Adding multiple lines into file

[c0mrade]

I'm trying to figure out how to write multiple lines at the end of a file.. reason why I need this is I'm hosting couple of website on my machine and it gets boring to write every time same lines

<VirtualHost yourhostname:80>
    ServerAdmin you@your-domain.com
    ServerName your_ip_address
    DocumentRoot /www
    ErrorLog logs/error_log
    CustomLog logs/access_log combined
</VirtualHost>

Is there a way to write a shell script that will insert these lines at the end of the file... any hints indications how to do it ? Thank you in advance ..

Save the above lines in a file, say AppendedLines, then do:

cat AppendedLines >> VirtualHostFile

$ sh  update_apache hercules.utp.xnet j65nko pietje_puk.nl 81.00.00.01

$ cat httpd.conf                                                     
<VirtualHost hercules.utp.xnet:80>
    ServerAdmin j65nko@pietje_puk.nl
    ServerName 81.00.00.01
    DocumentRoot /www

    CustomLog logs/access_log combined
</VirtualHost>

Here's an idea:
Add "Include etc/apache/virtualhosts" to httpd.conf
and then create a config file (containing only <VirtualHost..>...</VirtualHost>) for each virtualhost in virtualhosts/ directory.
