Navigating through the folder structure in Linux is easy if you know a few commands. A major issue for many technicians is that Linux cares about capitalization (FOLDER != folder), and using / with the cd command causes Linux to look for the folder in the System Root.

Notes

Capitalization matters in navigation. “FOLDER” is different than “Folder”. You can have 4 separate folders named: FOLDER, Folder, folder, foldeR.
when using cd to go into a lower level folder DO NOT use /. If you are in the “home” folder and want to go into the “bob” folder you would type “cd bob” NOT “cd /bob”
Find Where You Are

The “pwd” command tells you your location in the folder structure

Changing Directories

The basic command to change directories is “cd”.
“cd ..” moves you up one folder level.
“/” represents the system root.
From the “home” folder you could use “cd” like this:
cd ..
cd bob
cd /
cd /home/bob
Listing Folder Contents with “ls”

“ls” lists the contents of a folder
“ls -l” lists contents of a folder and displays ownership and permissions
“ls -lh” is the same as “ls -l” but formats the file sizes to be easier to read.

“Mommy, where am I in this operating system?” I laughed so hard at this Eli. Thanks for the videos. I wouldn’t consider myself a beginner but you always seem to have some insight on even the easiest of topics that I had not thought of before.

forward slash is root unless you put a . in front of it . which means the current directory so ./bob would be the current directory + /bot

I thought the only difference between windows and Linux command line was vs / . Now if I could just keep clicking on stuff pretty sure it would eventually work

I'm grateful that you're doing these videos. Especially as I've just downloaded Ubuntu Desktop and don't have any clue. I just wish there was a permanent fix to adjust my Logitech mouse speed. It's slowwwww. (I used solaar to enable the mouse) and used Tweaks to adjust the pointer speed, but still slow.

Dude, I'm so glad you're making these kinds of videos again. I'm pretty sure your older videos on Windows Server and networking helped me get jobs because I was so well versed for my interviews.

Hey Eli, i didn't know how to reach out to you and send you a PM so i'll just post it as a comment.

You don't get an idea how useful your videos are, they're also a lot of fun! I think I watched your first videos like 8 years ago and found them quite helpful when I was starting my career as a Linux Engineer/SysAdmin. For the last 2 weeks I found myself playing some of your content and learning stuff here and there, also your insights for some of the topics are hilarious (choosing a linux distro and all that) love it when you mock hardcore fanboys a little.

Anyways, I can also tell you're struggling making money out of youtube or your website so the least I can say is THANK YOU for sharing your knowledge with us all. One last thing… Could you consider making a video about the struggles of being a Linux Engineer/working in IT? I've personally been struggling a lot lately, thinking "I'm not good enough" (i'm in my late 20s, 5 years of experience) and after doing some research I found out this actually happens to A LOT of IT people, there's always some new technology coming up and it's hard to keep up with everything and there's always a lot of people who are better at what you do so it can be quite frustrating. Some call it "Impostor syndrome". Cheers!
