[description]
You can point refs to a new location using the same command you use to create them:
git update-ref refs/<refname> <object>
As an exercise, make all refs in this repository point to the tree object!
[setup]
echo hello > hello
echo world > world
BLOB1=$(git hash-object -w hello)
BLOB2=$(git hash-object -w world)
git add .
TREE=$(git write-tree)
COMMIT=$(git commit-tree $TREE -m "Initial commit")
git update-ref refs/a "$BLOB1"
git update-ref refs/b "$COMMIT"
[setup goal]
echo hello > hello
echo world > world
BLOB1=$(git hash-object -w hello)
BLOB2=$(git hash-object -w world)
git add .
TREE=$(git write-tree)
COMMIT=$(git commit-tree $TREE -m "Initial commit")
git update-ref refs/a "$BLOB1"
git update-ref refs/b "$COMMIT"
for REF in $(git for-each-ref --format='%(refname)'); do
git update-ref "$REF" "$TREE"
