on - execute a command remotely
on [ -i ] [ -n ] [ -d ] host command [ argument ] ...
The on program is used to execute commands on another system, in an
environment similar to that invoking the program. All environment
variables are passed, and the current working directory is preserved. To
preserve the working directory, the working file system must be either
already mounted on the host or be exported to it. Relative path names
will only work if they are within the current file system; absolute path
names may cause problems.
Standard input is connected to standard input of the remote command, and
standard output and standard error from the remote command are sent to
the corresponding files for the on command.
-i Interactive mode: use remote echoing and special character
processing. This option is needed for programs that expect to be
talking to a terminal. All terminal modes and window size changes
-n No Input: this option causes the remote program to get end-of-file
when it reads from standard input, instead of passing standard input
from the standard input of the on program. For example, -n is
necessary when running commands in the background with job control.
-d Debug mode: print out some messages as work is being done.
Host name not found.
cannot connect to server
Host down or not running the rexd server.
can't find .
Problem finding the working directory.
can't locate mount point
Problem finding current file system.
Other error messages may be passed back from the server.
The window size is not set properly when executing interactively on Sun
