grep stands for '-g-lobally search for a -r-egular -e-xpression and -p-rint out matched lines'.

Wow thanks

Seriously, man, you should become a teacher. Much thanks.

Incredible. I wish all tutorials were this clear and concise. You go from blackboard teaching to ACTUAL coding and break it down piece by piece. Not copy-pasting code with barely any explanation of what is going on within the code. Keep it up, Jason!

Best video on regexp, clean and concise, thankyou very much!!

I had been searching for something that would explain grep, sed, and regular expression for so long, and no resource made much sense, but you made everything so clear and easy to understand. Thanks so much :)

This video series is one of the best I've ever seen. Thanks so much for your approach. Hope to see more someday!

literally , the best straight to the point tutorial soo far

Beautifully done. Thanks so much for sharing your expertise. Totally worth watching.

Thank you for the lesson, just what I needed! Very well done Sir!

Amazing amazing tutorial!! Anytime I forget grep I will come back here. Many thanks!!

Thanks Jason , really cleared most of the things in on Reg-ex. really appreciate your time on this..

8:56 > _"color coded command line is we can actually see [matches]"_ for those wondering, it actually is achieved by doing this (if wanted persistently, then in the bashrc file): alias grep='grep --color'

Thanks a lot for this lesson, I was afraid of even getting started with learning RegEx and this video helped me remove those fears.

Hey I just spent 30 worth while minutes practicing Regular Expressions. well compiled lecture. Thank you Jason

You are the best teacher ever, simple and to the point. If you were a girl I would have kissed you.

Helped me so much. Taking an online course with no videos and this just saved me.

Just a magnificent teacher. Thx from Argentina my friend!

Thanks jason... Well compiled and explained tutorial. Cleared many of my doubts on regular exp... Many thanks

Thumbs up. Thanks to people like you, people are able to get smarter in computer science.

Very informative tutorial..I was giving a practice mock interview to my husband and i could answer most of the questions correct. Thanks man. bless you

You sir are one hell of a teacher!!

Jason. Your video on REX is really helpful, really appreciate it.

This was really good. Thanks for this.

Amazing lesson Jason. Well done I will subscribe and give you thumbs up. Well done loved it

The perfect explanation I wish you were my professor.

Thanks a lot! I'm studying for the CompTIA Linux exam and I have trouble understanding regular expressions. I'm gonna practice a lot, your video made it much easier to understand.

Thank you, this helped a lot. Truly awesome.

One of the best tutorials in Linux

grep stands for g/re/p which is the basic pattern form where 'g' means 'global' (not 'get'), 're' means regular expression and 'p' means print. This goes back to the early days of Unix before even System V I believe.

There is a Computerphile video with Brian Kernighan talking about this.

Very good video even though it's an oldie. It would be so great to have an update on this with more of sed and awk :-p

great video...

Thanks, even after few years i love to still learn stuff. Suggestion: maybe have the files you use in the examples available somewhere (put them online somewhere then archive with internet archive to make sure they are available forever)

Just installed Linux subsystem and found this very helpful, because I used for number of years 'Windows' , didn't know to type single command in a shell, okay maybe some. Some commands match - some not at all. Thank you. * I have to mention since Ii use linux scripts I see better staff on a monitor! :) + there is a couple more sites in a search experience.

thanks a lot !!

nice tutorial! thanks

Why this playlist has stopped in between. We want a whole playlist with more videos on Linux kernel. You are such an awesome teacher :0

Thankyou for this.

THANKS A LOT HOMIE

A doctor who fan right there.

very concise and helpful

Very good tutorial.Thank you! Just one question: Is there anything wrong if I surround my pattern with double quotes even if I don't use some special characters?

Nice content

Go Jason go Jason!!!!

Are you usually a trainger? You got great tone, vibe and way. Thank you for this :D

I still wonder why there is no abbreviated character class for vowels, like [[:vowel:]]

7:45 We'll use grep until it breaks (and then we'll use egrep). 9:21 Put double quotes to avoid some non-standard character of our regex being interpreted by the shell like actually shouldn't. 34:06 The sed command filters daa for editing.

30:59 curly brackets are parrt of the extended grep. POINT NOTED

Another though. if we use webscraping or wget the entire page, just above the buffer saved. we can regex the entire source for emails

I wonder if there is an advantage in using "-P", the perl-like regexes with grep.

cool voice

Thanks

nice.

When you wc -w some text of exactly 1000 words you get 1000 as a result. However when you split the same text with grep into individual words you get 1040 words because grep is splitting off the ‘s and ‘t from words like • he’s • there’s • don’t • won’t • etc. when you do • cat input_file | grep -oE '\w{1,} ' Is there a way to make grep behave like wc, or do we have to use a different strategy for getting the right (desired) result? Any ideas?

Do you have any advanced Sed tutorials? The web is overflowing with intros and basics

👍👍👍👍👍👍

Is there a CLI dictionary available for Mac Terminal?

This is really a good vid. I stopped at the half way point, but plan to continue tomorrow. Thanks for sharing.

Only one "complaint" a backslash is not a slash. ;)

How could I grep email addresses and simply return the domain name part behind the “@“?

Why was it necessary to keep $ at the end of the email and ^ at the start ? Will it not work with those characters ?

Great video! My only suggestion would be to pick one standard and stay with it. Example, only teach the "[0-9][a-z]" stuff. Don't include examples with the "/d /w" stuff. It just confused me.

where could find my dictionary in centos 7-x86

dog - dog = dog ok got it

Can anyone help me to give numbers not alphanumericals

16:57 > _"\d Not standard in grep"_ aahhhhh!!! msys2's GNU grep 3.0 doesn't has this :)

so the sed command doesn't change the real file, only give you the results with the replaced item you asked for.

sed does the change but an option of -e has to be specified before.

Very nice video! I want my file to have the project name and version. How do you this with mv? I dont have and cannot install rename. mv project-3.2-jar-with-dependencies.jar ??????? goal: project-3.2.jar

Kang bli ngerti ngacung bae...

You can pull this to ur github and add it to video for further references : github.com/zeeshanu/learn-regex

I guess we can use awk language. The spectrum would be wide!! ]

I would turn into gay just to marry you, very good video!!

Grap "//d" /path/

Great video, thank you
