What is a Detached HEAD state in Git and how do you fix it?
❓ Interview Prompt: Explain Detached HEAD state, checking out commit hashes directly, lost commit risks, and returning to named branch pointers.
Detached HEAD occurs when HEAD points directly to a specific commit SHA hash rather than a named branch pointer (e.g. git checkout a1b2c3d). Preserve experimental commits by running git switch -c <new-branch>.
Code Implementation Example
bash
git checkout a1b2c3d
git switch main
git switch -c experiment-branch💡Understanding and resolving Detached HEAD states.
🎯 Interview Key Takeaway
Detached HEAD occurs when checking out commit hashes directly. Preserve commits by running git switch -c <new-branch>.
