Linux Loops: FOR, WHILE, and UNTIL (Linux+ Objective 3.1.2)
Loops are SO important for a Linux user, because it makes the commandline work FOR you instead of against you.
This video covers WHILE, UNTIL, and FOR loops. The syntax, the methods you can use for looping, and even why you might want to use the various loop constructs. Plus, it's just fun to learn about BASH scripting!
The CompTIA Linux+ objectives are available here: snar.co/plusobjectives

    Wow! The dynamic port forwarding is already cool, but this sshuttle seems even better! I wonder though, this program is needed to be installed locally only? Nothing needs to be setup remotely on ssh servers? Thanks for the video!

    Thanks for creating this video series Shawn! As a Network Engineer looking to upskill and maybe make some career changes I am loving your videos. I do have one question, what is your deciding choice for using rocky for the class over fedora or centos, or even rhel developer option?

    @14.16 Imagine your friend has a car that only they can drive because they own it (analogous to file ownership and permissions). However, your friend decides to set a special feature on their car (SUID) that allows you (and only you) to drive it as if you were the owner when you need to.

    I'd like to thank you so much for your time and passion to teach. I used your playlist along other resources and I passed today - 750/800. I'd love to see you cover the next essentials certifications like security, web development and the new open source in the future.

    I can't even enable SElinux :D Installed a fresh copy of Rocky Linux which came with policycoreutils preinstalled but sestatus showed disabled. There was no config file in /etc/selinux/, but I created one a filled with SELINUX=enforcing/permissive, restarted the system after every change, but still disabled. Uninstalled policycoreutils, restarted the os, installed it again (still no config) file, restarted but still disabled. Installed it on Ubuntu where it created the config file, change the SELINUX value to permissive/enforcing, restarted but it's still disabled.

    • @Recumbent_IT
      @Recumbent_IT 6 дней назад

      Installed CentOS and it also doesn't have the config file and SElinux is disabled by default.

    • @Recumbent_IT
      @Recumbent_IT 6 дней назад

      Found the issue. I was using containers and WSL and apparently SElinux won't work on those. I've just spinned up a linux VM and it's enabled by default.

    I tried to make to the live-stream, but i had a busy morning and ended up loosing track of the time. i enjoy the livestreams. and i don't think i will be able to make it next week. and i have noticed since you changed up the food that the squirrels are not going after them.

    • @shawnp0wers
      @shawnp0wers 8 дней назад

      Yeah, I switched to safflower seeds, because squirrels don’t usually like them. But I ran out, so put regular bird seed in. The squirrels didn’t figure it out before I was able to get more safflower seeds. :)

    You're so right about "almost getting it" feeling. The only part I felt kinda confused was, since on ssh -R (remote one) you are going through 3 machines. The 127.0.0.1 in the second part confuses me on which machine that is for. I'll watch a few more times. Thanks for your videos!

    So I'm going to get straight to it this is pretty much one of the best explanations of what a SSH remote server connection is. Ask somebody that is just starting in this journey which is cybersecurity, I can tell you that I have been looking on documentation to understand how this works but was not able to understand it until today thanks to this guy

    Thanks for the video, Shawn! It's been a year now since this video was made, and I wanted to share something I've observed. Fewer and fewer devices are being packaged with AC power supplies, even if the device has a USB-C "PD" port for additional power. Manufacturers are now just making these devices with USB ports, expecting you to use an existing adapter and a USB cable. Even old Apple adapters still work fine, even if you have to source a USB-A > USB-C charging cable.

    Another Tip! Instead of "> file.sql" use "-r file.sql" that way you don't potentially lose characters due to conversion from utf8.

    question: Regarding the recursive flag for the "rm" command, why is it lowercase 'r' but for the "ls" command it's a capital 'R'? Will those two commands work either way if you switch the casing on the R's?

    The first Brick is perfect for analog modular Synthesizers. 27V Power Supplys are mainly used by old Laptops. And if your polarity of your Barrel Jack Wallwart is wrong you can snap off the connector, reverse its polarity and solder it on again. Use shrinking tubes to seal the solderjoints and make them look professional

    Great video Shawn! I have dabbled with Linux for years, just so many cool things one can do, reading documentation and taking ownership of things. Permissions have always been a challenge but your explanation of sticky but has really helped me. I’ll be sure to check out more of your stuff. Thank you for sharing this info. I ran across it in my udemy course and this help explain things differently.
