bash function to fetch the latest master on all submodules in parallel, wait until they're all updated, and then delete all pyc files

update-code.sh

function delete-pyc() {
    find . -name '*.pyc' -delete
}
function pull-latest-master() {
    git checkout master; git pull &
    git submodule foreach --recursive 'git checkout master; git pull &'
    until [ -z "$(ps aux | grep '[g]it pull')" ]; do sleep 1; done
}
function update-code() {
    pull-latest-master
    delete-pyc
}

(I have these in my .bash_profile)
