[@TheHermitHacker]

Been a linux user since 1995 but I still learned something. Thank you!

[@EngineerMan]

Glad I could bring you some new knowledge!

[@smudgepost]

Same (1993) Still have trusty Using Linux Sixth Edition (QUE) on my desk..

[@heXan]

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'.

[@AbhishekBM]

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

[@poorgirl9458]

and when you go ‘set -o vi’ to enable vi mode at the bash prompt ‘ctrl-L’ does not work

[@Hakusha]

these linux videos are fantastic

[@zachmane2]

Always appreciate the quality of your videos. Goes in depth, but accessible to beginners

[@EngineerMan]

That's my aim :)

[@Diprotic]

I'm 3 minutes in & I've learned A LOT! Thank you! You're the kind of people we need on youtube regarding linux.

[@maxpolaris99]

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!

[@bitelogger]

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!!!

[@EngineerMan]

My name is Brian :)

[@MehdiShokoohi]

That was amazing Engineer; wish i could 'fg' all of my postponed tasks and "kill -20 bad-mood" !

[@ShivamJha00]

Why not kill -9 it :D

[@justChuka]

U mean 9?

[@kavithapriyacj4868]

Just a wow content .. awesome man that u indirectly mentioned about difference between killed and terminated process ..love u

[@aminebouaita9202]

I want to thank you for the quality of your videos, not just this one. All of your videos

[@EngineerMan]

You're welcome!

[@stargentitude7154]

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!

[@abhishekshah11]

I'm happy that I recognized all the commands :)

[@fruitygranulizer540]

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.

[@EngineerMan]

Glad it helped :)

[@rushikmakwawna]

Very well explained. Keep uploading such videos. Sound clarity is really good.

[@yeeeehaaawbuddy]

These are very involved processes, but you explain it all so well, and in such a good order. Thanks!!

[@justchecking12]

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

[@TheFarmacySeedsNetwork]

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!

[@EngineerMan]

Thank you :)

[@TheFarmacySeedsNetwork]

Thank YOU :)

[@IctioPar]

Great content! I've recently started working with linux again and it's awesome to get to know more!

[@MiserableDuck95]

Where was this 3 months ago during my Operating Systems course?

[@diggydude5229]

You're looking for W. Richard Stevens' books on UNIX programming, where all of this stuff is explained in detail.

[@ChudLife]

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

[@aayyaa1188]

You make the concept of these command so clear. Thank you soooo much

[@freeuyghur2063]

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.

[@brandon.duffany]

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

[@tigercake558]

really love these videos, I'm learning a lot. Very very accessible and clear videos, please keep up the good work.

[@skyloreBOTS]

Dude props on how well you explain everything!

[@patrykp8460]

after watching 15 sec I knew that this is proper and what I was actually looking for :D

[@georgichelenkov4360]

Great job! Recently found these series and am fascinated! Subscribed immediately! Keep up the good work!

[@somber_soul]

Very helpful. I've only ever seen htop for process management and this helps to understand the underlying signals being sent. Thanks!

[@wramarante]

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.

[@EngineerMan]

:) Welcome.

[@ZacKoch]

Great as usual!

[@alexanderradyuk9204]

Good job 👍🏻 The way you explain is awesome. Even knowing such things I continued watching. Keep it up!

[@EngineerMan]

Thanks for the kind words, hope I helped in some way.

[@4932gb]

Been using unux since 1980 and linux sice 1995. This is good stuff!

[@vaibhavppandey]

Wow :O

[@gana706]

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 )

[@MichaelMantion]

You are a life saver. You are exactly what I need right now. TY.

[@zgredfryd]

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.

[@josephemmanuel4089]

Thank you. This really helps me for my current project

[@v0idvlr1]

Learned too much with this video, thanks too much man!

[@tdkiran]

Thanks you for this video . Would like to see more on Linux/unix series

[@naveenagarwal287]

It's funny that kill can also bring a process to life as well.

[@ezequiel9055]

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.

[@tpaq]

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".

[@prabodh11]

Great video, Informative, thanks for sharing🙏

[@glikar1]

Superb clarity as usual!

[@qeithwreid7745]

You have taught me that kernel has parent ID of zero. This is the foundational level upon which I shall build many great things.

[@Diprotic]

It's a kernel like a popcorn kernel.

[@qeithwreid7745]

Diprotic there is a grain of truth in that.

[@behruzm]

Excellent explanation of the above terms

[@bzielinski]

Brilliant and simple explanation about kill signals. Thank you.

[@JTKroll12]

really love your videos I learned a lot of stuff about killing

[@leonardodavinci4259]

Exactly what I needed. THANKS!

[@jorgediaz6730]

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.

[@lavellefloyd4639]

I appreciate you sharing wisdom to linux noobs like myself

[@mikefdorst]

Thanks man! You just upgraded my workflow.

[@pierrebouchard4289]

Great video ... Learned a lot ... You're a gentleman and a scholar ...

[@radubojica7888]

They took yerr jobs !!! Great video man btw. I learned some things from this which my Operating Systems teacher didn't teach me. :)

[@RussTeeTrombone]

Thanks so much for these videos. You’re truly a jack of all tech trades.

[@frroossst4267]

Super helpful, super concise, thanks!

[@photopicker]

That was amazingly clear and insightful.

[@natahmad84]

Thanks dude, pretty clear and simple!

[@lawrencedoliveiro9104]

3:36 specifying ps options without a dash is BSD-style syntax. Probably best avoided.

[@yangzhang2303]

Really nice and clear. Would you like to make an video about using strace ?

[@xpkareem]

I learn a lot from your videos. Thanks!

[@MrSURENDRAGAMEBOY]

Better then my teacher :) awesome man

[@bharatdoesstuff]

Also check out pstree, which lets you view processes as a tree, helps you see the forks and execs.

[@MiseryFarm]

I'm really enjoying these videos. Thanks

[@carlpilongo539]

Thank you for teaching us Linux, Programmer Mrbeast

[@hostgrady]

Very interesting, hopefully I can use these in shell scripts for something

[@catorials444]

I love that mr. beast takes up software engineering.

[@vaibhavppandey]

Hehe

[@isaacvv]

Thanks for the videos. Keep them coming!

[@jonassteinberg3779]

well organized and delivered

[@danielmoita6151]

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 :)

[@bludblind]

Clear and concise information. Thank you!

[@mango-opinions]

I have learned something new. Thanks much.

[@fontanot]

great video, you just earned another subscriber

[@mybean1096]

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.

[@unstoppable-ar3292]

Very good. Thanks man. Legend!!!

[@ag.4937]

Brilliant explanation, Thanks

[@ForceHunterHD]

Great linux videos. I hope more are coming cuz i rly want to learn linux

[@davidrmcmahon]

I just like getting the uptime of my pi-hole and Jellyfin server Pi. Two weeks so far, hoping no power blackouts!

[@lawrencedoliveiro9104]

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.

[@MatthewStidham]

That was a killer video. Thanks!

[@SubiqT]

Excellent explanations, thanks a lot

[@roeyleon22]

Very good explenation ! - subscribed :)

[@yura979]

I would never expect young Che Guevara to make such good clean videos. Thanks.

[@EngineerMan]

Lmao.

[@armandnouri8207]

Great video. Why do different jobs listings appear for different bash log-in sessions?

[@Yash-gi4iq]

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...
