[dokuwiki] Re: How to move media and preserve the links?

Hello,
i've got the same problem. Reorganizing the wiki's namespaces,pages and mediafiles is a common task for every wikiadmin 
and should therefore be an integrated part of dokuwiki.
I do the job using a bash script (see below), but its really a hack.
One should reindex the wiki after doing that, because the script works on the filesystem level only.
One thing so solve is to handle relative namespaces [[.:----]] on moving.
