Install and Update all dependencies on a Cloud9 workspace to build a Static website with Hugo and host on Google App Engine

update_workspace.sh

#!/bin/bash

# This script will update a new workspace created on Cloud9 IDE with the latest packages. 
# In order to use it, create a update_workspace.sh file in your C9 Workspace and then make it executable using the command
# `touch update_workspace.sh && chmod +x update_workspace.sh`. 
# Now you can open the updata_workspace.sh file and copy/paste this full script, save and close. 
# Run the command `./update_workspace.sh` to execute the script.
#
# Alternatively you can use this command to download and make this script executable from github
# wget -O update_workspace.sh  https://gist.githubusercontent.com/aubort/836888f8aaeeeff75024c87e9c9199f0/raw && chmod +x update_workspace.sh
#
# If you use the following command, it will automatically run the script after having created it
# wget -O update_workspace.sh  https://gist.githubusercontent.com/aubort/836888f8aaeeeff75024c87e9c9199f0/raw && chmod +x update_workspace.sh && ./update_workspace.sh
