The cat Command in Linux (Featuring Real Cats) - Linux Crash Course Series

[@AquariusTurtle]

Thumbs up for cats in the video. In fact, I will thumbs up every video with cat photos on it, even though I already thumbs up all the videos. But, it's well known that cat photos increase your traffic 60% of the time, every time.

[@LearnLinuxTV]

I never knew that, thanks!

This was clever. Made me laugh. :)

[@annalinneajohansson]

As a cat lady AND Linux pupil this is simply the best of both worlds. 🤘

[@synen]

I'm afraid we now need a video on the bat command, quite apt for Halloween :)

[@annalinneajohansson]

I'm jealous I didn't think of that first. 😂

[@lawrencedoliveiro9104]

I don’t have that one on my Debian system. What does it do?

[@costa2016]

Very nice. I recently learned about "tac",which is cat backwards. It seems a joke, but it works

[@edwardmacnab354]

Oh those Unix guys

[@x0rZ15t]

Using cat in combination with grep in stead of just using grep on a file is often referred to as "cat abuse"! The more you know :)

[@enriquezurita4784]

This Episode is so simple as it is fun !!! Wonderful video Jay!!

[@LearnLinuxTV]

Thank you, I'm glad you liked it!

[@damianpodgorski6977]

Great staff! As a an experienced beginner in Linux I did not expect to learn something new but to my suprise I indeed learnt yet another way to use CAT

[@LearnLinuxTV]

Glad it was helpful!

[@mhegyi2]

I just took the plunge using Arch for my daily driver. Most of my career was Windows. Little things like this are refreshers of what I partially picked up from the Linux teams, but now have a much more firm understanding. Thanks!

[@barspinoza]

Did you stay with Arch? How was the experience?

[@tonyravindran]

Good informative video I found two more use cases cat /dev/null > # clears all the contents of the file tac # displays the file in the reverse order

[@sabrinadobbins875]

This was AWESOME! Thank you! Super easy to digest!

[@peterwassmuth4014]

Awesome as always! I'm installed LM21 on a brand new laptop, and my god it works totally fantastic! Slowly windows is out for good.

[@LearnLinuxTV]

Congratulations!

[@peterjansen4826]

Take a wild guess what the tac-command does, guys.

[@lawrencedoliveiro9104]

It dispenses mint-flavoured treats! No?

[@faustipez]

Ok. I'm all for these featured videos, I love them and of course I learn a lot ‼️ ❤️ Hope we see some Halloween and Japanese edition. By the way, I love seeing your Karate badge or whatever the Japanese kanjis are behind you, they are so damn cool 🔥❤️🙏

[@luciusrex]

this is the best cat video on the internet about linux lol

[@alex11943]

Can't read your thumbnail, it says The cat command featuring REA10:06

[@lawrencedoliveiro9104]

Count the #uuoc instances: 6:21 7:56 8:43 Did I miss any?

[@GaiosX]

Now we need the bat command (Featuring Real Bats)

[@Esteban7GT]

Future collaboration with Veronica Explains?!? That would be awesome! 😁

[@linuxgameplayxp6246]

Purrfect video. Thanks.

[@kellingc]

I love the title.

[@jonathanchevallier7046]

Thank you for this explanations Jay. Can you explain the dog command now ? ;-)

[@astralfoxy1787]

Guide starts at 3:25

[@gpop444]

"Cat video" - Love it

[@d00dEEE]

A good followup would be to show bash's "heredoc" feature (I'm reminded of this because I just used it with cat to extend an existing file). Looks something like this: cat >> old_file

[@lawrencedoliveiro9104]

So, you have discovered how to use TWO less-than signs ... have you tried THREE?

[@d00dEEE]

@@lawrencedoliveiro9104 No, three or more are too advanced for me. 😁

[@lawrencedoliveiro9104]

Hint: instead of echo 2 + 2 | bc try bc

[@d00dEEE]

@@lawrencedoliveiro9104 Yeah, bc is my oldest known use of heredoc. I found an old c-shell script that I wrote in 1995 (probably for HP-UX or Irix) with something like this (needed two lines of input, which is why I used heredoc instead of herestring). set pct=`bc`

[@lawrencedoliveiro9104]

@@d00dEEE set pct=$(bc

[@darklord14]

Was lured in becasue of both cat and cat. Perhaps tac should be introduced together :)

[@Alex-fl2yh]

Are you planning on making a video on the netcat program? 🙂

[@sharathsk7242]

Insightful.

[@Bruces-Eclectic-World]

Awesome video you two, Purrfect... Hahaha To bad there is not a dog command like bark or woof, how about sniff... 😞 (Yes I have cats too) Thanks Jay! LLAP 🖖

[@nymnicholas]

The next video, we need the "bat". You have to do it in a cave for better understanding.

[@edwardmacnab354]

What if I cat an executable file ?

[@mashoodmemon6987]

the real thing starts from 3:25

[@sotecluxan4221]

[@Ryano35]

Why does it take forever to create a file using cat >

[@736939]

Rust version of "Cat" command, "Bat" will replace it ;)

[@mihai6564]

good video

[@billeterk]

Should possibly have mentioned split(1) too. Although not as useful as in the old floppy disk days

[@N0zer0]

Let's not forget about the tac, zcat and netcat commands either.

[@TheJoseppa]

It would have be nice if you explained that the cat command is the opposite of the split command. Because cat is made to repair split files. ;-)

[@pestpatroller]

cat has problems with finding files with spaces in their name. I tried (as root) cat /etc/NetworkManager/system-connections/Auto ssid.nmconnection and it was "cat: /etc/NetworkManager/system-connections/Auto: No such file or directory cat: ssid.nmconnection: No such file or directory" but of course ls -l found them with no problem. I tried quotes and Auto\ ssid.nmconnection, but no joy. I installed batcat and it worked finally.

[@abucketofelves]

It's nice to see nobody banging on about useless use of cat in the comments.

[@tmrmotta]

Thankss

[@fugoogle_was_already_taken]

I know 'cat', but clicked anyway for the cats

[@chillnacho]

I love cats and I love Linux, but showing pictures of cats during the tutorial was a bit distracting for me. Just an opinion, but still a great video.

[@70shahin]

Please a grep video with Ral Greps :|

[@saraban5rivers]

what a catastrophe

[@moralfuxery]

I don't understand why people subscribe to these services. I have a VM of any OS I want on my Mac. Kali/Win10/Whois, etc. I get it takes wayyy less resources, but you get it basically for free, and the power of the entire OS. But I just use it to learn through my degree. I guess for DevOps it'd be different though.

[@TheErixcode]

I use cat to dump of images using cat, also in one ctf I used cat to get shell😂🤓

[@miss-astronomikal-mcmxcvii]

I love cats! :)

[@Ollital]

I like cat. And cats too.

[@act.13.41]

Unlike the useless cats running around in the yard, the cat command is actually useful.

[@keylanoslokj1806]

3:30 minutes of fluff before you get to the lesson content? Bad decision. It should begin in the first 20 seconds max

[@N0zer0]

Piping cat into grep, wc, etc. is pointless most of the time as these commands can take filenames directly. To view file content in the shell it's better to use less.

This was bad for both cat lovers and developers. Images popping up ruin the experience and you don’t really get the benefit of looking at cats 👎
