How to fix warning: refname 'feature' is ambiguous in Git

# Show all refs matching the name
git show-ref feature

# Example output showing the conflict:
# a1b2c3d refs/heads/feature
# e4f5a6b refs/tags/feature

# Find all references containing the name
git show-ref | grep feature

# List all branches and tags
git branch -a
git tag -l

# Checkout the branch (not the tag)
git checkout refs/heads/feature

# Checkout the tag (not the branch)
git checkout refs/tags/feature

# Merge using an explicit branch reference
git merge refs/heads/feature

# Compare using explicit references
git diff refs/heads/feature refs/tags/feature

# Set upstream with an explicit remote-tracking reference
git branch --set-upstream-to=refs/remotes/origin/main main

# Use the heads/ prefix for branches
git checkout heads/feature

# Use the tags/ prefix for tags
git checkout tags/feature

# Delete the local tag
git tag -d feature

# If the tag also exists on the remote, delete it there using the refspec form
git push origin :refs/tags/feature

# Equivalent explicit form
git push origin --delete refs/tags/feature

git show-ref feature
# Should now show only one reference

# Compare what each ref points to before deleting
git log -1 refs/heads/feature
git log -1 refs/tags/feature

# Delete the local branch (safe: refuses if unmerged)
git branch -d feature

# If you have verified the work is preserved elsewhere, force-delete
# WARNING: -D discards unmerged commits on this branch. Confirm first.
git branch -D feature

# If it is a remote branch
git push origin --delete feature

# Inspect refs (works for both loose and packed refs)
git for-each-ref | grep feature

# Loose ref files live under .git/refs/
ls -la .git/refs/heads/
ls -la .git/refs/tags/

# Delete a reference safely
git update-ref -d refs/heads/origin/feature

# Rename the local branch
git branch -m feature feature-branch

# Update the remote: push the new name and set upstream
git push origin -u feature-branch

# Delete the old remote branch once the new one exists
git push origin --delete feature

# This creates a local branch literally named 'origin/feature' (wrong)
git branch origin/feature

# This creates a local 'feature' branch tracking the remote (correct)
git checkout feature   # or: git switch feature

# -D is needed because Git treats this as an unmerged branch.
# Confirm with 'git log -1 origin/feature' first; the real remote ref
# is refs/remotes/origin/feature and is unaffected.
git branch -D origin/feature

# Now the short name resolves cleanly
git switch feature

git show-ref | grep feature
# Should show only the expected refs
