Editing files online

Downloading files, editing, then uploading the files is not the fastest way to

make simple changes. The experienced Virtual Server Administrator uses

an online editor to make changes to files while in a Telnet or SSH session.

Below are a couple of the online editors available.

Using vi to edit

Vi is a common UNIX editor. The commands in vi are a bit difficult to get

used to at first. When you get used to the commands it is a powerful tool.

Here are some of the basic commands.
