git-rev-parse: Get the commit hash of a branch.
$ git rev-parse ${branch_name}
try on your machine
This command git rev-parse ${branch_name} is used to determine the commit SHA (short for Secure Hash Algorithm) of the specified branch in a Git repository.
Here's a breakdown of the different components:
git: Refers to the Git version control system.rev-parse: Is a Git command that can be used for various purposes, but in this case, it is used to retrieve the commit SHA.${branch_name}: Represents a placeholder for the actual name of the branch you want to determine the commit SHA for. For example, if you have a branch called "feature-branch", you would replace${branch_name}withfeature-branch.
When you execute this command in your Git repository, Git will search for the specified branch (${branch_name}) and return the commit SHA associated with it. The commit SHA is a unique identifier for each commit in Git and is usually a hexadecimal string.
Knowing the commit SHA is useful for various Git operations, such as examining the commit history, comparing branches, creating branches based on specific commits, reverting changes, and more.
