NAME

git-hash-object - Compute object ID and optionally create an object
from a file

SYNOPSIS

git hash-object [-t <type>] [-w] [--path=<file> | --no-filters]
[--stdin [--literally]] [--] <file>...
git hash-object [-t <type>] [-w] --stdin-paths [--no-filters]

DESCRIPTION

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".

OPTIONS

-t <type>
Specify the type of object to be created (default: "blob").
Possible values are commit, tree, blob, and tag.

-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 if it were located at the given path. The location
of the file does not directly influence the hash value, but the
path is used to determine which Git filters should be applied to
the object before it can be placed in the object database. As a
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.
