cg-object-id - get sha1 id of commit or tree associated with given id or head
cg-object-id [-c | -n | -p | -t] [OBJECT_ID]
If the ID is not provided, HEAD is used. The default behavior is to show the commit ID.
Get ID of commit matching the object ID (error out if it is not a commit). This is the default if you do not pass any parameter as well, but that is only for the human usage. For clarity, all scripted usage of cg-object-id should use -c explicitly if it wants a commit.
Normalize only - don't check the object type.
Get ID of the first parent commit of a given revision or HEAD. NOTE: Multiple SHA1s separated by newlines will be returned for commits with multiple parents.
Get ID of tree associated with given commit or HEAD.
An ID resolving to a commit.
Print usage help.
