wall – send a message to everybodyâs 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 wallâs standard input. When using the standard input from a terminal, the message should be terminated with the EOF key (usually Control-D). The length of the message is limited to 22 lines. For every invocation of wall a notification will be written to syslog, with facility LOG_USER and level LOG_INFO.


$ wall "mesage for ankit : netstat -anp|grep "10.3.10""
