Amend commit message in SourceTree

If you’re using Atlassian SourceTree with a git repository and you do a local commit but then realise the message was incorrect, you can amend it before you push it to remote. To set this up, you can create a “Custom Action” in SourceTree:

  1. Tools -> Options -> Custom Actions
  2. Click Add
  3. Set Menu caption, e.g. “Amend commit message”
  4. Select “Open in a separate window” and unselect “Run command silently”
  5. Set Script to run to “git.exe” including path
  6. Set Parameters to “commit –amend”

Now, whenever you want to correct the message on your latest commit, you right-click on the commit, and select “Custom Actions” -> “Amend commit message“. A terminal window will open with a vi editor open with the current commit message at the top of the file (there will also be some instructions with # at the start of each line; you can leave them alone).

If you know vi, you’ll know what to do. Here’s a quick guide:

  • To start editing, press “i” and then edit the message (on the first line of the file).
  • To delete everything on the line, press ESC, followed by “ddO” (this will delete the line and then return you to edit mode to type the new message)
  • To save and quit, press ESC, followed by “:wq
  • To quit without making any changes, press ESC, followed by “:q!
