Here is the script:
Code:
#!/bin/bash

function nu ()
{
        for var in {0..5}; do printf "$var, "; done; echo
}

ssh host "$(typeset -f); nu"

Here is the output:
Code:
./r.sh 
Badly placed ()'s.
{: Command not found.
++ null function ++
}: Command not found.
nu: Command not found.

Next step is to run it as other user using su command but this is the start.

Thank you in advanced.
As others have pointed out, setting a function on your system doesn't make the function exist on a remote system.

I'll also point out that $(typeset -f) is run on your local system, before ssh is even run. This is because you've put it inside double quotes, which will evaluate variables, backticks, and $( ) before processing the command.

perl::critic::command

Perl::Critic::Command(3)				User Contributed Perl Documentation				  Perl::Critic::Command(3)

NAME

       Perl::Critic::Command - Guts of perlcritic.

SYNOPSIS

	   use Perl::Critic::Command qw< run >;

	   local @ARGV = qw< --statistics-only lib bin >;
	   run();

DESCRIPTION

       This is the implementation of the perlcritic command.  You can use this to run the command without going through a command interpreter.

INTERFACE SUPPORT

       This is considered to be a public class.  However, its interface is experimental, and will likely change.

IMPORTABLE SUBROUTINES

       "run()"
	   Does the equivalent of the perlcritic command.  Unfortunately, at present, this doesn't take any parameters but uses @ARGV to get its
	   input instead.  Count on this changing; don't count on the current interface.

TO DO

       Make "run()" take parameters.  The equivalent of @ARGV should be passed as a reference.

       Turn this into an object.
