RSH(1) FreeBSD General Commands Manual RSH(1) NAME rsh -- remote shell SYNOPSIS rsh [-46dnN] [-l username] [-t timeout] host [command] DEPRECATION NOTICE rsh is deprecated and will be removed from future versions of the FreeBSD base system. If rsh is still required, it can be installed from ports or packages (net/bsdrcmds). DESCRIPTION The rsh utility executes command on host. The rsh utility copies its standard input to the remote command, the standard output of the remote command to its standard output, and the standard error of the remote command to its standard error. Interrupt, quit and terminate signals are propagated to the remote command; rsh nor- mally terminates when the remote command does. The options are as fol- lows: -4 Use IPv4 addresses only. -6 Use IPv6 addresses only. -d Turn on socket debugging (using setsockopt(2)) on the TCP sockets used for communication with the remote host. -l username Allow the remote username to be specified. By default, the remote username is the same as the local username. Authorization is de- termined as in rlogin(1). -N Opposite to -n option: do not send the "end of file" (EOF) indica- tion for input stream to the remote host. This option makes the rsh utility compatible with protocol implementations confused by re- ceiving EOF, like some Cisco IOS versions. Disables -n. -n Redirect input from the special device /dev/null (see the BUGS sec- tion of this manual page). Disables -N. -t timeout Allow a timeout to be specified (in seconds). If no data is sent or received in this time, rsh will exit. If no command is specified, you will be logged in on the remote host us- ing rlogin(1). Shell metacharacters which are not quoted are interpreted on local ma- chine, while quoted metacharacters are interpreted on the remote machine. For example, the command rsh otherhost cat remotefile >> localfile appends the remote file remotefile to the local file localfile, while rsh otherhost cat remotefile ">>" other_remotefile appends remotefile to other_remotefile. FILES /etc/hosts SEE ALSO rlogin(1), setsockopt(2), rcmd(3), ruserok(3), hosts(5), hosts.equiv(5), rlogind(8), rshd(8) HISTORY The rsh command appeared in 4.2BSD. BUGS If you are using csh(1) and put a rsh in the background without redirect- ing its input away from the terminal, it will block even if no reads are posted by the remote command. If no input is desired you should redirect the input of rsh to /dev/null using the -n option. You cannot run an interactive command (like ee(1) or vi(1)) using rsh; use rlogin(1) instead. Stop signals stop the local rsh process only; this is arguably wrong, but currently hard to fix for reasons too complicated to explain here. FreeBSD 13.0 July 3, 2017 FreeBSD 13.0
