“git clone -b name url”与“git clone url --branch name”是否相同？

Question

我想知道这两个git命令是否完全相同？

git clone git://git.yoctoproject.org/poky --branch daisy

git clone -b daisy git://git.yoctoproject.org/poky.git

Answer 1

根据git手册页，theese命令是相同的：

$ git help clone
 ....
 --branch <name>, -b <name>
 Instead of pointing the newly created HEAD to the branch pointed to by the cloned repository’s HEAD, point to <name> branch instead. In a non-bare
 repository, this is the branch that will be checked out.  --branch can also take tags and detaches the HEAD at that commit in the resulting
repository.
 ....

正如您所看到的，-b和--branch只是同义词。缺少扩展.git（在第一种情况下）是自动确定的（考虑到协议git://）并且参数的顺序无关紧要。
