Clonation permission issue

[alexmplata16]

I cannot change 01_download_data_model.sh because it says that i don't have permission to it. And as you can see in the image, the clonation appears with that symbol. How can I fix it?

I don't know how you ended up with such permission on the directory after git clone.
chmod/chown will fix this permission issue, check how to use them online.
I'm also recommending you to follow some introductory Linux/shell courses.

Closing the issue, linux permission issue from the user side.
