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
