I was in the middle of the ‘Touch’ exercise when I got distracted. Without thinking, I entered too many "cc …"s. without meaning to - going all the way back to the ‘/’ when I entered ‘pwd’. Luckily, the previous lesson had the path /home/ccuser/workspace/blog/2014/dec/ (and then I went back to ‘touch’ exercise and it had reset anyway, haha).

Just wondering - is there a way to see the entire file system tree, not just the name of the directory we’re working in?

Codecademy has provided the filesystem for the lesson:

Thanks for responding! I went beyond the blog directory and was stuck in “/” (where the ls showed the options: bin, dev, media, lib, usr etc.) So, I was exploring the “usr” files because 1) I remembered there being a “user” in the pwd somewhere, and 2) I didn’t think to just go back a lesson to find the path. I finally just reset. :slight_smile:

It did have me thinking though - if I wanted to find a specific file’s path, while in the /home directory, (such as home/ccuser/workspace/blog/2014/dec), is there any way to do this? Like a “Find file *2014” that will print directory to 2014, while you’re in the home directory?

You could use the find command to do this. Keep in mind that if you’re searching from the root directory (or any higher-level directory), it will take a very, very long time to find a file.


find path -name "filename"

You’d replace path with where you want your search to occur (e.g. home/ccuser/workspace) and filename with the name of the file (including the filename extension, like .jpg, .mp4, etc.).

Hey, is there a shortcut to get to a previous directory?

e.g I am in: /home/ccuser/workspace/blog/2014/dec/media/tv

and I want to go back to /blog,

Is there another shortcut instead of using cd …/…/…/… ?
Another method instead of having to count the folders back ?

Thank you!

You can use cd ~ to get to the home directory. Whenever you use cd ~, your working directory (for this codecademy lesson) will be changed to /home/ccuser
