lab 8 Committing Changes


Commit the change

Ok, enough about staging. Let’s commit what we have staged to the repository.

When you used git commit previously to commit the initial version of the hello.rb file to the repository, you included the -m flag that gave a comment on the command line. The commit command will allow you to interactively edit a comment for the commit. Let’s try that now.

If you omit the -m flag from the command line, git will pop you into the editor of your choice. The editor is chosen from the following list (in priority order):

I have the EDITOR variable set to emacsclient.

So commit now and check the status.


git commit

You should see the following in your editor:


# Please enter the commit message for your changes. Lines starting
# with '#' will be ignored, and an empty message aborts the commit.
# On branch main
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#	modified:   hello.rb

On the first line, enter the comment: “Using ARGV”. Save the file and exit the editor. You should see …


git commit
Waiting for Emacs...
[main 569aa96] Using ARGV
 1 files changed, 1 insertions(+), 1 deletions(-)

The “Waiting for Emacs…” line comes from the emacsclient program which sends the file to a running emacs program and waits for the file to be closed. The rest of the output is the standard commit messages.

Check the status

Finally let’s check the status again.


git status

You should see …


$ git status
On branch main
nothing to commit, working tree clean

The working directory is clean and ready for you to continue.
