Using Axel to Download Password-Protected Files on Linux

One way to download files on Linux through the terminal is by using Axel. The problem arises when the file you want to download requires a username and password. Here’s how to do it:

1. Use the following command:

   axel -a -n 2 https://username:password@url_file_to_download
   

If the password contains special characters, enclose the password in quotes, as shown in the example below:

   axel -a -n 2 https://username:'p@ssw0rdun!qu3'@url_file_to_download
