change branches in git code example

Example 1: how to swap branch git

[git checkout "branch_name"]

is another way to say:

[git checkout -b branch_name origin/branch_name]

in case "branch_name" exists only remotely.

[git checkout -b branch_name origin/branch_name] is useful in case you have multiple remotes.

Regarding [git checkout origin 'another_branch'] I'm not sure this is possible, AFAK you can do this using "fetch" command -- [git fetch origin 'another_branch']

Example 2: git switch branch

git switch <branch_name>

git checkout <branch_name>

Example 3: git change branch

git checkout <<branchName>>

Example 4: github go to a branch

git checkout <name>

Example 5: sitch a branch command line

$ git branch

Example 6: how to switch to another branch in git

Github branch 
pull request in branch
