{{Further|Remote Shell}}

{{code|rsh}} opens a [[Shell (computing)|shell]] on a remote computer without a [[login]] procedure. Once connected, the user can execute commands on the remote computer through the shell's [[command-line interface]]. {{code|rsh}} passes input and output through the [[standard streams]], and it sends [[standard output]] to the user's [[Virtual console|console]]. Over the network, [[standard input]] and standard out flow through TCP port 514, while [[Standard_streams#Standard_error_(stderr)|Standard Error]] flows through a different TCP port, which the {{code|rsh}} [[Daemon (computing)|daemon]] ({{code|rshd}}) opens.<ref>{{cite book |url=https://books.google.com/books?id=-hF7sqwrcrwC&pg=PA154 |title=CCSP: Secure PIX and Secure VPN Study Guide |last1=Edwards |first1=Wade |last2=Lancaster |first2=Tom |last3=Quinn |first3=Eric |last4=Rohm |first4=Jason |last5=Tow |first5=Bryant|publisher=[[Sybex]] |page=154 |isbn=0-7821-4287-7 |year=2004 |via=Google Books |access-date=2018-03-07}}</ref>
