{{Main|Berkeley r-commands}}

''Rsh'' originated as part of the [[Berkeley Software Distribution|BSD Unix]] [[operating system]], along with [[rcp (Unix)|rcp]], as part of the [[rlogin]] package on 4.2BSD in 1983. rsh has since been ported to other operating systems. 

The <code>rsh</code> command has the same name as another common UNIX utility, the [[restricted shell]], which first appeared in [[PWB/UNIX]]; in [[System V|System V Release 4]], the restricted shell is often located at <code>/usr/bin/rsh</code>.

As other [[Berkeley r-commands#Security|Berkeley r-commands]] which involve user authentication, the rsh [[communication protocol|protocol]] is not [[computer security|secure]] for network use, because it sends [[cryptography|unencrypted information]] over the network, among other reasons. Some implementations also [[authentication|authenticate]] by sending unencrypted [[password]]s over the network. rsh has largely been replaced with the [[Secure Shell|secure shell]] (ssh) program, even on local networks.<ref>{{Cite web |title=SSH, the Secure Shell: The Definitive Guide |url=https://www.researchgate.net/publication/234765974 |access-date=2023-11-11 |work=www.researchgate.net |archive-date=2023-11-11 |archive-url=https://web.archive.org/web/20231111073413/https://www.researchgate.net/publication/234765974_SSH_the_Secure_Shell_The_Definitive_Guide |url-status=live }}</ref><ref>{{Cite web |title=Secure Shell Protocol – Everything you need to know |url=https://dev.to/me_jessicahowe/secure-shell-protocol-everything-you-need-to-know-5g5j |access-date=2023-11-11 |work=dev.to}}</ref>
