Download file from cloud.mail.ru from linux console with bash script

dl-cloud-mail-ru.sh

#!/usr/bin/env bash

# IMPORTANT: mail.ru sometimes changes internals, not too much, but script must be changed. 
#
# If this script does not work:
#   - see forks, may be there is a fix already,
#   - if not, please post patch in comments or create a working fork of this gist.
# Thank you!

# ВАЖНО. mail.ru время от времени меняет внутрянку, не очень сильно, но требуется адаптация скрипта.
# Если скрипт не работает, просьба разместить патч в комментариях или сделать работающий форк.

# 2021-05-26 updated: don't make an API call
# 2021-05-26 updated: mail.ru doesn't require token now
# 2018-06-18 updated: mail.ru changed internals
# 2017-09-22 original idea: https://novall.net/itnews/bash-skript-dlya-skachivaniya-fajlov-s-mail-ru-cherez-konsol-linux.html
