z/OS UNIX send command

The z/OS® UNIX interface has one of the following formats, where userid is a target userid, pid is the process ID of a target thread pool and jobname is the job name of a target RSE daemon. The -c option clears the message buffer.
send [–u userid[,userid,…]] [–d jobname] message
send [–p pid[,pid,…]] [–d jobname] message
send –c [–d jobname]
  • The send command is located in /usr/lpp/IBM/zexpl/bin/send, unless you used a different path during the SMP/E install of z/OS Explorer.
  • By default, a message is delivered to all users of all active RSE daemons.
  • A message sent using the -p filter is not stored, only users active in the referenced thread pools will receive it.
  • The message text is interpreted by the z/OS UNIX shell before it is passed to the send command. Use standard techniques to avoid interpretation by the shell if this is not desired.
  • The maximum length of the send command including the options and message text is limited to 320 bytes.
Note: The /usr/lpp/IBM/zexpl/bin/ path is part of the PATH variable when a user opens a z/OS UNIX command line in the z/OS Explorer client.
