I have a ./gitmodules file which looks like this:
[submodule "external/mpifx/origin"]
path = external/mpifx/origin
url = https://github.com/dftbplus/mpifx.git
[submodule "external/scalapackfx/origin"]
path = external/scalapackfx/origin
url = https://github.com/dftbplus/scalapackfx.git
How can I pull all of this submodules from the command line?
