RSH(1) FreeBSD General Commands Manual RSH(1) NAME rsh -- remote shell SYNOPSIS rsh [-46Kdnx] [-t timeout] [-k realm] [-l username] host [command] 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. -K Turn off all Kerberos authentication. -d Turn on socket debugging (using setsockopt(2)) on the TCP sockets used for communication with the remote host. -k realm Cause rsh to obtain tickets for the remote host in realm instead of the remote host's realm as determined by krb_realmofhost(3). -l username Allow the remote username to be specified. By default, the remote username is the same as the local username. Kerberos authentica- tion is used, and authorization is determined as in rlogin(1). -n Redirect input from the special device /dev/null (see the BUGS sec- tion of this manual page). -x Turn on DES encryption for all data exchange. This may introduce a significant delay in response time. -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 using rlogin(1). Shell metacharacters which are not quoted are interpreted on local machine, 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.

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 rogue(6) 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 11.1 June 6, 1993 FreeBSD 11.1
