WALL(1) Linux User's Manual WALL(1)NAME
wall -- send a message to everybody's terminal.
wall [-n] [ message ]
Wall sends a message to everybody logged in with their mesg(1) permission set to yes. The message can be given as an argument to wall, or
it can be sent to wall's standard input. When using the standard input from a terminal, the message should be terminated with the EOF key
The length of the message is limited to 20 lines. For every invocation of wall a notification will be written to syslog, with facility
LOG_USER and level LOG_INFO.
OPTIONS -n Suppresses the normal banner printed by wall, changing it to "Remote broadcast message". This option is only available for root if
wall is installed set-group-id, and is used by rpc.walld(8).
Wall ignores the TZ variable - the time printed in the banner is based on the system's local time.
SEE ALSO mesg(1), rpc.rwalld(8).

WALL(1) User Commands WALL(1)NAME
wall - write a message to all users
wall [-n] [-t timeout] [-g group] [message | file]
wall displays a message, or the contents of a file, or otherwise its standard input, on the terminals of all currently logged in users.
The command will wrap lines that are longer than 79 characters. Short lines are whitespace padded to have 79 characters. The command will
always put a carriage return and new line at the end of each line.
Only the superuser can write on the terminals of users who have chosen to deny messages or are using a program which automatically denies
Reading from a file is refused when the invoker is not superuser and the program is set-user-ID or set-group-ID.
OPTIONS -n, --nobanner
Suppress the banner.
-t, --timeout timeout
Abandon the write attempt to the terminals after timeout seconds. This timeout must be a positive integer. The default value is
300 seconds, which is a legacy from the time when people ran terminals over modem lines.
-g, --group group
Limit printing message to members of group defined as a group argument. The argument can be group name or GID.
Display version information and exit.
Display help text and exit.
Some sessions, such as wdm, that have in the beginning of utmp(5) ut_type data a ':' character will not get the message from wall. This is
done to avoid write errors.
