dockerit is a small CLI tool that I have been working on during the start of 2021. It’s intended to make running one off commands and CLI tooling easier in docker. Rather than having to write a long string of parameters for docker run, instead you can just use dockerit. This applies to both CLI usage, but also via bash aliases.
Github provided some advice for renaming branches focused around how this can be done in the UI. But with the Github CLI tool that was also release at the end of 2020 you can programatically make this change too.
The Github CLI tool is called gh. The README for the tool has installation instructions for a variety of platforms. One of the commands that it enables is called api, which can be used to “Make an authenticated GitHub API request”.
The Github API obviously allows you to perform most actions that can be performed by the UI, this we can use the gh cli tool to rename the branches of repositories.
For example, for the addwiki/addwiki repository, we can rename the master to main branch using the following command:
gh api --method POST repos/addwiki/addwiki/branches/master/rename --field new_name='main'
And you can use such a command in whatever loops etc you want to, to quickly rename a whole bunch of branches in a whole bunch of repositories.
