GIT-HASH-OBJECT(1) Git Manual GIT-HASH-OBJECT(1)
git-hash-object - Compute object ID and optionally creates a blob from
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. This is used by git
cvsimport to update the index without modifying files in the work tree.
When <type> is not specified, it defaults to "blob".
Specify the type (default: "blob").
Actually write the object into the object database.
Read the object from standard input instead of from a file.
Read file names from the standard input, one per line, instead of
from the command-line.
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.
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.
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.
