git clone時にcheckoutしないようにする

git cloneのno-checkoutオプション

man git-clone

       --no-checkout, -n
           No checkout of HEAD is performed after the clone is complete.

-nオプションを使うとclone後にcheckoutしなくなります。
例えば、こんなふうに。

Yamauchi:test yamauchi$ git clone -n https://github.com/torvalds/linux.git

clone後、branchやtagを切り替えることが明確に分かる場合は、ちょっとだけ時間短縮に・・・。
