git rev-parse master^{commit} 是什么意思？！

Question

git rev-parse refs/remotes/origin/master^{commit}

这里的 ^{master} 是啥意思？！在reset的时候^可是指代的上一版本啊？！

Answer 1

If you want to make sure that the output actually names an object in your object database and/or can be used as a specific type of object you require, you can add the ^{type} peeling operator to the parameter. For example, git rev-parse "$VAR^{commit}" will make sure $VAR names an existing object that is a commit-ish (i.e. a commit, or an annotated tag that points at a commit). To make sure that $VAR names an existing object of any type, git rev-parse "$VAR^{object}" can be used.

在这里^{type}是指定类型的意思
