I have just watched users get farther and farther from what the computer is actually doing. Layer after layer is being applied to the GUI each one more user friendly but also less capable of knowing what is wrong with it when something does go wrong.
I guess I should have said I was in IT support...
I have just noticed a trend of an unfortunate number of people who are "good with computers" but not familiar with anything going on behind the mouse and desktop. (To be certain that kind of person fills a niche in the technology field, but when the computer crashes and you have to boot to a command line they get lost.

write
WRITE(1) BSD General Commands Manual WRITE(1)
NAME
write -- send a message to another user
SYNOPSIS
write user [tty]
DESCRIPTION
The write utility allows you to communicate with other users, by copying lines from your terminal to theirs.
When you run the write command, the user you are writing to gets a message of the form:
Message from yourname@yourhost on yourtty at hh:mm ...
Any further lines you enter will be copied to the specified user's terminal. If the other user wants to reply, they must run write as well.
When you are done, type an end-of-file or interrupt character. The other user will see the message 'EOF' indicating that the conversation is
over.
You can prevent people (other than the super-user) from writing to you with the mesg(1) command.
If the user you want to write to is logged in on more than one terminal, you can specify which terminal to write to by specifying the termi-
nal name as the second operand to the write command. Alternatively, you can let write select one of the terminals - it will pick the one
with the shortest idle time. This is so that if the user is logged in at work and also dialed up from home, the message will go to the right
place.
The traditional protocol for writing to someone is that the string '-o', either at the end of a line or on a line by itself, means that it is
the other person's turn to talk. The string 'oo' means that the person believes the conversation to be over.

HISTORY
A write command appeared in Version 1 AT&T UNIX.
BUGS
The sender's LC_CTYPE setting is used to determine which characters are safe to write to a terminal, not the receiver's (which write has no
way of knowing).
