NAME


     wall - write a message to users

 

SYNOPSIS


     wall [file]

 

DESCRIPTION






     Wall displays the contents of file or, by default, its standard 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.

     Reading from a file is refused when the invoker is not superuser and the
     program is suid or sgid.

 

SEE ALSO
