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 Год назад

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

@scottspa74 11 месяцев назад

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.

@SlideRSB 2 года назад

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

@Redwane-Music 2 года назад

great presentation and teaching. I like your sense of humour also, like in echo echo , very clever, but only few can notice that

@stephan6530 2 года назад

@raughboy188 Месяц назад

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 you channel to see if that video already exists. Thanks, Jay!

Is there a way to select multiple values as a field separator for the "-F" parameter? (For example "spaces" AND ":")

@plangephace 2 года назад

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

@NoEgg4u 2 года назад

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.

@NoEgg4u 2 года назад

@Terminalforlife (LL) Your explanation, although appreciated, is too complicated for me.

@RandomNullpointer 2 года назад

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

@nevoyu 2 года назад

The problem is that advertisers like linode comes in and pays for a certain length of time and pays more than the youtube adsense ever will for a Linux channel

@juliobanda931 2 года назад

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).

@Kekimus 2 года назад

@@juliobanda931 you can use sponsor block extension for that.

there is also ublock origin tbh or you can play a video directly via mpv iirc
