The Kerberos V5 rsh program works exactly like the standard
UNIX rlogin program, with the following Kerberos features added:
     
For example, if your Kerberos tickets allowed you to run programs on the
host 
 trillium@example.com as root, you could
run the date program as follows:
     shell% rsh trillium.example.com -l root -x date
     This rsh session is using DES encryption for all data transmissions.

If you forwarded your Kerberos tickets, rsh automatically
destroys them when it exits.  The full set of options to Kerberos V5
rsh are discussed in the Reference section of this manual.
