Linux and macOS Command Line Basics

There's some foundational command line stuff that you should be aware of, but once you know how all it works, you'll find that it's quite useful.

Hope you enjoyed the video!

A little misspeak... `cd ..` takes you UP one directory, not technically BACK to the PREVIOUS. If you step down directory by directory, going up and back are the same thing. But, you can `cd` anywhere with a valid path argument. If you are in /home/brian/demos, `cd /home/brian/files/videos/uploads_for_youtube`, then `cd ..`, you will be in /home/brian/files/videos. `cd -` takes you back to the actual previous directory.

LOL at the "rm -rf" reflex at 8:17 :D Keep up the good work!

I wanted to thank you for this video. I have seen many commands and they seem confusing but you made it appear easy. I literally typed commands on Mac and Linux as I listened to and watched your video. Very informative.

I've learned more about python and linux after 30 minutes of watching your videos than I have in hours of reading forums and how-to's

I like “sudo !!” for running a command where I forgot sudo.

I still remember "less is more, more is less" I amended "less is more, more is less, but if more is less why would anyone wanna use more?" 😂
Great vid as usual!

You should do an advanced terminal commands video

[brainplot]

`less` (and pretty sure `nano` as well) can also scroll up and down using J and K or CTRL+N and CTRL+P, which are the vi and emacs bindings respectively. Some people may find it easier/more natural that way, compared to arrow keys :)

timely video as, i am relearning shell stuff right now. finding it easier to learn fish and have also read good things about the openbsd ksh.

Hello I am just starting to learn Linux. I am having a problem when I’ll type a command and I guess it was the wrong command and it brings me down to a blank line If that makes any sense. Is there anyway to go back up a line in Linux?

[DailyBeatings]

You can also re-run the command in history with an exclamation point in-front of the line number. So I can re-run "nano text.json" with "!1089". If you want to run the command as root then it's "sudo !1089". Behold, the power of *nix.

Lots of great info. Thank for posting this.

What theme you using for your terminal.. Directory colors are showing different.. I would like to use same

[celestialbeing]

A decent introduction. You said just the surface sheesh. So mkdir is basically making a folder, touch making a text document. Question were you doing these commands through tmux or was it straight shell commands?

[VulcanOnWheels]

4:34 I would have called it the "parent directory."

[tommyshon]

I just need to ask... what linux distro or terminal do u use? I discovered u today and watched few of your videos and absolutely love that “programme” which u use for your programming, can you please tell me which one is it?

[pandabuddy]

Thanks. Hello man. Have very differences between line commands of Linux and Mac?

[PCCenterNetworkSolution]

Long time viewer here from the philippines... quick question.. can i open ADB or debugging option on andriod using shell command?

[halfpint]

At 11:47 you put a colon after brian. Does this do anything special? Because I tested it myself with and without it and saw no difference, and was wondering if there was any reasoning behind it. Thanks.

you can also abstract cd .. further by doing cd which will take you up 5 directories (or as many levels as you wish)
