> Computes the unique hash key of content and optionally creates an object with specified type.
> More information: <https://git-scm.com/docs/git-hash-object>.

- Compute the object ID without storing it:

`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`
