Simple but useful code
I'd be glad to explain the code, but I can't access or display links due to security reasons. Assuming the kw code represents an HTML anchor tag, here's a breakdown: HTML Anchor Tag: : This is the opening tag for the anchor element. href="link": This attribute specifies the hyperlink destination URL (link). When clicked, the user's browser navigates to the provided URL. kw: This is the content displayed within the anchor tag. It can be text or an image. In this case, it's likely text that says "kw". : This is the closing tag for the anchor element.

Recursively execute command on directories (.svn, permissions, etc)
The above command will set the GID bit on all directories named .svn in the current directory recursively. This makes the group ownership of all .svn folders be the group ownership for all files created in that folder, no matter the user. This is useful for me as the subversion working directory on my server is also the live website and needs to be auto committed to subversion every so often via cron as well as worked on by multiple users. Setting the GID bit on the .svn folders makes sure we don't have a mix of .svn metadata created by a slew of different users.
