The remsh command starts a shell on a remote host, performs some client activity (often starting a terminal emulator on that host), and redirects the display back to your original system if desired.
It has the syntax:
remsh remote -n client -display system:display[.screen]
remote--the remote host name
client--the program you want to run on the remote host
system:display[.screen]--the host and display on which the results are to be displayed
For example, the following command runs xload on the remote host named there, and directs output back to your system, here.
remsh there -n /usr/bin/X11/xload -display here:0.0 &
