#!/bin/bash

#Companion code for the blog https://cloudywindows.com
#call this code direction from the web with:
#bash <(wget -O - https://raw.githubusercontent.com/PowerShell/PowerShell/master/tools/installpsh-debian.sh) ARGUMENTS
#bash <(curl -s https://raw.githubusercontent.com/PowerShell/PowerShell/master/tools/installpsh-debian.sh) <ARGUMENTS>

#Usage - if you do not have the ability to run scripts directly from the web, 
#        pull all files in this repo folder and execute, this script
#        automatically prefers local copies of sub-scripts

#Completely automated install requires a root account or sudo with a password requirement

#Switches
#  -includeide - the script is being run headless, do not perform actions that require response from the console
#  -interactivetests - requires a human user in front of the machine - loads a script into the ide to test with F5 to ensure the IDE can run scripts
#  -skip-sudo-check - skips the check that the user has permission to use sudo.  This is required to run in the VSTS Hosted Linux Preview.

#gitrepo paths are overrideable to run from your own fork or branch for testing or private distribution
