Migrate Master To Main

Description:

This post is documents how I updated my git repositories to rename from master to main and to update terminology when explaining things to IT people. See here and here for a background.

To Resolve:

1. First, for each repo on your computer, cd into the repo and run:

   # Step 1 
   # create main branch locally, taking the history from master
   git branch -m master main
   
   # Step 2 
   # push the new local main branch to the remote repo (GitHub) 
   git push -u origin main
   
   # Step 3
   # switch the current HEAD to the main branch
   git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/main
   
   # Step 4
   # change the default branch on GitHub to main
   # https://docs.github.com/en/github/administering-a-repository/setting-the-default-branch
   
   # Step 5
   # delete the master branch on the remote
   git push origin --delete master
   

2. Keep a mental note to use the new terms:

   master => main
   slave => secondary
   whitelist => allowlist
   blacklist => blocklist
