Internet Tools Ah, the Internet, the vast meta-network that is probably the reason you're learning Unix. Internet commands are straightforward, but can contain subtle nuances of their own. This program allows you to connect to other computers on the 'net and copy files to and from them. You normally need to have an account and password on the remote computer to get and place files. The Usenet contains a wealth of ongoing discussions on every topic imaginable.
Gopher is one of a new breed of tools that are making the Internet easier to use.
Mail or elm or others - these programs let you read and send electronic mail. Mail is a very simple program that is available on every Unix system. The elm program will only be available if your system administrator specifically put it there. If it is, you'll find it much easier to use electronic mail than with Mail. Other fine mail programs are available also.
