The command "git stash pop" is used to retrieve and apply the most recent stash that was created in your Git repository. It's typically used when you want to apply the changes that were stashed and remove them from the stash list.
The "${optional_stash_name}" part in the command is an optional parameter that allows you to specify a specific stash to apply instead of using the most recent one. If you don't provide a stash name, it will apply the most recent stash by default.
Here's how the command works:
- It retrieves the most recently created stash (or the one specified by "${optional_stash_name}") from the stash list.
- It re-applies the changes that were stashed back to your working tree and index, effectively reapplying the changes made to the files.
- It removes the stash from the stash list, as it's no longer needed since the changes have been restored.
Note that if conflicts occur during the pop operation (for example, if the same lines were modified both in the stash and in your current branch), Git will notify you about the conflicts and you'll need to resolve them manually.
Using "git stash pop" instead of "git stash apply" is convenient when you no longer need to retain the stashed changes in the stash list, as it automatically removes the stash after applying the changes.
