Can I create a new wiki web from command line?
Can I create a new wiki web from command line? E.g.:
twiki create web "NewInfo"
If not, why not?
and preserve the permissions:
sudo cp -Rp data/_default/ data/Newweb
sudo cp -Rp pub/_default/ pub/Newweb
which describes itself as "TWikiShellContrib is a shell that can be use to replace all twiki command line scripts with a single interface. Each command available in the twikishell is also available as a command line option." However, this plugin still needs to be ported.
