. Unix considers any device attached to the system to be a file. And that includes your terminal! . By default, a command treats your terminal as the standard input file from which to read in information. Your terminal is also treated as the standard output file to which information is sent from the command. This action can be changed by redirecting standard input and standard output from and to any other file. Redirecting standard input . Redirecting standard output . Appending standard output to a file .

multi-rsh is a perl script which runs the same command on multiple machines, in parallel, and provides reasonable, adjustable timeouts for those machines which fail to answer. Both standard output and standard error are returned through the same channel, and all output has the hostname prepended to each line. Multi-rsh must be run as root (remote jobs can be set to run as any user, see Options below). ... Neither form allows you to directly pass input to the remote programs. ...
