What Others Think

Personally, I'd tidy the syntax a little (make the command a bit shorter, too): git submodule status | awk '{print $2}' | parallel -j4 'cd {}; pwd; git pull'

I think this is often good enough: git submodule foreach git pull \&

Alternatively, using xargs and submodule update: git submodule status | awk '{print $2}' | xargs -P5 -n1 git submodule update --init
