Linux Crash Course - Scheduling Tasks with Cron

[@MichaelDude12345]

Thank you Jay! Your videos are always so intuitive. I don't know if you get told this enough, but you have a real gift for teaching. You are a huge help to everyone entering the linux community, and its people like you who help to grow this open source ecosystem by making it more accessible. I have learned a lot from your videos and it happened a lot quicker than I thought it would.

This video explained so much about scripts running at various times.

Cron is a great tool, has been since the 70's when it came out on Unix V6. I'm glad it's still around.

[@RicardoGarciso-f3y]

Hi Larry, Lucky you were around Unix in the 70's! 😃😘👍

[@mysteriousjungalist]

I can't thank you enough for this channel.

Awesome video about Cron. Jay - You're awesome. Terrific. I love this channel almost as much, as I love Interstellar (2014).

[@ranaellese]

actually, your whole course is really helping I'm not following all of it but when I search for any topic I feel safe when I find your vids :"D

[@guilherme5094]

I like the editing style and thanks Jay.

[@DonnaBussure]

This was a great video! Nicely done and very informative!

[@unbekannter_Nutzer]

The information at around 6:00 is not correct. If dow and dom are specified and don't start with a *, the fields are OR-combined, so the command will run at the 15th of August and at every Friday in August, not only on those 15th of August which happen to fall on a Friday. man 5 crontab says: Note: The day of a command's execution can be specified by two fields - day of month, and day of week. If both fields are restricted (i.e., don't start with *), the command will be run when either field matches the current time. For example, ``30 4 1,15 * 5'' would cause a command to be run at 4:30 am on the 1st and 15th of each month, plus every Friday. One can, however, achieve the desired result by adding a test to the com‐ mand (see the last example in EXAMPLE CRON FILE below). And D.C.s comment about 6:30 is correct, too, but I guess that was a mistake of attention, not information.

[@caveman1226]

6:30 "* 11 * * *" = every minute of the 11th hour, not "at 11am." That would be "0 11 * * *"

[@babasholaodunaike1759]

yep

[@ChuckBoecking]

Great job! I believe that editing /etc/crontab is best practice on servers. That way you can see all jobs in one place.

[@chillnacho]

Awesome video! I have so many ideas for this. Thanks for the great tutorial.

[@dustinhess6798]

Thanks again for another great video. I have learned so much watching your channel.

[@ThomasFaller]

Cron is possibly the best feature in the Linux ecosystem.

[@jonneymendoza]

windows has something similar

[@ThomasFaller]

@@jonneymendoza yeah task scheduler is not bad

[@saidneder41]

Loving the new intro and thumbnails!

[@udayarpandey3937]

You are doing a great job sir. Keep serving the society.

[@michaelwright2986]

Thank you very much. I just need to schedule a single task: for oncers like this, graphic front ends are useful, but I can't find one. This video makes me feel comfortable about going back to where I started, editing text files. This video is very clear and confidence inspiring.

[@moamenabdelkawy5718]

You're a great explainer Jay. Thank you.

[@iandron7119]

Excellent. You make it crystal clear.

[@Hobbitstomper]

A quick mention on how to set a cronjob every X amount of hours (i.e 0 */4 * * *) would have been great, as beginners might think that this is not possible.

[@blasdelezoyolavarrieta7346]

[@ultron7461]

Your all videos are Awesome. Thank you very much Sir. 😇

[@TopestG-k5m]

Great editing...keeps the focus on, great work

[@umka7536]

I do use cron under user account. There are number of tasks which I need to do only in my home directory. And thanks a lot for @reboot and @hourly tips. I didn't know that.

[@ranaellese]

I don't know it's you or KZbin but I'm really thankful for the Arabic translation

[@AmishaSharma_1]

Very well explained even for the person who never used the cron.. thanks..

[@blahblahlaboratory9381]

Man, you have so many cool videos!

[@keinermendoza4631]

Thanks for sharing the knowledge, this seems like something very very useful.

[@richardracine9055]

You talk at Mach 1.5. Its worth being more deliberate so new people can follow. Thx for the grt video.

[@fortune_hr]

Amazing video, great explanation. thank you

[@normang.827]

Thanks Jay, great explanation!

[@PulpFreePress]

Just what I was looking for…thanks!

[@etiennelabeille]

Great job, Jay.

[@Elliria_home]

Thank you. This was *very* helpful.

[@rcdenis1]

The AT command is like a "one shot" cron job.

[@Matthew_080]

Stunning work!

[@kapilch]

great explanation, Thanks

[@shashikantovhal1769]

Thanks for this tutorial.

[@roacchi]

thanks it helps me solve my problem

[@NoEgg4u]

@6:27 -- Regarding: 11 AM If you set your job for: * 11 * * * echo "hello world" Will the above run once, at the click of 11 AM? Or, will the job run every minute, from 11:00 - 11:59? To have the job run once, at only 11:00, would the entry need to be the following?: 0 11 * * * echo "hello world" Thank you.

[@nevoyu]

Great video, are you going to do a video on systemd timer?

[@theparten]

your screen on the machine in the background is nice...how do set or get one for my pc...

[@terraflops]

the cron job with the echo "hello world" didn't do anything

[@baburakbas5127]

clean and understandable

[@asifadam93]

Nice video man 🙃, thanks

[@tmoumimahmoud6966]

Thank you Man, very helpfull .

[@udhayaraav3490]

Good One easy understanding.

[@bryanthompson1070]

So if I use @daily, what time will it run? Is there a way to set the daily time?

[@bologna3048]

"cron jobs" just sounds so funny

I think it's interesting your using Cron on Pop Os. Because I don't think Cron is installed by default on Pop Os.

[@Bouipi]

14:43 so I dont need to add bash command (bash ~/Documents/blah/blah.sh) as a user?

[@sugabeariadt]

What if you want to run the command every 5 minutes? What would the syntax be for that?

[@Not-THAT-ChrisPratt]

*/5 * * * * Sorry, just saw this (2 months late)

[@Der_Rotsteiner]

I do everything manually (even executing cpu instructions)

[@k.chriscaldwell4141]

If testing with echo, you need to pipe it to wall (“ echo ‘hello’ | wall “) or you won’t see it.

[@Nakim0]

i now understand CRON

[@kevinoconnor1396]

Ok. Noob time. Running Ubuntu 20.04 in WSL - found I had to start the CRON service for CRON jobs to run. Makes sense I guess - but just sayin ... for any other noobs out there like me. Guessing that would be pretty much universal - yeah? Thinkin' you can config the service to autostart ... back down the rabbit hole!

[@s9209122222]

I can't find this command on Arch Linux.

[@AP-ib7rf]

how did you know about august 15th ?

[@vhadzdansalan]

Can you do scp or rsync using cron please

[@noferblatz]

Another issue you didn't cover: it might be anacron rather than cron. I back up using a script I placed in /etc/cron.daily. No editing of a crontab. Just insert the backup script, and cron/anacron will execute it along with every other script in that directory. There are also cron.hourly, cron.weekly and cron.monthly directories.

[@nelsontan]

Hi Jay I'm able to execute a py script via the interpreter and terminal but it just won't run in Cron (be it root or user) even with absolute paths :-(

[@dolodestinations7628]

its so crazy to me that there are no tutorials on how to execute a python script with a cron job. If anyone knows of any tutorials. it would be greatly appreciated.

[@dersinndeslebens9780]

I want to run a batch-job of freefilesync after reboot. I used this command but it doenst work: DISPLAY=:0.0 @reboot /usr/bin/FreeFileSync /home/username/Schreibtisch/Testbatch.ffs_batch where is my mistake?
