A shell script that squashes your commits to a single commit relative to a main branch

Suppose you are working on a feature branch, and because of context-switching, your feature branch contains lots of temporary commits:

Before merging your changes to the main branch, you would like to squash all your changes to a single commit:

With this shell script, you can run:

squash-commits main 'feat: Add new header'

It will squash all of your commits to a single commit with the commit message feat: Add new header right above the main branch!

Installation:

1. Download the squash-commits.sh file to your local computer, and name the file squash-commits.sh

2. Create an alias of this script on your terminal by having:

   alias squash-commits="~/Downloads/squash-commits.sh"

   in your ~/.bash_rc or ~/.zshrc file

3. Reload your terminal by running source ~/.bash_rc or source ~/.zshrc

4. Go to your Git repo, check out to your feature branch, and run:

   squash-commits <base-branch> "<your-commit-message>"

   where:

   • <base-branch> is the branch you want the single commit to be right above
   • <your-commit-message> is your commit message from your code changes
