UNIX systems generally support a "remote shell" function (variants include rsh, remsh, rexec, etc.) which allows execution of a command on a remote system. The command RUNRMTCMD is the nearest equivalent in OS/400. However, OS/400 does not have the equivalent of the "rexecd" daemon which processes remote command requests from other systems. It is possible for the remote FTP client to trigger processes on an OS/400 server by means of the “QUOTE RCMD” command, which is the OS/400 nearest equivalent.
