Change the name of the default branch created by git init

Suppose you want the default branch name created by git init (or tools that shell out to it, like cargo new) to be something other than master. In this example, I'll call it develop.

1. Add the following to your .gitconfig:

   [init]
       templateDir = ~/.config/git/template/

# strings to look for in our file
# Note: you could just parse the whole file. But if you put in a bad password your IP 
# could end up on the bad guy list
declare -a badstrings=("Failed password for invalid user"
                "input_userauth_request: invalid user"
                "pam_unix(sshd:auth): check pass; user unknown"
                "input_userauth_request: invalid user"
                "does not map back to the address"
                "pam_unix(sshd:auth): authentication failure"

Rename a git tag old to new:

git tag new old
git tag -d old
git push origin :refs/tags/old
git push --tags

The colon in the push command removes the tag from the remote repository. If you don't do this, git will create the old tag on your machine when you pull.
