Update a submodule to the latest commit

Question

I have a project A which is a library and it is used in a project B.

Both projects A and B have a separate repository on github BUT inside B we have a submodule of A

Answer 1

Andy's response worked for me by escaping $path:

git submodule foreach "(git checkout master; git pull; cd ..; git add \$path; git commit -m 'Submodule Sync')"
