### PREREQUISITES ###
|
||||
# - Install ovftool on the Proxmox host - https://developer.vmware.com/web/tool/ovf/
|
||||
# - Hardcode the variables for your ESXi IP, user, etc.
|
||||
|
||||
# Gets user input, returns the default value if no input was provided.
|
||||
# Doesn't prompt if the variable is already set.
|
||||
# Accepts a validation regex too.
|
||||
#
|
||||
# Usage:
|
||||
#
|
||||
# input BROADCOM_HATE_LEVEL "The amount you hate broadcom" "infinite" "^(none|somewhat|a lot|infinite)$"
