Linux Crash Course - The "watch" Command

[@kote315]

At work, I used watch to diagnose scales. There were scales that transmitted data to a computer via USB. The program from the manufacturer allowed me to get the weight once, I ran it through watch with a minimum delay (0.1 second) and moved the cable to determine the bad contact. Worth mentioning, in FreeBSD the built-in watch command does something very different. The command from GNU/Linux is called gnu-watch there.

I'll have to see what it is in OpenBSD.

[@Not-THAT-ChrisPratt]

I use the watch command in connection with the sensors command to keep an eye on system temps: 'watch sensors -f' The -f flag puts the output in degrees F, the default is degrees C.

[@wisteela]

That would be very useful.

[@rotflol6666]

watch -n 10 -d is my default goto, with df -h or ls -la

[@wisteela]

I will be making a lot of use of this command. And for fun, a fortune every minute. I love finding out about new commands to me.

Hi from France, Former Linux fighter since RedHat 5.5 where you had to install everything in text mode, I am currently on the Zorin OS 16.2 Core. Thanx for your humour and very serious videos... 😎 Best wishes 2023 🥂🍀

I was gonna recommend you do inotify and incrontab, see someone else also mentioned them. Very important tools on our servers.

[@Goldcrowdnetwork]

Extremely helpful as all of your tutorials have been

[@TradersTradingEdge]

Love this series, thanks Jay. Have a happy Christmas time.

Enjoyed this video! Your channel is a real gem on youtube. Please continue producing such a great content in 2023 :) Happy holidays for you and your family

[@Not-THAT-ChrisPratt]

Great video, as always, Jay! I realized something when you ran 'watch free -h' and you did not go into the details about the free command. Your videos follow one of the Unix principles: Do one thing and do it well. All your videos follow this, and I appreciate this. ;-) Keep up the great work.

thanks for the video jay

[@remychrist6211]

very good guy , very good videos - Linux is so easy with it - Thank you very much Jay

[@Ranblv]

good video. I might have the courage to start the bash series this weekend.

[@omarcaballero9680]

Very Cool. Thanks

[@Dave-kq7gv]

I enjoyed this tutorial

[@rotflol6666]

use watch to build a custom top-like overview of system resources, files, cluster info or whatever you want to monitor 8-)

[@bobsisic5714]

Can I build a web page or server for all my photos for people to look at , thru a iPad only , or is that what Linode is for?

[@ar_prichan]

really helpful. thank you!

[@sayedsareem]

thank you for these amazing videos!

[@peterjansen4826]

I have been combining watch with sensors for years and of course I aliased it. To see the temperatures of my hardware and the power of my graphics card. Sadly there still is a bug in the drivers for both the fan-rpm (Bad motherboard-support for Linux? The graphics card rpm is shown, the case-fan and CPU-fan RPM are not) and the CPU-power. AMD used to show the CPU-power for Zen2 but quit doing that because it was not always accurate and AMD wanted to prevent users from damaging their hardware because they used wrong data (official communication from AMD).

[@rotflol6666]

have a look at bpytop to do all that for you

[@bobbydigital9323]

I usually use inotifytools to watch files. When my script detects changes it then does a bunch of stuff like load a file to a database.

[@mirlan_sagymbai]

Hello Jay. Can you make some lessons about Linode?

[@leondennis4659]

Can you watch your router traffic?

[@seanfaherty]

Wireshark

[@leondennis4659]

@@seanfaherty Thank you.

[@theshowmanuk]

Cool. Thanks.

[@wesgould1]

This seems very similar to inotifywait /inotifywatch. I wonder if the watch command can be used in a comparable way. I have an inotifywait script running that watches my game screenshots folder then posts new screenshots to discord automatically.

[@hansisbrucker813]

If you use `watch -n 1 -t date` you'll have a clock 😂

[@mihai6564]

thanks

[@farazhassan6417]

Lovely!

[@richardpremeaux4493]

Hey Jay I enjoy your videos. I would like see a video on the tldr command/apt. It would fit right in with your videos. We could do a: tldr watch and read along as you discribe the use of the command. It's a short version of the --man option. Folks if you want to do something crazy try this command: compgen -c. This will print a list of all the commands to the terminal. You will get about 5000 items scrolling up your screen so do a tldr on it first.

[@DL2MBN]

That is so usefull ! :)

[@mickhick95]

Good video

[@krishnapillai6157]

This similar to tail -f command

[@rotflol6666]

watch -n 10 -d 'kubectl get nodes,pods -A -o wide'
