Pull git submodules in parallel using GNU parallel

Make sure to run this command in your git toplevel directory. Modify `-j4` as you like. You can also run any arbitrary command beside `git pull` in parallel on all of your git submodules.

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'

git submodule foreach git pull \&

Alternatively, using xargs and submodule update:

git submodule status | awk '{print $2}' | xargs -P5 -n1 git submodule update --init
