Hey Shawn, I've been studying for Linux Essentials for about six months or so (I had zero experience with Linux beforehand) and your videos have been a game changer for me! I feel like I learn more from one of your 15min videos than I do from an hour of reading the LPI study guide (nothing against the LPI, but the material's not easy to read through). Thank you so much for making these videos and lending your knowledge to people like me.
I knew most of the commands but I stayed for your enthusiasm and super clear forward explanation, looking forward to dive into your other videos of your channel!
Thanks Shawn, that's a great refresher on pipes and redirects. I hadn't come across 2>&1 before. Good format, having the slides before diving into the command line.
@@jamesc4343 I’m just curious what type of questions are on the exam - are they just asking you to pick the appropriate or type the appropriate command / do they ask about fsf and OsI … there is so little info avalible .. I test on Saturday so any hint will help please 🥺
It is funny I have been using linux on and off for years. Yet I have learned so much from these videos. I have used the 2> /dev/null for years and knew it was to send things to null file but had no idea really how. Your videos are the best.
Thank you so so much for these detailed videos, they are more helpful than you can imagine! Or well, you learnt linux yourself so I'm sure you do imagine. Regardless, thanks again!
Thanks Scott! Like I said in the podcast with Chuck -- it's really great to have multiple teachers covering the same topics. Sometimes a different take works for different people. And usually being taught in multiple ways makes you REALLY understand a topic. :)
The "cat ouptut.txt 2>&1 | less" actually made a lot of sense. Especially as silly as it sounds with the arrows. Your course is super easy to follow and is actually giving me the confidence to work in linux and work on all my linux certificate goals. Thank you for this course. I'm looking forward to you finishing posting your linux plus course.
Hey Shawn, I'd like you to ask about the sequence 12:26-12:34 - you're saying that the stderr is redirected to stdin. I guess you meant to say stdout, right? Happy to hear back!
Hey Shawn love the videos, trying to follow along but whenever I try the "echo "hello" > output.txt command, I get a permission denied response. Not sure what Im doing wrong
You must be in a directory that you do t have permission to write into. Try typing “cd” and enter to get back to your home directory, and give it a try there.
Hey Shawn, I really want to be some kind of Linux system administrator. I’m currently at wgu, and one of my classes includes getting this cert. over the past year of doing Linux I’ve quite enjoyed it. I also currently work in an IT specialist role. I’ve got two years of experience with things like MECM, Active directory etc. do you think there are decent beginner roles in Linux? Or should I peruse other Linux certifications as well?
I must admit, I've never heard that argument before. And I answered Letters to the Editor at Linux Journal for YEARS. (Mainly because most letters were about something I'd written, lol)
That makes sense. In the first instance, you're redirecting STDOUT into less, which will allow you to browse it with the less program. In the second command, you're redirecting STDERR into STDOUT, and then STDOUT into less. The only difference is that if there was an error (like if opout.txt didn't exist), the error would print on the screen in the first example, and it would be displayed inside the less command in the second. Hopefully that makes sense...

planning on taking my exam this Thursday, rewatching some of your videos again... very helpful.. thank you so much man!

Thank you! My hope was that it wasn’t too redundant, but it’s sort of a tough thing to grasp, so I figured slide + hands on might be appropriate.
Ditto. Great refresher on PIPES/REDIRECTS. Very well explained.
still watching these videos exam countdown thank you for these videos. Watching this for the 2nd time right before my exam.
how did you do on your test?
@@softballfj pass not a bad exam. Currently in python course it is no joke.

@@softballfjjust seeing this but yea multiple choice im sure u already passed!
went to your website and read your story. Very moving. You are an inspiration and I pray the Lord continues to bless you and your family.

love this series! This video has me more lost than when I started
Yay! And… oh dear. :) (hopefully the series as a whole is less loss-inducing, lol)
@@shawnp0wers this is a great series. your explanations are great
This is great ! Thank you I'd be lost in my class if it wasn't for your video
I’m so happy to hear that, thank you!

Great content, Shawn . I am starting to understand pipes. It was a better lesson than Network Chuck's on pipes. Gave you a thumbs up!

Would you ever consider doing an LPIC-1 course?

Thanks for this video🎉
I know this is a few months old, but you can pipe stuff places in Windows as well. Doesn’t take away from the coolness of Linux.
Cool!
So if you wanted to make an error log file, would you do “COMMAND 2>> error.txt” for it to not overwrite itself?
Yes, exactly! :)
where did we use the less command before??
شكرا Thanks
What is this heresy?!?!? Pipes = UNIX not L****x!
I must admit, I've never heard that argument before. And I answered Letters to the Editor at Linux Journal for YEARS. (Mainly because most letters were about something I'd written, lol)
Wait, Linux has a journal?
cat opout.txt | less and cat opout.txt 2>&1 | less had the same result for me on ubuntu.
That makes sense. In the first instance, you're redirecting STDOUT into less, which will allow you to browse it with the less program.
In the second command, you're redirecting STDERR into STDOUT, and then STDOUT into less.
