Execute command from terminal on remote machine
Hi All,

I want to execute some commands on unix machine from the mac machne. I have two options for doing so, I am confused which is the best way of doing. Here are two options.

Requirement:
Execute command on the remote server machine. Commands to be executed itself contain arguments to be passed to some script.

Option1:
1. Perl script to do ssh and expect to connect to the remote machine and execute command over there.
Complexity/Overhead: If I need to execute any new command, I have to overwrite '.exp' file.

2. Use Net::SSH:Expect perl module to do so.
Complexity/Overhead: Bit difficult to install perl module on mac os. Smilie

I am confused here which is the best option which suite my requirement.

Will appreciate any guidance.

Thanks,
Ranu

xon

xon(1X) 																   xon(1X)

NAME

       xon - start an X program on a remote machine

SYNOPSIS

       xon remote-host [-access] [-debug] [-name window-name] [-nols] [-screen screen-no] [-user user-name] [command...]

OPTIONS

       Note  that  the options follow the remote host name (as they do with rlogin).  Runs xhost locally to add the remote host to the host access
       list in the X server.  This will not work unless xhost is given permission to modify the access list.  Normally, xon disconnects the remote
       process	from  stdin,  stdout  and  stderr to eliminate the daemon processes which usually connect them across the network.  Specifying the
       -debug option leaves them connected so that error messages from the remote execution are sent back to the originating host.  This specifies
       a  different  application  name	and window title for the default command (xterm).  Normally xon passes the -ls option to the remote xterm;
       this option suspends that behaviour.  This changes the screen number of the DISPLAY variable passed to the remote command.  By default, xon
       simply  uses  rsh/remsh/rcmd  to  connect to the remote machine using the same user name as on the local machine.  This option cause xon to
       specify an alternative user name.  This will not work unless you have authorization to access the remote account, by placing an appropriate
       entry in the remote users file.

DESCRIPTION

       The  xon  program  runs the specified command (default xterm -ls) on the remote machine using rsh, remsh, or rcmd.  xon passes the DISPLAY,
       XAUTHORITY and XUSERFILESEARCHPATH environment variables to the remote command.

       When no command is specified, xon runs 'xterm -ls'.  It additionally specifies the application name to be 'xterm-remote-host' and the  win-
       dow title to be 'remote-host'.

       xon can only work when the remote host will allow you to log in without a password, by having an entry in the file permitting access.

BUGS

       xon can get easily confused when the remote-host, user-name or various environment variable values contain white space.

       xon has no way to send the appropriate X authorization information to the remote host.
