How to amend changes to your code in your most recent commit – 074

Yesterday’s tip was about making changes to your commit message. Today’s tip is making changes to your code as well.

Hey my Git experts friends reading this! I’m not sure what the command line equivalent is, so can someone look at my section below on using the CLI and tell me why I have to use –allow-empty?

We’ll start with Team Explorer in Visual Studio and then rinse and repeat with what I think is the equivalent git command.

Amend using Visual Studio

It looks like Team Explorer will let you amend based on whatever changes are in the working directory, but just in case you only want to change one file, I’d suggest staging the file(s )you want to amend first. In a command line scenario, whatever files are in staging are the ones that will be amended. (See previous tips)

Actions button in Team Explorer

Click on the Actions button and select Amend Previous Commit.

And you’ll get a new commit ID.

Amend using Command Line

Full disclosure: I don’t know when to use the –allow-empty option. I also don’t know what the ramifications of using it are. It seems I need to use this option even though 1. the staged changes are different than those in the commit history and 2. I’ve specified a commit message. TBH I’m not sure what is going on here.

But this is my best guess at the command line equivalent of what Team Explorer is doing.

  1. make changes to your file
  2. use git add to add those changes to staging
  3. git commit –amend -m “new message” –allow-empty or git commit –amend –allow-empty (but I’m not sure)

The below screenshot shows what happens when I don’t use the –allow-empty option.

git commit --amend -m "new message" wants the --allow-empty even though changes are staged

and here’s what happens when I use the –allow-empty, which turns out to be the behavior I want (or as far as I know!)

git commit -m "update readme" --amend --allow-empty shows success

So yeah, if you know what is going on wrt to the –allow-empty option, please let me know!!

How to amend your most recent commit message on your local repo from the command line – 073

Following yesterday’s tip where you learned how not to panic when presented with a vi editor, today’s tip will cover the scenario of what if you wanted to amend your most recent commit message.

Suppose you had a git commit message “updating readmeee” which you’ve caught immediately. The most straightforward way is git commit -m “new message” –amend

git commit -m "updating readme" --amend updating last commit message

But let’s say you forgot the message flag and now you’re now face-to-face with the vi editor.


star wars it's a trap meme

When vi first opens, your cursor will be in command mode, despite seeing the cursor in the editor. (pssst… it’s a trap)


You’ll want to press The status bar at the bottom will change to show —Insert–


Once you are finished with your edits, hit ESC to enter Command Mode, and then press :wq for write and quit.

and voila, you’ll see in your log that your last commit message has been modified, but the timestamp (and rest of commit history) is still the same.
