I have look through various responses to similar questions but none of the solutions have helped me.
I am getting the error:
"/pc1.startup" E212: Cannot open file for writing
I understand you cannot open a .startup file in notepad and edit it then save it as the .startup extension but I am struggling with finding a way to write the changes to my hard drive. Nano also gives me the same issue. If anyone knows any solutions that would be appreciated.
I would guess that "various responses" have brought these up already, but for lack of detail I can only state the obvious:
Editors (mostly) don't care for file extensions, but the location matters a lot. As you're attempting to write to the root directory (/), you need to be root to be allowed to write there.
As I don't understand why a *.startup file needs to be there, it would be best to store it elsewhere. In Vim, you can do this via :saveas ~/pc1.startup (choosing your home directory instead). If it needs to be there, launch Vim as the root user with sudo vim /pc1.startup instead.
