In Git, the "@" symbol is used to distinguish between different parts of a Git command.

For example, in the "git log" command, the "@" symbol can be used to refer to different versions of a file, changes, or commits.

For instance, if you use "HEAD@" in a Git command, it refers to the latest commit on the current branch you are on.

Similarly, if you use "origin@{1}" in a Git command, it refers to a specific remote ref, such as the previous position of a branch before it was updated.

Overall, the "@" symbol in Git commands is used to reference specific objects or versions in the Git repository.
