Bash script to run some common updates/commands I use

run-updates.sh

#!/bin/bash

# PREREQUISITES:
# - Homebrew
# - Zsh
# - oh-my-zsh
# - Node.js with the following global packages installed:
#   - npm-check-updates
#   - n
# - Docker

# homebrew housekeeping
brew cleanup && brew doctor
# update/upgrade homebrew packages
brew update && brew upgrade

# update oh-my-zsh
"$ZSH/tools/upgrade.sh"

# make sure LTS version of Node.js is installed (and npm is up to date)
n lts && npm i --location=global npm corepack
# make sure latest version of Node.js is installed (and npm is up to date)
n latest && npm i --location=global npm corepack

# run npm-check-updates on global npm packages
command=$(ncu -g | tail -n 2)
# if there are any updates, upgrade those global packages
update_string='npm -g install'
if [[ "$command" == *"$update_string"* ]]; then
  # echo "$command"
  eval "$command"
fi

# update all docker images
for image in $(docker images --format "{{.Repository}}:{{.Tag}}"); do docker pull "$image"; done
# remove any stale docker images
docker rmi -f "$(docker images -f dangling=true -q)"
