Again, we'll use the data-model repository from the previous example.

For specific file information, we can use the ls-files command to get information about files in the working tree and the staging area. By default, git ls-files will show the files in the staging area, as shown in the following command:

$ git ls-files

another-file.txt
cat-me.txt
hello_world.c

The status command shows the changes between HEAD and staging area and the staging area and working tree. We can try to create a new file and see what happens using the following command:

$ echo 'Just testing.....
