WRITE(1)                   Linux Programmer's Manual                  WRITE(1)



NAME
       write - send a message to another user

SYNOPSIS
       write user [ttyname]

DESCRIPTION
       Write 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  indi-
       cating that the conversation is over.

       You  can  prevent  people  (other than the super-user) from writing to you with the mesg(1) command.  Some com-
       mands, for example nroff(1) and pr(1), may disallow writing automatically, so that your output isn't  overwrit-
       ten.

       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 terminal 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's  the  other  person's turn to talk.  The string 'oo' means that the person
       believes the conversation to be over.
