# wall(1)

write a message to users

## 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 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 messages.

- **-g**

  Send messages to users in this group. This option may be specified multiple times, and any user in any of the specified groups will receive the message.

## SEE ALSO

[mesg(1)](/mesg/1.md), [talk(1)](/talk/1.md), [write(1)](/write/1.md), [shutdown(8)](/shutdown/8.md)

## 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).
