sometimes you just cant skip some contents, this is one those contents.
awesome job sir, thank you very much.
My pleasure!
Words can’t describe how much I’m grateful for what you did
That is so kind thank you
this is an appropiate place for expressing this - why here?
thanks so much sir!
I work as a QA engineer and this video is extremely useful for me!
Thank you
Amazing teacher! I actually retain what Andrew teaches unlike most others! Well done & thankyou
That is so kind of you David, to comment like this. I appreciate it
Sir, you have earned passport to heaven!!!
This is the best service for mankind. Thank you so much sir!
Thank you so much
Great! grep for an hour! Amazing! Thank you for creating all this!
Enjoy!
Another great tutorial, didn't realise you are now doing live broadcast - great stuff.
Many thanks Mr Mallet
its great effort that you r putting here. Kindly keep posting.
Thank you, I will
Thanks 🙏
Thank you sir. I used a tcpdump minus very verbose, then followed you. Good webinar!
Awesome !!!!! loving more and more the CLI :) thanks for sharing this video!
Glad you enjoyed it!
Man this lesson is just flying everywhere…..
At about the 4 minute mark, the question is how to clear the line. Sometime we want to just do a different instruction before the one that we just typed, so it may be worth saving it for later. Press Esc and then # to put the hash mark at the start of the line i.e. comment it out. That also automatically pushes you to the next line in my experience.
thank you for the free training!
Any time!
Great vlog, hope simlar master vlog on awk and sed too
Brilliant.👍
thank you
Really need at this moment. Thank you!!
You're so welcome!
Great lecture!
I skipped through this, arrogantly believing I knew it all, only to overhear the esc-. ("escape-dot") trick. I've never ever heard of that in over 25 years of Linux. Crikey.
If you were as bad as me at typing you will have found this before I am sure :)
On a PC you can use Alt+dot (ie. hold down Alt then press .)
Option+dot also works on a Mac if the terminal (eg. iTerm2) is configured to send Option as the Meta key.
What's the timestamp on it?
I sometimes hate myself for having grown accustomed to using vi mode in bash ('set -o vi')
Things like this come naturally, the dot operator just works as expected.
see ('help bind') and ('man readline')
@@90hijacked , interesting...been using vi mode for 1.5 years and have hated having to get used to not having this invaluable binding, so I just now decided to try and fix, and... although nothing is bound to 'insert-last-argument', it seems "\e_" still works! I'd be interested to know if this works for anyone else using vi mode. A grep for the binding from `bind -P' returned nothing. Mystery[?].
Great video 👍🏿👍🏿 Could you do a video on “single user-mode” please, explain it in detail?
HI Andrew, I have a question regarding words. This is the first time I have used this file, but my question is what would the OS use this file for??? Thanks again another great video, thank you for all you do for this community it is greatly appreciated, all the best sir. Oh one more thing I had to complement you on your new look on the wed site is really looking fantastic.
Used by applications or developers rather than OS. But think of messages you might see about dictionary based passwords. Applications like that will need a dictionary to reference.
Very usefull video before LFCS exam :D I'm waiting for sed and find commands :D

I haven’t been able to find this PDF guide online.
Thanks for this Urban Penguin! Never knew you do weekly webinars, how do I sign up to receive a time & topic about this?
Thanks,

Thanks you can sign up to the mailing list eepurl.com/gdbo19
32:44 why did escape tcp ? You are already using E option
Very usefull video, thx
Thanks for the comment
thanks it was grate
44:16 i don´t understand why i get different outputs from these commands:
grep -Ei '^a.*1$' /usr/share/dict/words
A-1
A1
a1
ASN1
grep -Ei '^a*1$' /usr/share/dict/words
A1
a1
I expected the same output, as the * character is looking for zero or more characters. Why is the same command with the prefixed . giving me more matches ?
Can you upload this video again with increased volume, my laptop's volume and the youtube volume both all the way up I can hardly hear it.
Really think it is not the volume over 400 likes and is ok on my system. And I am deaf in one ear. These are recorded to broadcast sound levels
@@theurbanpenguin Volume problems are normal on laptops, so if most everyone is using a desktop it's fine.
@@ggaston85 let me know the levels you want. They are uk broadcast levels
@@theurbanpenguin Headphone fixed the issue. Thanks.
Still using 7? Hmm like how I haven't upgraded to 20.04 yet. :) No changes to grep in 8 I hope?
Im stuck using bash and grep trying to use curl or wget and just get the stock price for ltc and thats it, i dont need any other page data just the price nnn.nn just 1 decemal and numbers but its not working its confusing me help anyone??? wish sites would make a blank page with just the stock price so it can be got without all the extra crap anyone know how to do this? has to be bash no python please !!!???
I just enter here cause some company charged $ 75 to my account and it says trainingrep and I don't even know what is this. Not me not anyone in my house. Can someone help me please cause I need to recover that money. I don't know what to do. I don't know if there's diferente companies or something.
"Training Rep" is probably the charge, nothing to do with grep.
Good luck Maria
How you say redundancy modules with a bad taste in your mouth for?
were do i get the "PDF" that you are using?

this isnt for new grep users
No smashed piano... Pfft, I'm out.
wtf 1 hour just for grep
You are obviously a regular expression master! :)
I Just like to listen to him, such a pleasant fella
This isn’t just teaching Grep, but it is teaching regular expressions alongside grep. It is aimed at beginners in both grep and regular expressions in general.
