BIFF(1)                     General Commands Manual                    BIFF(1)



NAME
       biff - give notice of incoming mail messages

SYNOPSIS
       biff [ y|n ]

DESCRIPTION
       biff  turns mail notification on or off for the terminal session.  With
       no arguments, biff displays the current  notification  status  for  the
       terminal.

       If  notification  is  allowed, the terminal rings the bell and displays
       the header and the first few lines of each arriving mail message.  biff
       operates  asynchronously.  For synchronized notices, use the MAIL vari-
       able of sh(1) or the mail variable of csh(1).

       A `biff y' command can be included in your .login or .profile file  for
       execution when you log in.

OPTIONS
       y      Allow mail notification for the terminal.

       n      Disable notification for the terminal.

FILES
       .login
       .profile

BUGS
       You must have ownership the terminal to  change  its  mail-notification
       status with biff, but windows running under sunview(1) are owned by the
       super-user.  If you enable mail notification for the  workstation  con-
       sole  (in  your  .login  or  .profile file), incoming mail notices also
       appear on console windows running under sunview(1).   See  shelltool(1)
       or cmdtool(1) for details.
