• 6. Talking to others

    Already in the early 60s with the advent of time-sharing systems people passed messages through shared files. It was easy to implement because all were in the same computer - the recipient's username was also his mailbox. Over time, a middle-man, an agent, became necessary to keep order. The electronic mail was born. Then it was extended to work across computers, and above all across incompatible computers, a complex web of gateways and routing systems were developed - each having its own formats for the mail address. The universal format today, user@domain, was created in 1971.

    Applications like short messages and chat are very old ideas too, which went through similar developments.

    In this unit you will get to know those original tools which were for communicating with the others in the same machine, and above all, how the e-mail worked and still does - all in the command line.

    The commands in this unit: finger | id | last | mail | mesg | talk | what | who | whoami | write
