git checkout rasp is not magic—it’s a command that switches context in your repository, instantly putting you onto the branch or commit named “rasp.” If “rasp” is a branch, Git points HEAD there and updates your working directory. If it’s a tag or commit reference, you enter detached HEAD state. This can happen without warning if “rasp” is not a branch.
To run it, you must have the target available locally:
git fetch origin rasp
git checkout rasp
If “rasp” doesn’t exist, Git will throw an error. Check with:
git branch --list rasp
git tag --list rasp
Switching with git checkout rasp keeps your index clean only if there are no uncommitted changes blocking the move. To safeguard your work, stash changes before checkout:
git stash
git checkout rasp
git stash pop
This avoids merge conflicts and failed switches. Since git checkout both changes branches and restores files, many teams prefer git switch rasp for clarity—but git checkout rasp remains valid and widely used.
