NAME

xx − remote shell

SYNOPSIS

xx [-x] host command

DESCRIPTION

xx connects to the specified host, and executes the specified command.  xx 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; xx normally terminates when the remote command does. 

All echoing takes place at the remote site, so that (except for delays) xlogin is transparent.  To make the flow control function on the calling machine, use the -x flag.  Flow control using ^S and ^Q , and flushing input and output on interrupts are handled properly. 

The remote login name must be equivalent (in the sense of sh(1)) to the originating account; no provision is made for specifying a password with a command.

If you omit command, xx host C shell is executed. 

Shell metacharacters which are not quoted are interpreted on the local machine, while quoted metacharacters are interpreted on the remote machine.  Thus the command

$ xx otherhost cat remotefile >> localfile

appends the remote file remotefile to the local file localfile, while

$ xx otherhost cat remotefile ">>" otherremotefile

appends remotefile to otherremotefile.

BUGS

If you are using csh(1) and put an xx(1C) in the background without redirecting its input away from the terminal, it will block even if no reads are posted by the remote command. 

You cannot run an interactive command (like vi(1)); use xlogin.

Stop signals stop the local xx process only; this is arguably wrong, but currently hard to fix for reasons too complicated to explain here.
