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"
|
|
|
