git の submodule を最新に更新する

手順

git submodule foreach git stash
git submodule foreach git checkout master
git submodule foreach git pull origin master

実行例

1. 念のため、変更を退避します。

   C:\gitwork\GitHub\googletest-sample-cmake>git submodule foreach git stash
   Entering 'googletest'
   No local changes to save
   

2. master をチェックアウトします。

   C:\gitwork\GitHub\googletest-sample-cmake>git submodule foreach git checkout master
   Entering 'googletest'
   Already on 'master'
   Your branch is up to date with 'origin/master'.
   

3. 最新の修正を取り込みます。

   C:\gitwork\GitHub\googletest-sample-cmake>git submodule foreach git pull
   Entering 'googletest'
