Thanks for the replies -- checking the mode bits was the ticket.

I am parsing the output of git-diff-tree to create some code analysis

When a user adds a submodule to a repository, git-diff-tree reports
the SHA1 of the commit from the submodule.
However, if I subsequently try to pass this SHA1 to git-cat-file, or
indeed any other git command I have tried, I receive an error:
error: unable to find b0f8c354b142e27333abd0f175544b71a0cc444e
fatal: Not a valid object name
b0f8c354b142e27333abd0f175544b71a0cc444e
This makes sense to me, since these objects are not stored locally;
they are stored in the submodule repository.
However, is there a simple and reliable way for me to know which SHA1
hashes refer to such submodule objects? I'd like to simply ignore
them.
I presume you are reading "diff-tree --raw" format output. The mode
bits
for submodules (aka gitlinks) are 160000, as opposed to either
100644 or
100755 for regular files and 120000 for symbolic links.
