Chapter 16 ■ Using Git
After executing the commit command, you should see a long list of messages that new nodes were
created in your Git repository, one message per file committed. If you execute the git status command,
you should see that everything is up to date:
# On branch master
nothing to commit, working directory clean
At this point we’ve committed the files and now have the ability to revert files to the state they were in
when we committed them a few moments ago. The next step in the process is adding changes to files and
committing those changes. Let’s make a change to an existing file and add a new file to see how Git responds
to both situations. First, create a new file in your sites/default/files directory. For demonstration purposes,
create a new file named test.txt with a few lines of information so we can see Git in action. After creating the
file, execute git status to verify that Git recognized the new file. You should see output similar to
# On branch master
# Untracked files:
# (use "git add ..." to include in what will be committed)
#
# test.txt
So let’s follow the instruction and use git add test.txt to add the file to Git. After adding the file, use
git status to check to see that the file was added. You should see output similar to
# On branch master
# Changes to be committed:
# (use "git reset HEAD ..." to unstage)
#
# new file: test.txt
#
where new file: was prepended to the file name to indicate that Git is now tracking that file.
Let’s commit the new file to the repository so we have the ability to revert to the current state in the
future. Use the following to commit the file:
git commit –m "committing the initial version of test.txt to the repository"
After committing, run git status to see that everything is committed. You should see the message
stating that there is nothing to commit.
Let’s now change the test.txt file by adding more information to it to see if Git sees the changes to the
file. After adding text to your file, run git status. You should see a message similar to
# On branch master
# Changes not staged for commit:
# (use "git add ..." to update what will be committed)
# (use "git checkout -- ..." to discard changes in working directory)
#
# modified: test.txt
#
