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

uux

UUX(1C) 																   UUX(1C)

NAME

       uux - unix to unix command execution

SYNOPSIS

       uux [ - ] command-string

DESCRIPTION

       Uux will gather 0 or more files from various systems, execute a command on a specified system and send standard output to a file on a spec-
       ified system.

       The command-string is made up of one or more arguments that look like a shell command line, except that the command and file names  may	be
       prefixed by system-name!.  A null system-name is interpreted as the local system.

       File names may be one of(1) a full pathname;

	      (2) a pathname preceded by ~xxx; where xxx is a userid on the specified system and is replaced by that user's login directory;

	      (3) anything else is prefixed by the current directory.

       The `-' option will cause the standard input to the uux command to be the standard input to the command-string.

       For example, the command

	      uux "!diff usg!/usr/dan/f1 pwba!/a4/dan/f1 > !fi.diff"

       will get the f1 files from the usg and pwba machines, execute a diff command and put the results in f1.diff in the local directory.

       Any  special  shell characters such as <>;| should be quoted either by quoting the entire command-string, or quoting the special characters
       as individual arguments.

FILES

       /usr/uucp/spool - spool directory
       /usr/uucp/* - other data and programs

SEE ALSO

       uucp(1)
       D. A. Nowitz, Uucp implementation description

WARNING

       An installation may, and for security reasons generally will, limit the list of commands executable on behalf of an incoming  request  from
       uux.  Typically, a restricted site will permit little other than the receipt of mail via uux.

BUGS

       Only the first command of a shell pipeline may have a system-name!.  All other commands are executed on the system of the first command.
       The use of the shell metacharacter * will probably not do what you want it to do.
       The shell tokens << and >> are not implemented.
       There is no notification of denial of execution on the remote machine.
