Linux/Mac Terminal Tutorial: Navigating your Filesystem

The Terminal can be an intimidating place for people who are just beginning to learn how to use it. There is a fear that you will type the wrong command and somehow mess everything up.

In this video, we will begin learning how to use the Terminal by navigating through your filesystem. This is a great way to get comfortable within your terminal, because the commands we will be learning won't have any side-effects on your system. You can't accidentally delete files or modify important documents. Learning these basics will provide us with a great starting point for more advanced commands. Let's get started.

Thank you! I'm a Stanford student and took a course on Unix earlier this year, and I can say that your videos totally blow it out of the water!

This man is a gifted teacher. Wish to meet you in person one day Corey. I have missed your tutorials.

[samdavepollard]

Super useful for someone like me who's been a mac user for years and never got to grips with Terminal.
Kind of surprised that this doesn't have way more views.
Oh, and you have Git tutorials, too.
Super easy sub. :-)
Many Thanks for sharing your knowledge.

Thanks helped a-lot. Learning vim and this is making it easier to manage.

summary:
Corey explains how to navigate through the file system in this video.


1. ls
this lists the files and folders in the working directory. With an '-a', it shows the hidden files, and with an '-l', it also shows additional infromation in the long form. Using with '-la' at the end shows all files including the hidden ones, in the long form.
2. pwd
This commmand prints out the working directory
3. cd
An acronym for 'change directory'. You have to type the directory of the file that you want to make it as the working directory, after this. Using an '~' will navigate you to the home directory, and '..' to the parent directory.

This was incredibly helpful! Thank you!

[AlexBrykalov]

Great tutorial. When will new videos in course coming up?
I would like to know about how to find files and text in files via terminal.
And about GREP command

[hurstilthymy]

Hey Corey, how would we set up all the files and directories you have? I really want to follow along these videos as accurately as possible

[IT_TechTutor]

Please share a video on awk and Sed command as well. Thanks in advance

These are a few years old now, but I'm learning a lot from the way they're presented. A quick question. I see the use of / varying. Sometimes its /dir and others it's dir/ What is the different use case for it before or after the directory name??

Regards
John

Toward the end of the video, it wasn't really clear why one should use the tilda (~) at all. You can get to the home directory by just "cd" (as you said) and you could go to cd/Navigation-Demo without the tilda as well. Could you clarify the purpose of the tilda?

[vikasvk]

pwd :- It shows the current dir
ls :- It shows the list of file and folder of current dir
ls -a :- Show list of file and folder as well as hidden files
ls -l :- shows the long file info like permissions, size of file, date etc
ls -la : this combine the ls -a and ls -l
cd ../.. :- back 2 folder
cd folder1/folder2 :- jump 2 folder
cd or cd ~ :- back to root dir

How to change the terminal to that style? I mean the original always show the directory like "username$" instead of "username at ... using -bash in foldername \n$"

[dipamvasani]

Are you going to be making shell scripting tutorials anytime soon ?

[kinjalvora]

quick question I keep on getting errors that the command is not found in my Terminal. Is there some way to resolve this permanently.

[olayodejibrahim]

[egwufidelis]

I’m tried navigating into the virtual no directory but I was getting errors. Please can you help me with a possible command line ?
Below are the command line I used that gave me errors.
“cd VirtualBox VMs”
“cd /Program Files/Oracle/VirtualBox”
“cd /Program Files/Oracle/VirtualBox VMs”

They all gave me errors
