...
Thank you! - Do you, by any chance, happen to know what the "ps f" equvalent on a Mac terminal is? (Google tells me I need to install "pstree", but that doesn't do it...)
Any idea why on some new envs when I run cntrl c it kills my shell. Example, I’m in Oracle, hit control c to kill a running job or command and I end up in my user account, out of Oracle. Nobody I know has a solution. I thought it was a server setting, but sa can’t figure it out. Instead of control c control z works somewhat but I’ve got years of using control c, it’s reflexive habit and super annoying. Using putty.
Been a linux user since 1995 but I still learned something. Thank you!
Glad I could bring you some new knowledge!
Same (1993) Still have trusty Using Linux Sixth Edition (QUE) on my desk..
Same here since 1999... Only used kill with -1, -2, -9... fg and bg were new to me. But as a lazy dev I've used it from' top' (even better 'htop') or directly with 'xkill' - point and click style :).
I don't think I ever hear such clear explanations. Thank you very much!
Instead of using 'clear', you could use 'CTRL+L'.
But it's not the same as clear. It just scrolls the current prompt to the top, you can still see the older commands when scrolling back up
and when you go ‘set -o vi’ to enable vi mode at the bash prompt ‘ctrl-L’ does not work
these linux videos are fantastic
I'm 3 minutes in & I've learned A LOT!
Thank you! You're the kind of people we need on youtube regarding linux.
This was an excellent video that got me up to speed in a hurry.

Thanks for this awesome tip! This is a game-changer!

That was amazing Engineer; wish i could 'fg' all of my postponed tasks and "kill -20 bad-mood" !
Why not kill -9 it :D
U mean 9?
Always appreciate the quality of your videos. Goes in depth, but accessible to beginners
That's my aim :)
I wish knew your name to properly address my thanks to you and this great video...The quality f your explanation but also the goodwill to share it with the community, my deep respect!!!
My name is Brian :)

Glad it helped :)
Where was this 3 months ago during my Operating Systems course?
You're looking for W. Richard Stevens' books on UNIX programming, where all of this stuff is explained in detail.
going through it right now in OS course and it is kicking my ass
I feel like I am watching the Rockwell Retro Encabulator video
Just a wow content .. awesome man that u indirectly mentioned about difference between killed and terminated process ..love u
your content is neat and tidy I can't be grateful more for what you've done on this channel. your contribution for linux learning community is huge
Great content! I've recently started working with linux again and it's awesome to get to know more!
I want to thank you for the quality of your videos, not just this one. All of your videos
You're welcome!
I'm happy that I recognized all the commands :)
Very well explained. Keep uploading such videos. Sound clarity is really good.
These are very involved processes, but you explain it all so well, and in such a good order. Thanks!!
The few videos of yours I've seen are excellent and simple explanations! I will be sharing these with my friends (who are learning) and also my users from my Raspberry Pi series. cheers!
Thank you :)
Thank YOU :)
really love these videos, I'm learning a lot. Very very accessible and clear videos, please keep up the good work.
Dude props on how well you explain everything!
Very helpful. I've only ever seen htop for process management and this helps to understand the underlying signals being sent. Thanks!
Great job! Recently found these series and am fascinated! Subscribed immediately! Keep up the good work!
You make the concept of these command so clear. Thank you soooo much

:) Welcome.
Thanks you for this video . Would like to see more on Linux/unix series
Good job 👍🏻 The way you explain is awesome. Even knowing such things I continued watching. Keep it up!
Thanks for the kind words, hope I helped in some way.
Been using unux since 1980 and linux sice 1995. This is good stuff!
Wow :O
Great as usual!
Thank you. This really helps me for my current project
Ctrl c sends a SIGINT signal.
Init is the first process pid = 1
Bash first fork (copies ) the process and than exec (replaces ) the process as child process.
T = stopped state
S = Interuptable sleep state ( Running in bg)
Kill -15
Kill -2
Kill -1
Kill -9 ( my fav )
3:36 specifying ps options without a dash is BSD-style syntax. Probably best avoided.
You are a life saver. You are exactly what I need right now. TY.
after watching 15 sec I knew that this is proper and what I was actually looking for :D
Brilliant and simple explanation about kill signals. Thank you.
One thing I find very useful is having a process run outside of their parent process So For example if i run a long running process on the bash terminal I can exit the terminal and check on the process later on. You can do this with the screen command.
I appreciate you sharing wisdom to linux noobs like myself
3:05 Perhaps make it clearer by pointing out that the “exec” command is a bash builtin which tells it to skip the fork() call before running the rest of the line as the actual command.
Thanks man! You just upgraded my workflow.
Really nice and clear. Would you like to make an video about using strace ?
You have taught me that kernel has parent ID of zero.
This is the foundational level upon which I shall build many great things.
It's a kernel like a popcorn kernel.
Diprotic there is a grain of truth in that.
Great video, Informative, thanks for sharing🙏
Thanks so much for these videos. You’re truly a jack of all tech trades.
They took yerr jobs !!! Great video man btw. I learned some things from this which my Operating Systems teacher didn't teach me. :)
It's funny that kill can also bring a process to life as well.
Excellent explanation of the above terms
hey just started watching your videos and they have helped me a lot. i like they way you explain. Would you be willing to do a video explaining named pipes for server-client, using multithreading or select() for parallel requests? Thank your for your videos, and keep up the great work :)
Also check out pstree, which lets you view processes as a tree, helps you see the forks and execs.
Learned too much with this video, thanks too much man!
Thank you for teaching us Linux, Programmer Mrbeast
That was amazingly clear and insightful.
Superb clarity as usual!
Great video ... Learned a lot ... You're a gentleman and a scholar ...
I'm really enjoying these videos. Thanks
Thanks for the videos. Keep them coming!
9:53 Not any more. It shows the notification that the process has terminated, and when you do another “jobs” listing, it won’t appear any more.
really love your videos I learned a lot of stuff about killing
Clear and concise information. Thank you!
Processes are very powerful if you understand them. Theres this wonderful site called man7 that covers processes, daemons, and much much more. Theres also lots of IBM documentation on how to write a processe. Anyway thanks for the vid I haven't studied it in a while.
I learn a lot from your videos. Thanks!
Thanks dude, pretty clear and simple!
Very interesting, hopefully I can use these in shell scripts for something
Exactly what I needed. THANKS!
FYI It is possible for "kill -9" to fail.
If it does, the disk is probably full.
Or it's waiting for an io operation. It happened to me on a networked drive
Great linux videos. I hope more are coming cuz i rly want to learn linux
8:48 And the fifth one matches the command doing the searching itself. Why? Because searching for that word brings up the search for the word, too.
Super helpful, super concise, thanks!
I just like getting the uptime of my pi-hole and Jellyfin server Pi. Two weeks so far, hoping no power blackouts!
I love that mr. beast takes up software engineering.
Hehe
Great video.
Why do different jobs listings appear for different bash log-in sessions?
thanks Mr.Beast for this very good explanation 😁😅
Hi Engineer Man,
Have a series of videos on sed and awk commands..
Thanks in advance..
An Engineer
I have learned something new. Thanks much.
Awesome! Where can I find more information like this? I wish to learn and have deep understanding of Linux functioning, commands, etc
Better then my teacher :) awesome man
thanks for the wonderful explanation , can you tell us how the kill-3 command is used for taking thread dumps .. i mean i know that this command takes the java thread dump but wanted to know the working as i see kill -3 is sigquit...
Nice video for recap as a linux user
I would never expect young Che Guevara to make such good clean videos. Thanks.
Lmao.
Thank you! - Do you, by any chance, happen to know what the "ps f" equvalent on a Mac terminal is? (Google tells me I need to install "pstree", but that doesn't do it...)
great video, you just earned another subscriber
Very good explenation ! - subscribed :)
Awesome vedio.....All linux users should have a look
Are you planning to talk about process groups and sessions?
well organized and delivered
Interesting but what tasks would you like to run on the background?
thanks for such a great channel. I heard about parallel computing on Linux. could you please teach us some parallel computing stuff? bests
Great content as always! Thanks man :)
Brilliant explanation, Thanks
Excellent explanations, thanks a lot
That was a killer video. Thanks!
Very good. Thanks man. Legend!!!
This is so helpful thank you man, keep it up.

How to know which process in creating is creating log file in linux
thank you so much for clear explanation
i’m writing a virtual operating system that uses lua for processes and opengl for graphics. This was extremely helpful, thanks!
Great stuff. Thanks for this video.
