A "branch" is a separate copy (of the files involved in a project) which can be worked on without affecting the original copy.
"Branching" is a concept basic to most version control systems.
Commands

lists local branchesgit branch -r

lists both local and remote branches
Actions:
git branch <name>
creates a new branch called "name", pointing at the current HEAD revisiongit checkout <name>

git checkout -b <name>
accomplishes both of the above in a single command

git branch -d <branch name>
to delete a branch- Note: must be in a different branch
The basic sequence of events for creating a new branch called "test", updating it, then reverting back to the original branch:
git branch test
- create the branchgit checkout test
- switch to it- stage whatever changes you want to include in "test"
- This can include adding any new files you've created for this branch.
git commit -a -m 'made a change'
- commit the change to "test"git checkout master
- switch back to the main branch (removes new files, restores any you deleted)

- 2019-10-07 How To Rename a Local and Remote Git Branch
- Basically: «git branch -m <new_name>» renames the branch locally and doesn't mess with anything upstream. It's like you just created <new_name> and put stuff in it.
- Note: if the branch is not in the local repository, then you just need to git fetch it after the
git checkout <old_name>
. - Also: «git branch -c <new_name>» to copy instead of renaming.
