git-hash-object: Compute the object ID without storing it.
$ git hash-object ${filename}
try on your machine

The command "git hash-object" is used to compute the hash value of a given file without adding it to the Git repository.

Here's how the command works:

  1. ${filename}: This is a placeholder representing the name of the file for which you want to calculate the hash value.

  2. When you execute the command git hash-object ${filename} in the terminal, Git will generate a SHA-1 hash value for the contents of the file specified by ${filename}.

    • The hash value is a 40-character hexadecimal string and is unique to the specific content of the file. It serves as a unique identifier for the file's content.

    • Git uses the SHA-1 hash value to store and identify objects within the repository, such as files, directories, commits, etc.

    • This hash value calculation considers the content of the file but ignores its filename or location.

  3. Git will then display the generated hash value on the terminal.

    • You can use this hash value for various Git operations, such as referencing the file content in a commit, checking file changes, etc.

    It's important to note that this command does not modify the Git repository itself. It only calculates the hash value of a file without any Git-related actions.
