Question

I have moved a website to another subdomain and some of the hard coded link are causing problem.

Original website

<pre>
www.example.com
</pre>

New Website

<pre>
subdomain.example.com
</pre>

Some of the php code in the files reside in the www directory has http://www.example.com in them. How can find the “www.example.com” in the *.php pages and replace them with “subdomain.example.com”. There are in recursive directories as well so I would like to change them.

Answer 1

You can do this easily from the command line via

find /path/to/files -name '*.php' | xargs sed -i -e s/www.example.com/subdomain.example.com/g

You can adjust the file set by sending extra parameters to find and you can do a more sophisticated replacement by adjusting the expression given to sed (for example, to ensure the matched pattern is a whole word).
