git hash-object path/to/file

• Compute the object ID and store it in the Git database:

git hash-object -w path/to/file

• Compute the object ID specifying the object type:

git hash-object -t blob|commit|tag|tree path/to/file

• Compute the object ID from stdin:

cat path/to/file | git hash-object --stdin
