Doing some work on your web site but you don't want other people to see what you're doing. Give them a redirect (like the flickr massage screen).
You need to use your own ip of course.

After unzipping, taring or whatever archive you used copy thepatch over the old files, replacing them.

Copy the files in your newly extracted directory (pmwik-new/wordpress-patch) over the files of your existing software installation. For example, if your existing PmWiki/Wordpress installation is in a directory called pmwiki/wordpress, then one way to copy the new files over the existing ones is to enter the command:

cp -a pmwiki-new/. pmwiki

Note that BSD systems will not have the -a option as a command-line argument for cp, but that's okay, since it's just shorthand for cp -dpR, so use that instead of -a.

On (some) FreeBSD servers and Mac OS X systems you need to use

cp -Rpv pmwiki-new/. pmwiki 

This works well on TxD shared hosting.

I found it really difficult to get svn via svn+ssh geting to work because I made two erorrs:
I used not my main user. However, only the main user can get shell access necessary for svn via ssh.
I used a wrong path.

In order to get things going set up subversion following the usual directives in the knowledge base and then access your repository like this:
(OS X terminal here)

% svn co svn+ssh://mainuser@yourdomain.tld/home/mainuser/svn/repositoryname/

This should do the trick.

Remember not to use ssh and http(s) at the same time. It's either or.

In your .htaccess file (maybe only in a specific folder) add this line to parse a .htm as a php file. This works on TxD accounts.

AddType application/x-httpd-php .htm .php
