How to use the command 'git unpack-file' (with examples)

Git is a widely used version control system, and the ‘git unpack-file’ command is one of the useful commands provided by Git. This command allows users to create a temporary file that holds the contents of a blob specified by its ID. The name of the temporary file is then printed to the console.

Motivation:

The motivation for using this example is when there is a need to access the contents of a specific blob in Git. By using the ‘git unpack-file’ command, a temporary file can be created, making it easier to view and manipulate the blob’s contents.

Explanation:

• git unpack-file: This is the command itself that allows users to unpack a blob and create a temporary file.

The output of this command will be the name of the temporary file that was created to hold the contents of the specified blob. The file name in the example output is ‘unpack-blob-a5144216d64dbce3e3d4d833b0928fa3a79c8f44.tmp’.
