In this episode of Linux Crash Course, we take a look at the awk command. With awk, you can leverage its power for the "manipulation of data files, text retrieval and processing, and for prototyping and experimenting with algorithms". In this particular video, we'll cover the basics of awk to get you started.

what's even cooler is look into the history of awk - these foundational core applications have been a part of unix since the 70s. Awk in particular is from 1977.

@nodidog 2 жыл бұрын

I bet the commands took a bit longer to execute in 1977 than the milliseconds that they take today!

So much can be done with awk. An instructor of mine showed us an example where someone had written an entire graphic, first-person-shooter game, like DOOM, using just awk.

So many channels I'm subscribed to have featured the Awk command, but only at a basic level. I would love to see a more advanced tutorial on Sed and Awk.

Awk and Sed are both very useful, even together. I don't even pretend to know much about Awk but I find it fun just to see what output I can get sometimes... Lol Loved the ECHO Echo echo... Nice! I just used the '-F ' yesterday, so you brought a smile to my face, thanks... :-) Just love the Essentials series Jay. Thanks for the video! LLAP

@raughboy188 4 ай бұрын

Awk is incredily powerfull command capable of extending bash script's fuctionality far beyond what bash can normaly do by acting as interpreter. Basicly you can write code in programming language say python for example since python has it's roots in c and execute it in bash via wak because awk can interpret it in a way bash can execute it. Here in particular we have awk {print} where awk is executing print action from let's use python which you can't normaly use in bash instead you do same thing with cat. By using awk in your bash script as i said you can writr small program in c or similar lanugage and awk will as a said interpret it so bash can run it.

Hey Jay, amazing work as always. You are my Master Splinter. I'm guessing that bracket expansion works here as well. I was curious if you thought a dedicated video about bracket expansion would be something that would interest you. Also... A video about Regex would be really neat. I think your approach to teaching works especially well for me and it would be pretty sweet. Also, I should probably check your channel to see if that video already exists. Thanks, Jay!

How would you tell awk to print a range of fields? For example, if you wanted it to print fields $3 through $8? I understand that you can type out $3,$4,$5, etc. But if the range is large, that would be a lot of typing. I am assuming that this is easily done, once you know how to do it. But I cannot figure it out. Please advise. Thank you.

Yes. You can set the "-F" separator as an expression. >printf "this is plain:text" | awk -F'[ :]' '{print $1,$2,$3,$4}' >this is plain text >printf "this=is=plain:text" | awk -F'[=:]' '{print $1,$2,$3,$4}' >this is plain text -GNU AWK 4.1.4 -Debian 10.10

Video starts 01:26 I don't mean to hurt the channel, but seriously, There's a KZfaq ad before the video starts. then there's a 1+ min Linode ad before you say hi, then there's a floating KZfaq ad box over the video. Things like this scare away the followers, and make people prefer to use adblockers and other solutions...

Thanks for the skip button. You can try using the google chrome extension for an ad blocker. It gets rid of ads before and during the video, but it will not be able to do anything against the Linode add at the beginning of the video (obviously).

You can choose to copy an instructor's lesson or you can learn the lesson and apply it towards something else. Learning is a process that requires self-motivation. Your reaction is a clear indication that you don't wish to learn but rather to repeat rotes.
