With git, I've used "references" with at sign and curly braces, like @{UPSTREAM} or @{PUSH}, but I can't find them in https://git-scm.com/docs.

Where can I find an exhaustive list of them and their descriptions?

CodePudding user response：

man gitrevisions (that page on git-scm.com/docs) simply refers to it as "the @ construct". It's one of several constructs (collectively referred to, I think, as extended SHA syntax) used to construct "names" that resolve to one or more SHA hashes.
