Hi,

vim /etc/hosts will do what you want. As for a doc, I don't know of one: try Googling for something like "unix file system" and "unix file system layout", that returned these two promising documents, but I don't know if they're at the right level for you:

• http://heather.cs.ucdavis.edu/~matlo.../FileSyst.html
• http://www.unixgeeks.org/security/ne...nix/files.html

HTH,

Andrew
