checkout

• Checkout a commit or branch
• Git changes the value of the HEAD located in .git/HEAD
• Practically Files are taken from git repository and placed into working directory and staging area

• Travel between different versions of the project (commits or branches)

# Go to commit
git checkout "commit-hash"

# Go to branch
git checkout "branch-name"
git checkout "-" # go to the previous branch you were working on
git checkout -b "brach-name" # Create branch if not exists
git checkout -b "local-branch" "remote-branch" # Track remote branch (or git checkout branch-name)

# Checkout to head references
git checkout "HEAD@{6}" # 6 heads back
