[QnA] Change the permission of viminfo to enable the command histroy of Vim

After upgrading from Ubuntu 8.04 to 10.04, I found the command history of Vim was missing. The reason is simple: in Ubuntu 10.04, the ~/.viminfo file has a 600 permission so only the root can access it.

To get the command history of vim back, you may change the permission from 600 to 666. I don't know whether this change has any side effects, however. At least for only one user using one computer, this is a quick trick. :-)
