Add entry into httpd.conf

nebola has asked for the wisdom of the Perl Monks concerning the following question:

Greetings wise Monks,

I've just started learning perl. And I have this assignment, to do. Taking a look at my httpd.conf:

<VirtualHost 64.194.130.12>
        ServerAdmin admin@foo.org
        DocumentRoot /home/eric
        ServerName eric.foo.org
        ErrorLog logs/eric.foo.org-error_log
        CustomLog logs/eric.foo.org-access_log common
ScriptAlias /cgi-bin/ /home/eric/cgi-bin/
</VirtualHost>

<VirtualHost 64.194.130.12>
        ServerAdmin admin@woo.org
        DocumentRoot /home/michael
        ServerName michael.woo.org
        ErrorLog logs/michael.woo.org-error_log
        CustomLog logs/michael.woo.org-access_log common
ScriptAlias /cgi-bin/ /home/michael/cgi-bin/
</VirtualHost>

Some other configuration options here, not related to VirtualHost entries...

------

I want to make a script(ran as root) that:

1. Asks for inputs servername and documentroot.
2. From these open httpd.conf file, add in an entry(a line) for cgi-bin2 just before the closing </VirtualHost> for that particular VirtualHost entry only. eg. Michael but not Eric.
3. Make the directory cgi-bin2 in documentroot.

<VirtualHost 64.194.130.12>
        ServerAdmin admin@woo.org
        DocumentRoot /home/michael
        ServerName michael.woo.org
        ErrorLog logs/michael.woo.org-error_log
        CustomLog logs/michael.woo.org-access_log common
ScriptAlias /cgi-bin/ /home/michael/cgi-bin/
<<---- (add ScriptAlias /cgi-bin2/ /home/michael/cgi-bin2/)
</VirtualHost>

Any ideas and pointers would be greatly appreciated. Thanks in advance.

If you'd add `mod_perl` to your configuration, you can generate your config files during boot time using Perl code, programmatically. There's an example of driving a configuration from a DBI database in the mod_perl cookbook. -- Randal L. Schwartz, Perl hacker	[reply]

This is a variant of a FAQ ("How do I insert a line into a file" ?). The first part of your task is to figure out what pattern is going to be in the line you want to insert stuff after. Presumably the 'magic' line that tells you you're in the configuration for the right virtual host is the `ServerName bar.woo.org` [download] One way of tackling your problem: open a file for writing, and open your httpd.conf file for reading. Set a flag when you find that magic line; simply print the line you read in from your old file to the new file, UNLESS the flag is set AND you've found the terminating line `</VirtualHost>`; all you need to do when that condition is met is print the new `ScriptAlias` line to the new file, and go on as before. Skeleton code (just to illustrate the logic): `# get name of person, put it in $name my $flag =0; while (<OLD>) { # set the flag $flag =1 if /[^#]ServerName $name.woo.org/; #now check to see if we've found the ending line if ($flag && #</VirtualHost>#) { print NEW "ScriptAlias blah blah\n"; $flag =0; } print NEW; # implicit $_ }` [download] HTH Philosophy can be made out of anything.
