如何使用Shell脚本使'index.php'优先于'index.html'

Question

I'm automating a server setup and to install PHP I need to add index.php to /etc/apache2/mods-enabled/dir.conf.

The target content of the file looks like this:

<IfModule mod_dir.c>

          DirectoryIndex index.html index.cgi index.pl index.php index.xhtml index.htm

</IfModule>

I need to add index.php before index.html.

It should end up looking like this

<IfModule mod_dir.c>

          DirectoryIndex index.php index.html index.cgi index.pl index.xhtml index.htm

</IfModule>

How do I do this with a shell script?

Answer 1

All you're doing is making index.php higher priority than index.html. It's an odd thing to need to do, and probably better done in .htaccess or something. However, if you really want to make the change in the config file directly you can use sed. In this case something like the following:

cd /etc/apache2/mods-enabled
sed -e 's/\s*DirectoryIndex.*$/\tDirectoryIndex index\.php <...> index\.htm/' \
    dir.conf > dir.conf.tmp && mv dir.conf.tmp dir.conf

You need to be sure that 'DirectoryIndex' only appears once though, and fill in <...> with the rest of the line (escaping dots: 'index.pl' -> 'index\.pl').
