What am I doing wrong? Recall that the -p in cat-file means "pretty" (-print). The data that makes up a tree object is far from pretty, hence, you can't feed it into git hash-object directly. You can either turn the pretty-printed input into a tree object git cat-file -p $treeoid | git mktree or hash the raw data git cat-file tree $treeoid | git hash-object -t tree --stdin -- Hannes
