on(NC)
on --
execute a command remotely
Syntax
on [ -i ] [ -n ] [ -d ]
host command [ argument ] ...
Description
The on command is used to execute commands on
another system, in an environment similar to that invoking
the command. All environment variables are passed and the
current working directory is preserved. To preserve the
working directory, the working filesystem must be either
already mounted on the host or be exported to it. Relative
pathnames will only work if they are within the current
filesystem; absolute pathnames may cause problems.
Standard input is connected to standard input of the remote
command; standard output and standard error from the remote
command are sent to the corresponding files for the
on command.
Options
-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 are propagated.
-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 command. For example, -n is
necessary when running commands in the background with job
control.
-d-
debug mode: print out messages as work is being done
Diagnostics
unknown host-
host name not found
cannot connect to server-
host down or not running the server
cannot find .-
problem finding the working directory
cannot locate mount point-
problem finding current filesystem
Other error messages may be passed back from the server.
Limitations
To use on, user must have an account on the
remote machine.
