sir, would you please elaborate a little more how to use it simply in terminal. I removed # sign from first line and ran command by name starting ./ but not working. followings are the errors
1- ./passwords_downloader: 1: !/bin/bash: not found
2- ./passwords_downloader: 1: Bad substitution
3- ./passwords_downloader: 14: function: not found
.. more over I want to download all 10000 of avaiable, but you specify limit upto 100. can i change it to 10000?.

Thank
