# This script does exactly 3 things for 1 good reason:
|
|
#
|
|
# What this does:
|
|
#
|
|
# 1. Detects either curl or wget and wraps them in helpers
|
|
# 2. Exports the helpers for the real installer
|
|
# 3. Downloads and runs the real installer
|
|
#
|
|
# Why
|
|
#
|
|
# 1. 'curl <smth> | bash -- some args here` breaks interactive input
|
|
# See https://stackoverflow.com/questions/16854041/bash-read-is-being-skipped-when-run-from-curl-pipe
|
|
#
|
|
# 2. It also has practical risks of running a partially downloaded script, which could be dangeresque
|
