git-hash-object - Compute object ID and optionally creates a blob
from a file
git hash-object [-t <type>] [-w] [--path=<file> | --no-filters]
[--stdin [--literally]] [--] <file>...
git hash-object [-t <type>] [-w] --stdin-paths [--no-filters]
Computes the object ID value for an object with specified type
with the contents of the named file (which can be outside of the work tree),
and optionally writes the resulting object into the object database. Reports
its object ID to its standard output. When <type> is not specified, it
defaults to "blob".
-t <type>
Specify the type (default: "blob").
-w
Actually write the object into the object database.
--stdin
Read the object from standard input instead of from a
file.
--stdin-paths
Read file names from the standard input, one per line,
instead of from the command-line.
--path
Hash object as it were located at the given path. The
location of file does not directly influence on the hash value, but path is
used to determine what Git filters should be applied to the object before it
can be placed to the object database, and, as result of applying filters, the
actual blob put into the object database may differ from the given file. This
option is mainly useful for hashing temporary files located outside of the
working directory or files read from stdin.
--no-filters
Hash the contents as is, ignoring any input filter that
would have been chosen by the attributes mechanism, including the end-of-line
conversion. If the file is read from standard input then this is always
implied, unless the --path option is given.
--literally
Allow --stdin to hash any garbage into a loose
object which might not otherwise pass standard object parsing or git-fsck
checks. Useful for stress-testing Git itself or reproducing characteristics of
corrupt or bogus objects encountered in the wild.
