Delete .svn folders recursively using command line

Khalil Majdalawi — Mon, 05 Oct 2009 08:42:27 +0000

some times i work on small projects with friends and we use Subversion to track and store code changes, collaborate, and share project files so once we finish we usually upload it somewhere by copying the whole project folder so i face that subversion makes folder inside each folder in the project called “.svn” and that take time to remove manually and unnecessary size to upload
so i run a command inside the project folder to remove that folders recursively before upload.

Run this:

find . -name .svn -exec rm -rf {} \;

its very simple SEO trick to avoid duplicate content on Google search engine and increase your rank , you have to chose which one suit you www or non-www

first you have to enable “rewrite mod” which is apache server feature click here

then use the following lines in your .htaccess file
to remove WWW

RewriteEngine On
RewriteCond %{HTTP_HOST} ^www.example.com$ [NC]
RewriteRule ^(.*)$ http://example.com/$1 [R=301,L]

to force WWW

RewriteEngine on
RewriteCond %{HTTP_HOST} ^example.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]

Please, note that the .htaccess should be located in the web site main folder.
