While I've looked at:

http://rushi.wordpress.com/2008/08/05/find-replace-across-multiple-files-in-linux/

and

http://www.liamdelahunty.com/tips/linux_search_and_replace_multiple_files.php

when I try to use them, neither accomplishes what I am looking for.  basically I want to do site-wide replace of a multiple line javascript by using a command line find/replace in linux.


in terms of modifying perl -pi -w -e 's/\.\.\/includes\/style\.css/admin\.css/g;' *.php

I am not sure how to change it to handle (a) multiple lines and (b) multiple directories.

here's what I want to find:

<!-- Start Quantcast tag -->
<script type="text/javascript">
if(window.location.protocol != 'https:') {
    document.write('<script src="http://edge.quantserve.com/quant.js" type="text/javascript"><\/script>');
    document.write('<script type="text/javascript">_qacct="p-XXXXXXXXXXXXXXXX-";quantserve();<\/script>');
}
</script>
<!-- End Quantcast tag -->

and replace it with:

<script type="text/javascript">
_qoptions={
qacct:"p-XXXXXXXXXX-"
};
</script>
<script type="text/javascript" src="//secure.quantserve.com/quant.js"></script>
<noscript>
<img src="//secure.quantserve.com/pixel/p-XXXXXXXXXXX-.gif" style="display: none;" border="0" height="1" width="1" alt="Quantcast"/>
</noscript>

any suggestions?

assuming you have a perl script which makes your changes for one file:

find /path/to/dir/where/to/start/ -type f -name \*.php -exec your-script.pl -pi {} \;

# to be improved in many ways ...

definitely a step in the right direction...

I don't have the multi-line regex as of yet, so i'm going to leave it open for a day or two to see if anyone appears with one.

if not, i'll give you the points and ask that in the perl area.
