Complete Git Guide: Understand and Master Git and GitHub - Why Git Blobs do not Store File Names

The video tutorial explains the concept of Git blobs, highlighting that blobs do not store file names but are named based on a SHA-1 hash of their content. It discusses how Git stores the size and type of each object directly within the blob. The tutorial also compares SHA-1 hashes generated by different utilities, explaining why they differ. The session concludes with a brief preview of the next lecture.

What is the basis for the file name of a Git blob?

• The file's size

• A SHA-1 hash of the file contents

• The original file name

• The file's creation date

Which of the following information can be retrieved from a Git blob?

• File permissions

• Size and type of the object

• File path

• Original file name

Why can't the original file name be retrieved from a Git blob?

• It is stored in a separate file

• It is not stored in the blob

• It is overwritten by the hash

• It is encrypted

What additional information does Git include in the SHA-1 hash generation process?

• File permissions

• File path

• Size and type of the object

• Timestamp of creation

Why might SHA-1 hashes differ when generated by different utilities?

• The utilities use different hash lengths

• The file contents are altered

• Git includes additional information like size and type

• Different utilities use different algorithms
