a simple script I use for updating my Homebrew, composer, pip, npm, and gem packages

update_toolset.sh

set -e
set -x

sudo aptitude update 
sudo aptitude upgrade -y

for package in $(npm -g outdated --parseable --depth=0 | cut -d: -f2)

do
  sudo npm -g install "$package"
done
     
sudo composer self-update
gem update
pip freeze | grep -v '^\-e' | cut -d = -f 1  | xargs pip install -U
