So glad I looked at this tutorial. I've known how to kind of use grep for a while. Some of these options are going to be super helpful to me in the near future. I should have looked in the man pages a long time ago!
Mann....You are a legend...Only few people are out there like you..You really are a gemstone. Thank you soo much for this awesome tutorial brother ❤️ No wasting time, straight to the point. God bless you. Love from Kerala ❤️
Some folks are intelligent and smart but are horrible at teaching. Corey is smart, intelligent and born to be a teacher. While I am going to contribute on patreon right away, you have a gift that you can use to sell your videos at a small price to benefit and educate the population. Amazing
In case any one is having issues with the --with-default-names flag on Mac - it is apparently not available anymore in the latest version of homebrew. One workaround that worked for me is to 1. install the package via "brew install grep"; 2. set up an alias pointing from grep to ggrep. You can do this by adding 'alias grep='ggrep' somewhere in your .bash_profile file. Steps: 1. brew install grep 2. nano ~/.bash_profile 3. (add 'alias grep='ggrep' somewhere in the file and then save it) 4. open new terminal for the change to become effective 5. check with grep -V (should display "ggrep (GNU grep) ...")
Hi corey, well done like always 👍👍 thanks Nevertheless i would like to add a trick if you didn't already know that When you use history and grep you could wrap the g of grep in a square braquets in order to not get the command itself in the output of the matched results... History | [g]rep
Coincidentially, I had just tried out grep yesterday after completing the "Terminus" game. Today my colleague was very impressed when in a matter of seconds, out of 7500 case files, I picked those 40 or so which contained one certain word. also you can export the results easily into a file (I use &>>filename.txt (.csv also works)), which might come in handy if your boss wants "all the contracts with the Miller Company ASAP", or if you want to quickly mail a list of relevant files. As always, great video!
Nice! Yeah, knowing the command line is a great way to do tasks like this and is a lot more time efficient than writing a complete program from scratch to do the same functionality.
I think back to the days where I literally let Windows XP search through "all .doc files, look for existence of expression Blabla" over the whole FRIGGIN WEEKEND! I think back in shame of course :) One day, I will make a video explaining how I turned an unsorted mess of 15 years unsorted .doc files into a searchable database over a weekend and I will refer a lot to you. Thanks man!
This is exactly what I'm looking for, a way to search for a certain word within 10-20K of case files, located on different drives. I usually use mdfind "word" but it doesn't always work on pdf files, do you mind sharing that method/command you used to find those files?
Great video as always. Our company has switched from Windows to Mac, and I find all of these videos supremely helpful while transitioning. Also, I find it interesting that Gnu is pronounced Gah-new when referring to the software, but just "New" when referring to the animal; sort of like Dvorak the composer (pronounced: d(ə)-VOR-zha(h)k) vs Dvorak the professor/keyboard designer I guess. Thanks again!
Glad you find the videos helpful! As far as the pronunciation, if you're interested there's a short clip on this site with the author explaining how he came out with the pronunciation. Kind've humorous and interesting: www.gnu.org/gnu/pronunciation.en.html
@@coreyms Well that is really cool! Thank you for sharing it! Gnu has always been my favorite word choices when playing Hangman with folks for the first time. Almost always wins. :)
Thanks for covering this. Man, do you make things understandable and simple. I wish that I would have just used UA-cam to learn Linux, instead of doing a community college course.
1. one can't use the "\d" for the digit in grep/egrep (if not use "-P") 2. to use "{3}" for "three times" one need to use 'egrep' instead of 'grep' (if not use "-P") 3. there is no option "--with-default-names" 4. => one need to install "brew install grep" and use 'ggrep/gegrep' instead of 'grep/egrep' 5. there is a very useful option "--color" to highlight found items (as well as filenames and row numbers when using GNU grep)
Hey love the video; got a question. Homebrew decided to deprecate the --with-default-names option and I am having trouble finding how to do the same thing as you did with that now gone. Do you have any advice?

Same! Love the no bs
I'd like it even better if he would take just a sec to give a shout-out to the Greatest President That Ever Was or Ever Will Be, Donald J. Trump.

There are very few tutorial which gets straight to the point, this is one of them. Really enjoyed learning, Extremely instructive.
Thank you.
I like how this was explained. Straight to the point and simple, very easy to understand.
I just ended up watching your Python OOP series. and i randomly looked for some Linux tutorials, and i was SOOO happy to see your name!
Brilliant.
Thank you for taking the time to help me understand grep, I really appreciate your thoughtfulness Corey.
outstanding !!!. Dear Corey, appreciate for your time posting your tutorials. I am enjoying teaching style. Thanks again!!

Great video ! Great explanation. I like that it goes beyond the basic use. Thank you for sharing.
You've made learning these commands so easy, great job and thank you!
Great tutorial. Now I understand the grep command much better and I'm looking forward to understand more about regular expressions. Thank You !
Excellent. Straight to the point. Concise and precise. Love it 🤩

Thanks for creating this video, have been searching on how bash commands filter text files, can't find anything helpful, glad I searched it on UA-cam.
I love your tutorials. Really enjoyable. Thanks a bunch.
Another awesome video from one of the greatest online tutors.. Hats off, corey. With lots of Love from India :)
Simple and clear. Thank you!
YOU ARE AMAZING ...... DO NOT EVER STOP
excellent video, a good start for grep...much appreciated
Nice tutorial, I see there''s also a find tutorial too. I'll check it out. I always am confused between both of them
He's really an amazing guy. I watch this even I know this. So addicted.
Suggestion: put an xargs video :-)
Good suggestion! xargs is so useful!
Such a useful and straight forward video! Awesome!
Fantastic video. I learnt some great options today. Thank you very much!
After seeing one video, i am addicted to watch more. Thank you friend
These days I hit like as soon as I click on the video, I know it's going to be awesome anyway :)
awesome video and easy to understand! THANK YOU!
finally a nicely done video on this! Thanks

Ur the best wallh ... sorry for my bad english
Hi corey, well done like always 👍👍 thanks

When you use history and grep you could wrap the g of grep in a square braquets in order to not get the command itself in the output of the matched results...

Excellent tutorial! Thanks a ton for sharing.
I really like your shells theme! Its also a great tutorial!
This video is definitely getting saved for future use
The video is excellent, very clear, I learned a lot

Thank you!! This tutorial is super helpful!!
Just AMAZING! Thank You!!
thank you so much for talking about the BSD grep and GNU grep!! i stuck there for so long ;-;
very easy to understand :) thank you!!
Very well explained! :D
This is very helpful, thank you very much!
Hi Corey, thanks for last bit on Mac BSD grep distinction!
Thank you for this very amazing and concise tutorial. You have summarized everything perfectly! Does . and ./* mean the same thing if I do grep r?
Amazing video, exactly what I wanted
Nicely explained. Thanks!
Corey is simply the best.
YOUR CONTENT IS SO UNDERRATED!! THANK YOU SO MUCH FOR YOUR HELP!!
Continue adding courses, you are awesome man, watching your videos makes it both enjoying and learning
Great video... You could have mentioned about grep -v option too.
It was helpful for me. Thank you
A video of pure perfection
I thinkl you forgot the -v option that matches everything but the pattern!
Anyway, I learn a lot! thanks for your nice video!
Excellent tutorial.
it was rather helpful, great thanks for the contents.
best as always. your videos are superuseful
Once I fell asleep on the keyboard typing grep arguments and it showed me the path to the 5th demension
great tutorial, thanks!
Not sure if you did it purposely but -win is an easy, useful flag to remember
Wonderfully explained
you saved my day sir, thank you so much
Finally a great explanation of GREP for Mac terminal nerds like me! GOLD!
Very nice never bothered to learn it before but great video
awesome explanation tq sir
Brilliant, thank you!
You're the best! Thanks again.
Thank you great video!
