FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

write - send a message to another user

 

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 mes‐
      sage 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 termi‐
      nal.  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 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 is the
      other person’s turn to talk.  The string ‘oo’ means that the person
      believes the conversation to be over.
      mesg(1), talk(1), wall(1), who(1)
 

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).
 
      The write utility does not recognize multibyte characters.

Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
