UNIX for Dummies Questions & Answers

There is file named .htaccess. It is located in many directories on my web server. Instead of manually editing each file to add specific text, i thought there is possibly a command which will allow me to do that.

What i need to be done exactly?

In all .htaccess files i need to add/append the following text:

Code:

RewriteRule . /index.php [L]

The above text needs to be added/appended to this code:

Code:

RewriteEngine On

Important! The text must be added below of the code above. I mean it must start with new line and it must be added before the next code.

Here is how it all must look in the end:

Code:

RewriteEngine On
RewriteRule . /index.php [L] <<< This text must be added in between codes
RewriteCond %{REQUEST_FILENAME}

Was i clear on that? I will really appreciate your help people!
Thanks.

It should be simple with the combination find & sed as.,

Code:

find . -iname 'htaccess' -exec sed -i 's@RewriteEngine On@RewriteEngine On\nRewriteRule . /index.php [L]@' {} \;

Before running the above command,

Code:

$ cat 1/htaccess 
RewriteEngine On
testing line2
$ cat 2/htaccess 
testing line1
RewriteEngine On    
this is line3

After running,

Code:

$ cat 1/htaccess 
RewriteEngine On
RewriteRule . /index.php [L]
testing line2
$ cat 2/htaccess 
testing line1
RewriteEngine On
RewriteRule . /index.php [L]
this is line3

Hope your sed allows inplace editing, else try using perl.
