Apply stash意思

"Apply stash" is a term commonly used in version control systems, particularly in Git, which is a distributed version control system widely used in software development. The term "stash" refers to a temporary storage area for changes that you want to keep but not commit to the repository yet.

Here's what "apply stash" means in the context of Git:

  1. Stashing Changes: Before you can apply a stash, you need to stash your changes. Stashing is like a quick way to save your changes without committing them. It's useful when you want to switch branches or work on something else without committing your current changes. You can stash your changes by running git stash.

  2. Applying a Stash: After you've stashed your changes, you can apply them back to your working directory. To apply a stash, you can use the git stash apply command. This will take the most recent stash and apply it to your working directory, meaning the changes that were previously stashed will be back in your files.

  3. Listing Stashes: If you have multiple stashes, you can list them using git stash list. This will show you a list of stashes, each identified by a stash number and a description (if provided).

  4. Picking a Specific Stash: If you have multiple stashes and you want to apply a specific one, you can use the stash number. For example, git stash apply stash@{1} will apply the second most recent stash (counting from the top, with the most recent being stash@{0}).

  5. Discarding a Stash: If you no longer need a stash, you can discard it using git stash drop. You can specify a stash number to drop a specific stash, or you can use git stash drop --all to drop all stashes.

It's important to note that when you apply a stash, it will overwrite any changes in your working directory that are not part of the stash. If you have made new changes after stashing, you may need to resolve any conflicts that arise.

In summary, "apply stash" means to take the changes that were previously stashed and bring them back into your working directory, effectively un-stashing them.
