wall(1M) (MLX Addendum)            (MLX)            wall(1M) (MLX Addendum)

NAME
     wall - write to all users (MLX addendum)

SYNOPSIS
     /usr/sbin/wall [-g group]

DESCRIPTION
     (International Functions)

     wall can send characters from supplementary code set.

     Supplementary characters from code sets which do not match between the
     sender and receiver are ignored.

     Options:

     -ggroup
          Send only to members of the group group.

NOTES
     Messages exceeding a total length of 3000 bytes are silently trun-
     cated.

     To determine printability of a supplementary character, wall requires
     the width of that character's code set for the sender (determined by
     getwidth() from the LC_CTYPE table for the current locale) to match
     the width of the corresponding code set according to the line discip-
     line of the receiving terminal.
