git checkout

Checkout a branch or paths to the working tree. More information: https://git-scm.com/docs/git-checkout.

• Create and switch to a new branch:

git checkout -b {{branch_name}}

• Create and switch to a new branch based on a specific reference (branch, remote/branch, tag are examples of valid references):

git checkout -b {{branch_name}} {{reference}}

• Switch to an existing local branch:

git checkout {{branch_name}}

• Switch to an existing remote branch:

git checkout --track {{remote_name}}/{{branch_name}}

• Discard all unstaged changes in the current directory (see git reset for more undo-like commands):

git checkout .

• Discard unstaged changes to a given file:

git checkout {{file_name}}

• Replace a file in the current directory with the version of it committed in a given branch:

git checkout {{branch_name}} -- {{file_name}}
