Bulk adding of domains in ispmanager 6

To bulk add domains in ispmanager 6, you can use this script. The script allows you to add domains via the CLI in a semi-automated mode.

To bulk add domains, follow these steps:

1. Connect to the server via SSH as the root user;
2. Download and place the script in any accessible directory, such as /root;
3. Make the script executable by running chmod +x add_domains_ispmgr.sh;
4. Prepare and place a text file named domains.txt next to it, containing the names of the desired domains (one line per domain);
5. Run the script with the command ./sh add_domains_ispmgr.sh and go through all the steps for each domain:
   1. Enter the username of the user the domain will be added to;
   2. Select a handler;
   3. Select the handler mode;
   4. Determine whether to add a Let's Encrypt SSL certificate.
