Remove files that are not in subversion
One of the great features of version control is that I can easily revert back to a known good state. I can do this in Subversion with the following command:
% svn revert -R .
However, if I have new files that are not in Subversion, this command will not delete them. Here is a fun ruby one liner to remove those files:
svn st | ruby -ne 'File.delete($_[1..-1].strip) if $_.match(/^\?/)'
This command loops over svn status and deletes all files from lines that start with ?.
