Set proxy variables from bash when you don't want to have the password hardcoded, or in a command history. Works in windows with git bash

set proxy

#!/bin/bash

[[ $_ != $0 ]] && echo "Write your password:" || 
  echo "You need to call this from the source command: source $(basename $0)"

PROTOCOL=http
USERNAME=myuser
HOST=proxy.bigevilcorporation.com
PORT=8009
  
read -s PASS
export http_proxy=$PROTOCOL://$USERNAME:$PASS@$HOST:$PORT
export https_proxy=$http_proxy
export HTTP_PROXY=$http_proxy
export HTTPS_PROXY=$http_proxy
