This may be a stupid question but what are some situations in which I would want to create an empty file within a directory?

I understand why I may want to create an empty directory to move files into.

Many thanks in advance

It is not a stupid question. I believe creating the empty file is only the first step. Once we have created the empty file, then we will learn how to populate the file with content in future lessons.

Hello, I have some questions about creating new files with the touch command. In the exercise, we create a .txt file using $ touch keyboard.txt. Had we not specified .txt, what would be the default file type that is created? What other types of files can you create with the touch command? Is it as easy as adding the document file extension, like newfile.psd or newfile.docx?

Thank you!

Honestly, I think the best way to truly know, is to do this yourself! Why not try it out and see for yourself, the output!

Hello,

I ask this question due to the error messages I receive when I create a file, so I am not sure I am doing it correctly.

For example, I created a document “newfile.sketch” and when I try to open this document, I receive an error that states, “The document ‘newfile.sketch’ could not be opened.” I created a “newfile.pages” document, and the error reads, "'newfile.pages’ is damaged and can’t be opened." Finally, I created a “newfile.psd” and receive the error, “Could not open ‘newfile.psd’ because the file is empty.”

In this respect, I’m not sure if I’m doing something wrong when I’m creating the file, or if you are expected to only populate these files in the Terminal. For a document that is visual and design-based — like a Photoshop or Sketch file — I think this may be rather difficult, but would likely be easier for something more text-based like Pages or Word.

I suppose this all leads to me to another, bigger question — Why would we use the Command Line for building websites? I’m taking the Pro Path “Build a Website with HTML, CSS, and Github Pages” and this exercise is part of the “How to Build Websites On Your Own Computer” section. In the unit “Command Line for Building Websites,” we learn how to navigate the terminal, create new files, and create new directories. Still, these are all things that I could have done in Mac Finder or Windows Explorer. So I don’t understand the benefit of using the Terminal for building websites.

For every format, .psd, .sketch and .pages … do you have the recommended software for opening such files? And did you try opening this from the normal mac/windows directory/file manager?

About your other question, it will be the case that as we progress in programming, we will collaborate. You will work with git. This is the reason we learn bash commands such as ls etc. That way, working with git is easier.

I hope this helps.

Thanks for your response! Yes, I have the appropriate software to open each file, and they do not open from the normal Mac Finder.

Thank you for clarifying how learning bash commands is helpful for git!
