git commit -m “some comment” vs. git commit -a -m “some comment”

What's the difference between these two commands?

git commit -m “some comment”

and

git commit -a -m “some comment”

I'm trying to be clear on this.

my understanding is that -a adds all of the un-added files to the staging area before you commit them. Otherwise it would be a two step process.

Hey Perry,

What two-step process?

The -a flag will add any files modified since the last commit to the staging area right before the commit. It allows you to combine the "git add" with "git commit" into one command. It won't add new files you've created though. For those you need to use git add to add them to the staging area.

Hey Seth,

I thought the -a option stands for "all" and that git commit -m "some comment" is used to commit a version of your code into the repository?

git commit -a will automatically add all modified files in the repository to the staging area AND commit them too, which means with this command you can skip the adding (git add <fileName>). However, git commit commits only files that are explicitly added to the staging area. I hope that was helpful.
