git-mktree - Build a tree-object from ls-tree formatted text
git mktree [-z] [--missing] [--batch]
Reads standard input in non-recursive ls-tree output format, and creates a tree object. The order of the tree entries is normalized by mktree so pre-sorting the input is not required. The object name of the tree object built is written to the standard output.
Part of the git(1) suite
