WALL(1) BSD General Commands Manual WALL(1) NAME wall -- write a message to users SYNOPSIS wall [-g group] [file] DESCRIPTION The wall utility displays the contents of file or, by default, its stan- dard input, on the terminals of all currently logged in users. Only the super-user can write on the terminals of users who have chosen to deny messages or are using a program which automatically denies mes- sages. -g Send messages to users in this group. This option may be speci- fied multiple times, and any user in any of the specified groups will receive the message. SEE ALSO mesg(1), talk(1), write(1), shutdown(8) HISTORY A wall command appeared in PWB 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 wall has no way of knowing). The wall utility does not recognize multibyte characters. BSD July 17, 2004 BSD
