     wall — write a message to users

     wall [-n] [-t TIMEOUT] [file]

     Wall displays the contents of file or, by default, its standard input, on the ter‐
     minals of all currently logged in users. The command will cut over 79 character
     long lines to new lines. Short lines are white space padded to have 79 characters.
     The command will always put carriage return and new line at the end of each line.

     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 messages.

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