git hash-object

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
