rcmd executes
command on
host.
rcmd 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;
rcmd normally terminates when the remote command does. The options are as follows:
-d
The
-d option turns on socket debugging (using
setsockopt(2)) on the TCP sockets used for communication with the remote host.
-l
By default, the remote username is the same as the local username. The -l option allows the remote name to be specified.
-u
The -u option allows the local username to be specified. Only the superuser is allowed to use this option.
-n
The
-n option redirects input from the special device
/dev/null (see the
BUGS section of this manual page).
Shell metacharacters which are not quoted are interpreted on local machine, while quoted metacharacters are interpreted on the remote machine. For example, the command
rcmd otherhost cat remotefile >> localfile
appends the remote file
remotefile to the local file
localfile, while
rcmd otherhost cat remotefile ">>" other_remotefile
appends
remotefile to
other_remotefile.
