Linux - Command Line Navigation

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.

ugh!! thank you for taking the time to make these videos. it so basic these concepts, but your candidness makes it refreshingly easy to approach. I used to be so intimidated by Ubuntu lol.

[mitchelvalentino]

Kudos for covering the fundamentals. 👍 👍
And this video is actually watchable, unlike most Linux tutorials. Much appreciated!!

[cartermckenzie]

These videos are fantastic, you have been a huge help. Looking forward to the Raspberry Pi series!

I'm glad Eli covers the elementary stuff that "everyone knows." Well, not everyone knows the elementary stuff; or one suspects the elementary stuff, but need confirmation or refutation (and subsequent correction).

Thanks, Eil!

This command line lesson is really interesting.
Thanks for this lesson Mr. Eli.👍

“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.

[gregorydayton]

You make GREAT videos! You have helped me so much.

The floral arrangement comment made me like the video. Funny

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!

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 (I used solaar to enable the mouse) and used Tweaks to adjust the pointer speed, but still slow.

[abhirathsvlog]

Hi Eli, Can you please make some videos around shell Scripting? Thanks

[caseywinters]

Could create an alias to do whatever arguments you love with ls

[logangraham]

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

[bbolin]

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

[mstam]

Let's all sit through the ads folks as a token of appreciation <3

[mdd]

Thanks be to Christ for useful tutorials, again, vice that (what seemed like) endless Arduino ...uh, well....crap! :)

[jkane]

Man I sure miss the boring Arduino videos...

[caseywinters]

Im seeing a pattern here. Are you an aspiring florist? A closet botanist? Herbophile perhaps?
