First let’s make sure we’re still in the right directory.
You should be in the planets directory.
$ cd ~/planets
Let’s create a file called mars.txt that contains some notes
about the Red Planet’s suitability as a base.
We’ll use nano to edit the file;
you can use whatever editor you like.
In particular, this does not have to be the core.editor you set globally earlier. But remember, the bash command to create or edit a new file will depend on the editor you choose (it might not be nano). For a refresher on text editors, check out “Which Editor?” in The Unix Shell lesson.
$ nano mars.txt
Type the text below into the mars.txt file:
Cold and dry, but everything is my favorite color
Let’s first verify that the file was properly created by running the list command (ls):
$ ls
mars.txt
mars.txt contains a single line, which we can see by running:
$ cat mars.txt
Cold and dry, but everything is my favorite color
If we check the status of our project again, Git tells us that it’s noticed the new file:
$ git status
On branch main
No commits yet
Untracked files:
(use "git add <file>..." to include in what will be committed)
mars.txt
nothing added to commit but untracked files present (use "git add" to track)
The “untracked files” message means that there’s a file in the directory
that Git isn’t keeping track of.
We can tell Git to track a file using git add:
$ git add mars.txt
and then check that the right thing happened:
$ git status
On branch main
No commits yet
Changes to be committed:
(use "git rm --cached <file>..." to unstage)
new file: mars.txt
This indicates git knows it is supposed to keep track of the mars.txt file
